Hello there!
I am trying to create an export for DataGrids and Bitmaps into Excel.
To do this, I created an overloaded function with the ability of exporting into a specific worksheet.
Right at the moment, the function looks a little like this:
public void datagrid(GridTab gt_toexport, int sheetnr)<br />
{<br />
Excel.ApplicationClass excel = new ApplicationClass();<br />
Excel.Workbook excelWorkbook;<br />
<br />
<br />
if (File.Exists(target))<br />
{<br />
excelWorkbook = excel.Workbooks.Open(target,<br />
0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",<br />
true, false, 0, true, false, false);<br />
}<br />
else<br />
{ <br />
excelWorkbook = excel.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);<br />
}<br />
<br />
Excel.Sheets excelSheets = excelWorkbook.Worksheets;<br />
<br />
Excel.Worksheet excelWorksheet = (Excel.Worksheet)excelSheets.Add(null, excelSheets.Count, 1, true);<br />
<br />
System.Data.DataTable table = gt_toexport.Table;<br />
<br />
<br />
excel.Save(target);<br />
}
All the things I marked with ***'s are things I am not sure about.. or dont actually work 
Another thing is ... I dont know how to export a Bitmap object or an jpeg File into an excelsheet ... ;(
Would be great if you could help me out 
Big TIA

Hi, im new to C# and i need some help printing HTML files programmatically.
Currenly i have created a windows application (C#), that scans a specified directory. For the files it should print. I am able to print the HTML files currently to any printer that is specified (without prompting at all). I use the Windows API SetDefaultPrinter to set the printer to which IE Must print.
The program scans the HTML files for this information.
Currenly i am also able to set the Headers,Footers,Margins by editing the registry.
But i need some help with setting the PaperSize,Copies (Or i could just loop),Orientation
Please let me know thanx.

I've been working for days on a project that creates a BAND OBJECT(BHO)in IE. This BAND has a button which when pressed finds a text box in the current HTML page, fills it in, then finds a button and clicks it to submit the page changes.
So far, I've found a terrific C# template that allows you to create a Band Object in IE. http://www.codeproject.com/csharp/dotnetbandobjects.asp
I've commented this code extensively and have done some Regional grouping to make the code clearer. Let me know if you'd like to see it.
Anyways, so I'm down to the part where I'm trying to access the HTML page. From my research, I've found that AxShDocVw, SHDocVw, mshtml references are needed to work with the browswer. Honestly, that's all the solid information I know. How do I take advantage of these references to access the browser and it's DOM?
I'm really pressed for time, so I'd appreciate your help...A LOT!
Thanks,
Dustin Lyday

Hi,
am sure this question or one very much like it has been asked already by someone else but I can't find the thread so sorry for asking it again.
I have a screen with 1 listbox and 1 datagrid. The listbox is populated (via a stored procedure) with users.
I have another stored procedure which displays user info depending on whether 1 user is selected or all users are selected. What I need is to be able to select various users and then display the info.
How do I loop through the listbox?
Sorry again for re-asking old questions, please point me in the direction of the old thread if thats easier.
Really basic code sample below, I know the loop code has to sit in the 'else' section somehow.
private void btnRefresh_Click(object sender, System.EventArgs e)
{
if(chkSelectAll.Checked == true)
{
AllScannerCount();
}
else
{
SelectedScannerCount();
}
}
Thanks in advance

I wrote a program that would change edi to xml.
Anyway the problem is to be able run the program from a network drive.
I keep getting Security Exception errors, regardless of how much I tried to play with the Security class (FileIOPermission or PermissionSet ....)
My question is:
Is there a way to request for the permission without using the .NET configuration or caspol.exe?
Thank you so much.. please help if you can

No. The network is not a trusted source of executeable code. The application can't get permissions when the code is not trusted in the first place. You MUST configure CAS to allow the appropriate permissions for code running from a remote location.

Hi,
I am writing an email client application in C#. Do you know if there is any .net Component that I can use to show the email message body..(since sometimes the message contains html)
|

Yes, use the Microsoft web browser control (put %system32%\shdocvw.dll in your Visual Studio toolbox, then drop it on your form). For advanced manipulation of the Microsoft web browser control, you may also need to add a reference to %program files%\microsoft.net\primary interop assemblies\Micrsoft.mshtml.dll

public enum Colors {Green, Red, Blue}<br />
How do I programatically know how many items are in that enum ? I need to create an array with the size of how many items are in that enum. For example when I have two items in the enum (Green, Blue), I have an array of size 2 (int[2]).
Regards,
Desmond

This will do it.
Enum.GetValues(typeof([type name of your enum])).Length;
The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' ('I found it!') but 'That's funny...’
|
|

Very simple (if you know how, of course  ):
Enum.GetValues(typeof(Colors)).Length GetValues() already returns an array, so perhaps you can use this one directly instead of creating one yourself.

I have a customized Print Preview dialog made of a Print Preview control.
When I increase zoom property, the document inside it gets enlarged and two scroll bars appear. But when I scroll down with Vertical scroll bar, it doesn't go till the bottom and bounce back upwords if I resize(enlarge) the Dialog it self. It doesn't show the bottom of the document in any case.
More over when the dialog is compressed and the document in side the preview control is not 100 % visible widthwise, the expected horizontal scroll doesn't appear.
What is the reason for such behavior?
Please guide

hi friends.
i am facing a problem.
i want to display some text in a multilined texebox. actually its a text box, displaying some status. I want to show different color text for some perticular status. i tried using the color property of the textbox, but it changes the color of the entire box.
please help.

Get a textbox that supports multiple colours.
Either that, or I remember doing this years back in vb4 (with extras) using subclassing to do the job. If i remember rightly i trapped the paint event, got the position for the line i wanted to colour etc and printed the new coloured text directly over the exiting one in the listbox. This worked surprisingly well especially since I only did it to piss off a mate who said making colour listboxes was the only thing he couldn't do

Have a look at the RichTextBox control coming with the framework.
