i made one desktop application using asp.net which convert html to PDF.
basically this application used for generate users PDF from database.
process: first of all i am converting all data to html and then convert to PDF using itextsharp but after generating some PDFs it shows blank pages
any idea or anyone face this type of issue

I am having two datasets in which first dataset has 6 rows and second dataset has 'N' Number of rows , second dataset row count keeps on changing , What I need is I need to export both the dataset to a single excelsheet . Both dataset has headers , So i need to export both dataset with header to a single excelsheet using c#. Can anyone help me with a sample code in c#
before u have to create
1. using Excel = Microsoft.Office.Interop.Excel;//in header,and Add correct refference
2. Excel.Application excelHandle1 = PrepareForExport(Ds); //add handle in calling function excelHandle1.Visible = true;
public Excel.Application PrepareForExport(System.Data.DataSet ds,string[] sheet)
{
object missing = System.Reflection.Missing.Value;
Excel.Application excel = new Excel.Application();
Excel.Workbook workbook = excel.Workbooks.Add(missing);
DataTable dt1 = new DataTable();
dt1 = ds.Tables[0];
DataTable dt2 = new DataTable();
dt2 = ds.Tables[1];
Excel.Worksheet newWorksheet;
newWorksheet = (Excel.Worksheet)excel.Worksheets.Add(missing, missing, missing, missing);
newWorksheet.Name ="Name of data sheet";
// for first datatable dt1..
int iCol1 = 0;
foreach (DataColumn c in dt1.Columns)
{
iCol1++;
excel.Cells[1, iCol1] = c.ColumnName;
}
int iRow1 = 0;
foreach (DataRow r in dt1.Rows)
{
iRow1++;
for (int i = 1; i < dt1.Columns.Count + 1; i++)
{
if (iRow1 == 1)
{
// Add the header the first time through
excel.Cells[iRow1, i] = dt1.Columns[i - 1].ColumnName;
}
excel.Cells[iRow1 + 1, i] = r[i - 1].ToString();
}
}
// for second datatable dt2..
int iCol2 = 0;
foreach (DataColumn c in dt2.Columns)
{
iCol2++;
excel.Cells[1, iCol] = c.ColumnName;
}
int iRow2 = 0;
foreach (DataRow r in dt2.Rows)
{
iRow2++;
for (int i = 1; i < dt2.Columns.Count + 1; i++)
{
if (iRow2 == 1)
{
// Add the header the first time through
excel.Cells[iRow2, i] = dt2.Columns[i - 1].ColumnName;
}
excel.Cells[iRow2 + 1, i] = r[i - 1].ToString();
}
}
return excel;
}
First you have to declare namespace:
using Excel = Microsoft.Office.Interop.Excel;
public static void Main(string[] args) {
DataTable dt1 = new DataTable("Employee");
dt1.Columns.Add("Employee ID");
dt1.Columns.Add("Employee Name");
dt1.Rows.Add("1", "ABC");
dt1.Rows.Add("2", "DEF");
dt1.Rows.Add("3", "PQR");
dt1.Rows.Add("4", "XYZ");
DataTable dt3 = new DataTable("Department");
dt3.Columns.Add("Department ID");
dt3.Columns.Add("Department Name");
dt3.Rows.Add("1", "IT");
dt3.Rows.Add("2", "HR");
dt3.Rows.Add("3", "Finance");
DataSet ds = new DataSet();
ds.Tables.Add(dt1);
ds.Tables.Add(dt3);
Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
Excel._Worksheet worksheet = null;
app.Visible = false;
worksheet = workbook.Sheets["Sheet1"];
worksheet = workbook.ActiveSheet;
worksheet.Name = "Exported from gridview";
int z = 1;
for (int x = 0; x < ds.Tables.Count; x++)
{
int r = z;
int t = r + 1;
for (int i = 1; i < ds.Tables[x].Columns.Count + 1; i++)
{
worksheet.Cells[r, i] = ds.Tables[x].Columns[i - 1].Caption;
}
for (int i = 0; i < ds.Tables[x].Rows.Count; i++)
{
for (int j = 0; j < ds.Tables[x].Columns.Count; j++)
{
worksheet.Cells[i + t, j + 1] = ds.Tables[x].Rows[i]
[j].ToString();
}
}
z = ds.Tables[x].Rows.Count + 3;
}
string textPath = "e:\\output.xls";
if (File.Exists(textPath))
{
File.Delete(textPath);
}
workbook.SaveAs(textPath, Type.Missing, Type.Missing, Type.Missing,
Type.Missing,
Type.Missing,
Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);
app.Quit();
}
I'm having an issue with a small personal application I am puttig together. I am loading data into a JDialog. Within the JDialog, I am loading multiple JPanels that each contain a TableLayout. I am dynamically generating the rows from the data that is loaded into the JDialog. Each row contains a JComboBox and a JTextField that are use to make comments about the status of that particular set of data.
The problem I am encountering has to do with the JComboBox components that are being created. When the JDialog window opens, the JComboBox components are visable and working. Although, as soon as I direct the focus to a different type of component, the JComboBox components stop responding to the mouse clicks.
There is no special logic around the JComboBox components. They simply populate with four different string values, which the user should be able to choose from. No ChangeListener is required for this.
Also note, I wrap all the content in a ScrollPane within the JDialog.
The following is the code where I create the JComboBox components within the TableLayout of the JPanel:
private JPanel createColumnPanel() {
int columnCount = report.getColumns().size();
int rowCount = (columnCount * 2) - 1;
SpringLayout layout = new SpringLayout();
JPanel padding = new JPanel(layout);
TitledBorder border = BorderFactory.createTitledBorder(BorderFactory.createEmptyBorder(), "Column Differences: ");
border.setTitleJustification(TitledBorder.LEFT);
double[] columns = new double[] {3, 75, 3, 175, 3, 150, 3, 100, 3, 125};
double[] rows = new double[rowCount];
for(int i = 0; i < rowCount; i++) {
rows[i] = 20;
if (i + 1 < rowCount)
rows[i + 1] = 5;
i++;
}
double size[][] = {columns, rows};
JPanel panel = new JPanel(new TableLayout(size));
columnStatus = new ArrayList<JComboBox<String>>();
for(int i = 0; i < columnCount; i++) {
JComboBox<String> comboBox = new JComboBox<String>(statusLiterals);
comboBox.setEnabled(true);
columnStatus.add(comboBox);
}
for (int i = 0; i < columnCount; i++) {
panel.add(new JLabel(report.getColumns().get(i).getSchema().toString()), 1 + ", " + (i * 2));
panel.add(new JLabel(report.getColumns().get(i).getTableName()), 3 + ", " + (i * 2));
panel.add(new JLabel(report.getColumns().get(i).getColumnName()), 5 + ", " + (i * 2));
panel.add(columnStatus.get(i), 7 + ", " + (i * 2));
panel.add(new JTextField(report.getColumns().get(i).getRequestor()), 9 + ", " + (i * 2));
}
panel.setBorder(border);
panel.setVisible(true);

