I'm trying to write a Form Builder system.
Now, i reached to gathering information section and at this section i need to grouping the information to three group like:
"Short-Response" for text inputs
"Long-Response" for textarea
and "Option-Response" for radio, checkbox and dropdown
in Form page view, system create the form, based on database records.
I'm using suffix for inputs based on those group as i said earlier, like these:
<inputs name="dynamicpart_short" value="" />
<textarea name="dynamicpart_logn"></textarea>
Now, In server side i want to gather these information and group them.
I'm using
for each item in Request.Form
Next
But how i can create a loop based on inputs suffix like "_short" or "_long" and ....
means each suffix has it's own loop!
PS:
inputs have a name with two parts, first part is dynamic and is a random numbers!
Like this: name="15_short"
"item" will have the name of the form field, use a string function to check if it has short or long in it:
for each item in Request.Form
if instr(item,"_short")<>0 then
'do something
elseif instr(item,"_long")<>0 then
'do something else
'.....
end if
Next

I have a form that submits parameters to a query, then opens the resulting record in another form. The problem is, whenever there is more than one record it automatically puts the first one into the from without any kind of option to choose the record I want. I have a macro set up on the search button on the first form that submits the parameters to the query and then displays it in the second form, I've tried to set up another macro in between the two, but I don't know if it's possible to set up the expression creator to check the number of rows resulting from a query. Is it possible to modify the query to create a prompt to choose which record I want? Or should I change something else?
This is the query:(automatically created by access)
SELECT CHILD.CHILD_L_NAME, CHILD.CHILD_F_NAME, CHILD.DOB, CHILD.GENDER, CHILD.DAYS_IN_CARE,
CHILD.HOURS_PER_DAY, CHILD.ENROLLMENT_DATE, CHILD.CHILD_ADDRESS, CHILD.CHILD_CITY,
CHILD.CHILD_ZIP, CHILD.CHILD_STATE, CHILD.CLASSROOM, CHILD.SNACK, CHILD.LAST_UPDATED, CHILD.CIN
FROM CHILD
WHERE (((CHILD.CHILD_L_NAME)=[Forms]![Search]![L_NAME]) AND
((CHILD.CHILD_F_NAME)=[Forms]![Search]![F_NAME])) OR
(((CHILD.CHILD_L_NAME)=[Forms]![Search]![L_NAME]) AND
((CHILD.DOB)=[Forms]![Search]![DOB])) OR
(((CHILD.DOB)=[Forms]![Search]![DOB])) OR
(((CHILD.CHILD_L_NAME)=[Forms]![Search]![L_NAME]));
If I understood well your problem and you use VBA it's quite easy to do.
You can create a reduced query based on the query you're creating with the button. This new query should include all and only the fields that allows you to discriminate beetwen the records to show in the 2nd form.
For instance it could include LastName, FirstName and classroom to select between children with same full name.
You can count the number of records of this 2nd query and if greater than 1 it means that you have more than one children to show.
So you can use this 2nd query to populate a combo-box or a listbox for selecting the record you really want to show.
When number of records is 1 you can simply skip the listbox population using an if statement on recordcount.
Next step is opening the form with the selected (or unique) record.

This Question was asked in interview but i was unable to answer it
please any one can tell me how to do this ?
i have two textboxs txtInput and txtOutput
When user clicks the btnSubmit, he should get the number written in txtInput in words in txtOutput. Eg. if user enters 100 in txtInput, he should get hundred in txtOutput
Prumably this is JS. If it is the you can setup an event listener on the submit button and disable the default behavior. Pass the input value to a function that builds the number string and update the dom element for the output textbox with that return result.
If you're using a round trip to the server for the calculation then just ignore all the dom stuff and return the page with the appropriate values set.
If you're using a front end framework then this gets easier but more specific to the framework.
thanks ..found solution here
.NET convert number to string representation (1 to one, 2 to two, etc...)
Basically I have a news page which stores headlines, stories, and a unique story identifier in a SQL database. I want to be able to create a hyperlink on a webpage to the pictures.
so when someone selects a news story from a drop down menu (which uses the headline) and presses submit I want to pass the storyID, which is a unique identifier, to a spot in a hyperlink. so if it was story 134 then then link would look like:
I know the SQL statement would look like:
SELECT StoryID from db.News
Where Headline = {The headline selected in the dropdown menu}
the dropdown menu is called NewsDrop
this would be an ASPX page written with a VB code base
SO I guess I need help passing the variables along to the search string and the hyperlink.
Not even sure if this is even possible.
