Its this one ... "ByteConverter cannot convert from System.Int32." NotSupportedException was unhandled.
This happens when i select a combobox item and go to next control on the form.
Many thanks,

This thread seems to be getting lost. Try stepping through the code in the debugger (put a breakpoint where the exception occurs), and capture all values. Then post those values, the exception, and the code around the exception, so people can see everything that is involved with the problem in one message. txtspeak is the realm of 9 year old children, not developers.

I've tried at least three free custom controls, and either they make very broad assumptions, or are so poorly designed and documented as to be unusable.
I've tried SuperList, ObjectListView, and one other that I don't recall the name of.
I need the following features (in order of importance, but first three are must-haves):
0) The ability to put one *or more* images in a given cell along with text
1) Sorting on any column
2) Supports grouping
3) Multi-line items
4) Alternate row colors
Can anyone steer me to something usable (and free)?.45 ACP - because shooting twice is just silly ----- "Why don't you tie a kerosene-soaked rag around your ankles so the ants won't climb up and eat your candy ass..." - Dale Earnhardt, 1997 ----- "The staggering layers of obscenity in your statement make it a work of art on so many levels." - J.

Hey,
I want to create a .xlsx file based on data from a grid.
My problem: I have values like 01234 (starts with zero) exporting them make 1234 ... so, how can I export it with right format?
I fill the file with:
if (Excelpfad == "")
return false;
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
Microsoft.Office.Interop.Excel.Workbook newWorkbook = excelApp.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
Microsoft.Office.Interop.Excel.Sheets excelSheets = newWorkbook.Worksheets;
string currentSheet = "Tabelle1";
Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)excelSheets.get_Item(currentSheet);
for (int i = 0; i < UsingGrid.Cols; i++)
{
for (int j = 0; j < UsingGrid.Rows; j++)
{
worksheet.Cells[j + 1, i + 1] = Convert.ToString(UsingGrid[j, i]);
}
}
for (int iExcel = 0; iExcel < UsingGrid.Cols; iExcel++)
{
((Microsoft.Office.Interop.Excel.Range)worksheet.Columns[iExcel + 1, t]).ColumnWidth = UsingGrid.get_ColWidth(iExcel) * 0.13171875;
}
if (Excelpfad.Substring(Excelpfad.LastIndexOf(".")) == ".xls")
worksheet.SaveAs(Excelpfad, Microsoft.Office.Interop.Excel.XlFileFormat.xlExcel8, t, t, t, t, t, t, t, t);
else if (Excelpfad.Substring(Excelpfad.LastIndexOf(".")) == ".xlsx")
worksheet.SaveAs(Excelpfad, t, t, t, t, t, t, t, t, t);
and another question: how can I close that file correct?
I have:
newWorkbook.Close(true, n, n);
excelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheet);
but the "EXCEL.EXE" process still run
thank you

first question:
something like:
r.NumberFormat = "@";
Note this is language specific(system language and settings).
Best way to do it is record a macro while you set the Format to text and look at the VBA produced and
translate it to C#. This silly article is especially about formatting. And the export is a lot faster than the cell by cell aproach.

Hi,
I am allowing user to select datetime in datetimepicker in "dd/MM/yyyy" format but when it stores in sqlserver 2005 it store as "mm/DD/yyyy", but i want it store as "dd/MM/yyyy" format in SqlServer 2005, how can i do that OR When i filter records, it should be in "dd/MM/yyyy" format ?
Regards,
XYZ

The internal format used to store a date time has nothing to do with how it is serialized as a string. Both SQL and C# have techniques for serializing date/times. In particular, you'll want to look into DATEPART and CONVERT for SQL and ToString and String.Format for C#. The C# DateTime also has several methods that allow you to serialize to different common formats.

Write in SQL Select Query
Select Convert(varchar(10),getdate(),103) Like this will return dd-MM-yyyy
And in C# use .ToString("dd-MM-yyyy");
In grid use DataFormatString Property and make sure HTMLEncode="False" set in That columnBest Regards,

I already know how to do that... you might want to reply to the OP to tell him/her what you've told me. Though, to be honest, I think I gave him/her enough information already.

You are basically asking the same question again. What have you tried? What API are you using to interact with video? What is your actual problem? Be more specific.

I am basically gathering information yet. As i told you that i dont have any idea of multimedia in C#. So i need the full information. Googling lead me to DirectShow .net library. Is this library enough for my requirements. What i need is:
We have a in-house channels of Movies. We want to play ads in that channel. The ads can be a:
1) standalone ad
2) A strip (like news headlines in various channels)
3) An L-shaped ad (like shown in some sports channels)
these ads will be in swf/avi/wmv/mp4 etc formats.
In addition, we want to have a scheduler for playing movies(basically a queue)/ads(managed on timely based)/Logo(for the in-house channel i.e an image or an animated image or video format).
These are the basic requirements for the project.
I want to learn multimedia coding in c#, so need a kind response.

Thanks for reply.
What mean of "a third party library" ?
Thanks.We are haven't bug,just temporarily undecided problems.
|
|
|
|
|
It means that library was created by other people/company. Some phones uses JAVA
|
|
|
|
|
I develop apps for the iPhone. I have to use Apples iPhone SDK to create and compile the application. Apple does not support C# but instead use Xcode for iPhone apps. So in this example, the third-party library would be the iPhone SDK.
I hope this helps.
