I accidentally removed the references from one of my projects and then carefully put them back in. However now I am throwing errors in code the was functioning perfectly so I think I must still be missing a reference unless something else was broken in the process. Here is the current error:
The variable 'button1' is either undeclared or was never assigned.
But here is the code in Form1.Designer.cs:
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
...
//
// button1
//
this.button1.Location = new System.Drawing.Point(235, 382);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(125, 23);
this.button1.TabIndex = 0;
this.button1.Text = "Generate Report";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
...
this.Controls.Add(this.button1);
...
private System.Windows.Forms.Button button1;
The last seven lines are all throwing this error. Any advice is appreciated.
Regards.
EDIT: Here is code relevant to the comments:
public partial class Severity3RetailNetworkTrackingLog : Form
{
public Severity3RetailNetworkTrackingLog()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
Where Form1 has been changed to Severity3RetailNetworkTrackingLog.
I suspect you are missing the member variable definition
class Form1 {
/* lots of windows form designer code */
/* some other member variables */
System.Windows.Forms.Button button1;
}
Within your class definition.
Turns out that VS Express 2010 was just misbehaving. I commented out all of the offending code and still got the same errors with the same line numbers. So I closed and opened VS and everything is back to normal.

I have a VS extensions command based on the default template. It has CommandFlag's TextChanges and TogglePatternAvailable. Depending on a config setting its initial state should be checked, however, this does not appear to be possible.
This is what I want to see on the first load:
I've tried setting Checked to true in the constructor of the command after creating the menu item:
menuItem1 = new OleMenuCommand(ExecuteCommand1, _, BeforeQueryStatus, new CommandID(CommandSet, Command1Id));
menuItem1.Checked = true; // This does not work
I've also tried using the BeforeQueryStatus to change the initial checked state, but it does not seem to be called when opening the Tools menu. Could this be a bug???:
private void BeforeQueryStatus(object sender, EventArgs e)
{
ThreadHelper.JoinableTaskFactory.Run(async delegate
{
await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync(package.DisposalToken);
menuItem1.Checked = true;
});
}
Clicking the menu item once does trigger BeforeQueryStatus and the state is checked after that, proving that the code does work.
How can I set the initial checked state of the menu item to true depending on a config setting, so in code?
In the end I managed to get it to work by adding the ProvideAutoLoad attribute to my Package. It is unclear if this is the correct way to do this. The pacakge class now looks like this:
[PackageRegistration(UseManagedResourcesOnly = true, AllowsBackgroundLoading = true)]
[Guid(PackageGuidString)]
[ProvideMenuResource("Menus.ctmenu", 1)]
[ProvideAutoLoad(VSConstants.UICONTEXT.NoSolution_string, PackageAutoLoadFlags.BackgroundLoad)]
[ProvideAutoLoad(VSConstants.UICONTEXT.SolutionExists_string, PackageAutoLoadFlags.BackgroundLoad)]
public sealed class MyPackage : AsyncPackage { ... }
I'm currently trying to implement an automated bug reporter for a Flex application, and would like to return error messages to a server along with the function/line number that caused the error. Essentially, I'm trying to get the getStackTrace() information without going into debug mode, because most users of the app aren't likely to have the debug version of flash player.
My current method is using the UncaughtErrorEvent handler to catch errors that occur within the app, but the error message only returns the type of error that has occurred, and not the location (which means it's useless). I have tried implementing getStackTrace() myself using a function name-grabber such as
private function getFunctionName (callee:Function, parent:Object):String {
for each ( var m:XML in describeType(parent)..method) {
if ( this[m.#name] == callee) return m.#name;
}
return "private function!";
}
but that will only work because of arguments.callee, and so won't go through multiple levels of function calls (it would never get above my error event listener).
So! Anyone have any ideas on how to get informative error messages through the global
error event handler?
EDIT: There seems to be some misunderstanding. I'm explicitly avoiding getStackTrace() because it returns 'null' when not in debug mode. Any solution that uses this function is what I'm specifically trying to avoid.
Just noticed the part about "I don't want to use debug." Well, that's not an option, as the non-debug version of Flash does not have any concept of a stack trace at all. Sucks, don't it?
Not relevant but still cool.
The rest is just for with the debug player.
This is part of my personal debug class (strangely enough, it is added to every single project I work on). It returns a String which represents the index in the stack passed -- class and method name. Once you have those, line number is trivial.
/**
* Returns the function name of whatever called this function (and whatever called that)...