There are a number of options available to achieve this, the most common would be to using a query string in the hyperlinks in your drop down menu to send a parameter to a SQL stored procedure which would use it in a variable in your select statement. So basically the hyperlinks you have in the drop down menu would be appended with ?storyID=<uniquestoryid> and on the far end SELECT StoryID from db.News Where StoryID = #StoryID it would be less efficient to use the headline from the link as a query string and variable in the where clause as you have shown but if that is your only option it could be done.
However you should proceed carefully when using query strings here is a link to a good basic article about query strings and another link about best practices.
Is there a way to iteratively reference an ASP.NET control based on it's name pattern? Perhaps by a "pointer" or something?
What I have are a large set of comboboxes (each with an associated DropDownList and TextBox control). The DropDownList always has an item selected by default, but the use may wish to submit a NULL value. I come up with the following code to handle three cases: NULL, Existing Item, New Item.
'TextBoxControl & DropDownListControl should iteratively reference their
' respective TextBox & DropDownList controls by the actual control name
If StrComp(TextBoxControl.Text, DropDownListControl.SelectedItem.ToString) = 0 Then
'When an Existing Item is selected, Do Something
ElseIf Not TextBoxControl.Text = "" Then
'When a New Item is entered, Validate & Do Something
Else
'When NULL, Do Something
End If
The problem is, with so many comboboxes, I could easily end up with hundreds of lines of code. I wish to handle this in a more dynamic way, but I do not know if it is possible to reference controls in this way. Say I wanted to reference all the TextBox Controls and DropDownList Controls, respectively.
I can do string formatting with a given naming pattern to generate a name ID for any of the controls because they are all named with the same pattern. For example by attaching a specific suffix, say "_tb" for TextBox Controls and "_ddl" for DropDownList Controls:
Left(item.SelectedItem.ToString, item.SelectedItem.ToString.Length - 3) + "_tb"
Can this sort of thing be done in VB? Ultimately, my goal is to take the value entered/selected by the user, if any, and send it to a stored procedure on SQL Server for insertion into the database.
Yes. Write your code inside of a function having parameters for the textbox and the dropdown, and then write the function in terms of those two parameters. Then you simply call that function for every set instead of copy/pasting code everywhere.
Don't attempt choosing things by name. That's fragile and imposes machine requirements on a field that'd designed for human consumption.
I am not sure if the samething that applies VBA will apply to your situation, but I had the same issue and was able to use:
Me.MultiPage1.Pages(1).Controls("ref" & i + 1).Value
where controls encompasses all controls on the userform ("Me"). So if the controls in your program conform to a consecutive naming structure it is easy handle if the above applies vb.net
I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row.
I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="order-23" or name="order[23]", but how can I translate that name so that I can update the related record in the database?
EDIT: One solution I can think of would be to iterate through every form field in the FormCollection, and if the name of the field matches the pattern, then I will extract the number from that field-name and process it.
However, I feel that there must be a much easier way to go about it - this method would likely involve a fair bit of string processing on each field, and there would possibly fall over if I have to add extra fields for each row later on.
Don't you have a list of IDs after postback? I believe you should not depend on what IDs are actually sent from the form, as anybody could change the IDs on the form to whatever they want, so it's a security issue. So you should after postback have a list of IDs you want to update (the same list you used to create the form with). In that case, you know exactly what id string you should use to retrieve the value from FormCollection.
In case you really can't get the list of IDs you are going to update, just use the FormCollection iteration as you suggested in your comment. The string processing is not that expensive in comparation with all other stuff being done at request processing.
If you have the names, then simply read the values by using Request.Form["order-23"] or re-create the controls in page pre-init and you'll have access to the values in your save event directly through the created controls.
I've done this loads in my CMS.
Essentially i sort of cheated.
The idea is something like this ....
render the form to the client, then look at the source code gneerated.
You should see that it generated a form tag with an action attribute.
When you click the submit button the form will be sent to that url so in the case of an order submission you would post the page back to OrderPage.aspx?OrderId=xxxx
then on the server you would build an update statement for your db that contained something like ...
"Update orders where order id =" + request.querystring["OrderId"]
So how do you update the action ...
In the calling page lets say you have a link called "New Order", when that link is clicked you need to do 2 things ...
redirect to this page.
generate an order id for this new order.
ok the first is simple, simply link it to this page.
the second ...
if this page is not a postback if(!IsPostback) { /* get a new id */ } depending on your order id's this may involve generating a new guid or doing something like getting the next number in a list by doing a select max(id) from a db.
once you have this new id you should still be in the page_load event.
this.form.Action = this.form.Action + "?OrderId=" + yourNewOrderId;
... tada ...
Send page back to the client.
view the source.