and this is the function for button click :

string ert = TextBox2.Text;
string filename = #"D:\\ExcelOpenXmlWithImageAndStyles.xlsx";
CreateExcelOpen exp = new CreateExcelOpen();
exp.BuildWorkbook1(filename);
}
here are my requirements:
1.I need to pass the values of two textboxes to the two cells(which now contain values 12334 and 124515).
2. The heading column does not adjust itself to accomodate the values which i have provided(Retail customer group etc).Please suggest the
modifications required in this class to enable the autofit.
Thank you.
In Your CreateContent method you have hard coded values like:
c.CellValue = new CellValue("12334");
change it with values of text boxes that you want to show.
for setting width of headers, you will have to add columns along with Cells as you need columns to define the width, following article will be of some help for you:
http://catalog.codeproject.com/script/Articles/ArticleVersion.aspx?aid=371203&av=543408
I wrote my own export to Excel writer. It is fast and allows for substantial formatting of the cells. You can review it at
https://openxmlexporttoexcel.codeplex.com/
I hope it helps.
I've spent a lot of time googling OpenXml related questions.
I finally found a solution to my problems by combining OpenXml features with Excel VBA.
So,
I have Excel - macro enabled file (xlsm) as template for my project.
Whatever logic is hard to implement in OpenXml I moved to VBA.
For AutoFit for example it is as easy as:
Sub Workbook_Open()
ActiveSheet.Columns.AutoFit
End Sub
Hope it may help.