*/
public static function getCaller( index:int = 0 ):String
{
try
{
throw new Error('pass');
}
catch (e:Error)
{
var arr:Array = String(e.getStackTrace()).split("\t");
var value:String = arr[3 + index];
// This pattern matches a standard function.
var re:RegExp = /^at (.*?)\/(.*?)\(\)/ ;
var owner:Array = re.exec(value);
try
{
var cref:Array = owner[1].split('::');
return cref[ 1 ] + "." + owner[2];
}
catch( e:Error )
{
try
{
re = /^at (.*?)\(\)/; // constructor.
owner = re.exec(value);
var tmp:Array = owner[1].split('::');
var cName:String = tmp.join('.');
return cName;
}
catch( error:Error )
{
}
}
}
return "No caller could be found.";
}
As a side note: this is not set up properly to handle an event model -- sometimes events present themselves as either not having callers or as some very weird alternate syntax.
You don't have to throw an error to get the stack trace.
var myError:Error = new Error();
var theStack:String = myError.getStackTrace();
good reference on the Error class
[EDIT]
Nope after reading my own reference getStackTrace() is only available in debug versions of the flash player.
So it looks like you are stuck with what you are doing now.
Have a real puzzler here. I'm using Atalasoft DotImage to allow the user to add some annotations to an image. When I add two annotations of the same type that contain text that have the same name, I get a javascript permission denied error in the Atalasoft's compressed js. The error is accessing the style member of a rule:
In the debugger (Visual Studio 2010 .Net 4.0) I can access
h._rule
but not
h._rule.style
What in javascript would cause permission denied when accessing a membere of an object?
Just wondering if anyone else has encountered this. I see several people using Atalasoft on SO and I even saw a response from someone with Atalasoft. And yes, I'm talking to them, but it never hurts to throw it out to the crowd. This only happens in IE8, not FireFox.
Thanks, Brian
Updates: Yes, using latest version: 9.0.2.43666
By same name (see comment below) I mean, I created default annotations and they are named so they can be added with javascript later.
// create a default annotation
TextData text = new TextData();
text.Name = "DefaultTextAnnotation";
text.Text = "Default Text Annotation:\n double-click to edit";
//text.Font = new AnnotationFont("Arial", 12f);
text.Font = new AnnotationFont(_strAnnotationFontName, _fltAnnotationFontSize);
text.Font.Bold = true;
text.FontBrush = new AnnotationBrush(Color.Black);
text.Fill = new AnnotationBrush(Color.Ivory);
text.Outline = new AnnotationPen(new AnnotationBrush(Color.White), 2);
WebAnnotationViewer1.Annotations.DefaultAnnotations.Add(text);
In javascript:
CreateAnnotation('TextData', 'DefaultTextAnnotation');
function CreateAnnotation(type, name) {
SetAnnotationModified(true);
WebAnnotationViewer1.DeselectAll();
var ann = WebAnnotationViewer1.CreateAnnotation(type, name);
WebThumbnailViewer1.Update();
}
There was a bug in an earlier version that allowed annotations to be saved with the same unique id's. This generally doesn't cause problems for any annotations except for TextAnnotations, since they use the unique id to create a CSS class for the text editor. CSS doesn't like having two or more classes defined by the same name, this is what causes the "Permission denied" error.
You can remove the unique id's from the annotations without it causing problems. I have provided a few code snippets below that demonstrate how this can be done. Calling ResetUniques() after you load the annotation data (on the server side) should make everything run smoothly.
-Dave C. from Atalasoft
protected void ResetUniques()
{
foreach (LayerAnnotation layerAnn in WebAnnotationViewer1.Annotations.Layers)
{
ResetLayer(layerAnn.Data as LayerData);
}
}
protected void ResetLayer(LayerData layer)
{
ResetUniqueID(layer);
foreach (AnnotationData data in layer.Items)
{
LayerData group = data as LayerData;
if (group != null)
{
ResetLayer(data as LayerData);
}
else
{
ResetUniqueID(data);
}
}
}
protected void ResetUniqueID(AnnotationData data)
{
data.SetExtraProperty("_atalaUniqueIndex", null);
}
I'm building a Flex app which requires me to download files.
I have the following code:
public function execute(event:CairngormEvent) : void
{
var evt:StemDownloadEvent = event as StemDownloadEvent;
var req:URLRequest = new URLRequest(evt.data.file_path);
var localRef:FileReference = new FileReference();
localRef.addEventListener(Event.OPEN, _open);
localRef.addEventListener(ProgressEvent.PROGRESS, _progress);
localRef.addEventListener(Event.COMPLETE, _complete);
localRef.addEventListener(Event.CANCEL, _cancel);
localRef.addEventListener(Event.SELECT, _select);
localRef.addEventListener(SecurityErrorEvent.SECURITY_ERROR, _securityError);
localRef.addEventListener(IOErrorEvent.IO_ERROR, _ioError);
try {
localRef.download(req);
} catch (e:Error) {
SoundRoom.logger.log(e);
}
}
As you can see, I hooked up every possible event listener as well.
When this executes, I get the browse window, and am able to select a location, and click save. After that, nothing happens.
I have each event handler hooked up to my logger, and not a single one is being called! Is there something missing here?
The problem seems to be with my command being destroyed before this could finish.
For a proof of concept, I set my localRef variable to be static instead of an instance variable, and everything went through successfully! I guess Cairngorm commands kill themselves asap!
I want to bind a List to a GridView on a web page, but override the way the property names display via annotation. I thought System.ComponentModel would work, but this doesn't seem to work. Is this only meant for Windows Forms?:
using System.ComponentModel;
namespace MyWebApp
{
public class MyCustomClass
{
[DisplayName("My Column")]
public string MyFirstProperty
{
get { return "value"; }
}
public MyCustomClass() {}
}
Then on the page:
protected void Page_Load(object sender, EventArgs e)
{
IList<MyCustomClass> myCustomClasses = new List<MyCustomClass>
{
new MyCustomClass(),
new MyCustomClass()
};
TestGrid.DataSource = myCustomClasses;
TestGrid.DataBind();
}
This renders with "MyFirstProperty" as the column header rather than "My Column." Isn't this supposed to work?
When using .net 4 or later you can use gridview1.enabledynamicdata(typeof(mytype)). I haven't looked at all the types you can use there but I know the [displayname("somename")] works well but the [browsable(false)] doesn't omit the column from the grid. It looks like a knit one slip one from MS. at least you can easily rename column names and to omit a column I just declare a variable instead of using a property. It has the same effect...
Just by the way, using the designer to create columns is the easy way out but to just show a different column name takes way to much time especially with classes with many fields.
What SirDemon said...
The answer appears to be no, you can't. At least not out of the box.
The System.Web.UI.WebControls.GridView uses reflected property's name:
protected virtual AutoGeneratedField CreateAutoGeneratedColumn(AutoGeneratedFieldProperties fieldProperties)
{
AutoGeneratedField field = new AutoGeneratedField(fieldProperties.DataField);
string name = fieldProperties.Name; //the name comes from a PropertyDescriptor
((IStateManager) field).TrackViewState();
field.HeaderText = name; //<- here's reflected property name
field.SortExpression = name;
field.ReadOnly = fieldProperties.IsReadOnly;
field.DataType = fieldProperties.Type;
return field;
}
While System.Windows.Forms.DataGridView uses DisplayName if available:
public DataGridViewColumn[] GetCollectionOfBoundDataGridViewColumns()
{
...
ArrayList list = new ArrayList();
//props is a collection of PropertyDescriptors
for (int i = 0; i < this.props.Count; i++)
{
if (...)
{
DataGridViewColumn dataGridViewColumnFromType = GetDataGridViewColumnFromType(this.props[i].PropertyType);
...
dataGridViewColumnFromType.Name = this.props[i].Name;
dataGridViewColumnFromType.HeaderText = !string.IsNullOrEmpty(this.props[i].DisplayName) ? this.props[i].DisplayName : this.props[i].Name;
}
}
DataGridViewColumn[] array = new DataGridViewColumn[list.Count];
list.CopyTo(array);
return array;
}
Unfortunately, while you can override the CreateAutoGeneratedColumn, neither the missing DisplayName nor underlying property descriptor gets passed, and you can't override CreateAutoGeneratedColumns (although you could CreateColumns).
This means you'd have to iterate over reflected properties yourself and in some other place.
If all you care about is the header text in GridView, just use the HeaderText property of each field you bind. If you're autogenerating the columns, you just set the HeaderText after you've bound the GridView.
If you want a GridView that takes into account some attribute you placed on the properties of your bound class, I believe you'll need to create your own GridView.
I may be wrong, but I've not seen any ASP.NET Grid from control vendors (at least Telerik , Janus Systems and Infragistics) do that. If you do it, maybe sell the idea to them.
Are you using .net4, what you need to do is to set enabledynamicdata on the grid view to true.
You can do it now on asp.net mvc2. It works just like that
