Hi, all,
In WinForms with C#, a TableLayoutPanel custom control with, saying, 10 rows and 5 columns being designed in designer window. NumberOfRows was coded as a property of this custom control. I wish to change this property value and set it as a new RowCount of the TableLayoutPanel mentioned above, before the custom control running InitializeComponent(). Is this possible? I have tried to do it with a method in the SET of that property as below:
private void OnNumberOfRowsChanged()
{
tableLayoutPanel1.RowCount = numberOfRows;
}
and it didn't work while I change the value of NumberOfRows property, and set a breakpoint in the constructor method of that custom control, the RowCount remains as 10.
Btw, I tried to use tableLayoutPanel1.RowStyles.Remove() and tableLayoutPanel1.RowStyles.RemoveAt(index) as well, neither of these two works as well...
Any Idea?
Your kind help is so much appreciated!!

I can't for the life of me work out what you're talking about, or what your problem is. What is 'pop up for windows' ?

My guess is he wants OpenFileDialog.

Does your menu have an Open File option in the media player or at least a button to do so? If not add one.
Then add OpenFileDialog and have it fire when needed.

Hai friends
I've been trying to convert files (office) to pdf.
For that i installed SaveAsPDFandXPS.exe from Microsoft and iam using Office 2007, it works in office 2007 but creates problem in a machine with office 2003.
object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;
the code above is not supported in office 03 but s supported in 07.
Is there any way by which i can convert the file to pdf in office 03.
Thanks in advance for all your helping hands..

You probably need to buy a library that is more universally supported instead of using what you're using.

From Word ? I'm not sure, I think I've seen one, it was quite expensive, and I forget the name.

If you install a pdf printer such as PDFcreator, you could simply open the word doc, then print it. Though you can print programatically in such a way as to avoid the print dialog boxes, you'll still be faced with PDFCreator's 'save as' dialog box. I don't know if it is practical to automate the 'save as' dialog interation in your situation; though, if you are just trying to convert a few hundred files or will always use this in a manual enviornment, this should solve your problem.
If you take this approach and can't/don't automate the 'save as' dialog interaction, I recommend putting the target file name and path in the clipboard so that you only 'ctrl-c' the file name and click save.
Hope this helps

There is a dll file in a program I use that contains product information for the program to use. I was wondering is there any way I can gain access to the data in the dll file in a C# project. The file dosent contain anything that I shouldnt have, it is just catalogue information.
I have never accessed data from a dll file before and I dont know where to start. I can access the data using Resource hacker but when I tried to add it as a reference to my C# project in Visual studio it gave an error saying that the file isnt a valid com component. I am sure that this is obvious to anyone that has a clue about this, but as you can tell i dont.
Can anyone help me access the data in the dll file?

What DLL is that? A managed one or a native DLL?
Best wishes,

dont really know the difference. All I know is that it is packaged with the program and it contains catalogue data .

If you can't import it into a .NET app, then it probably is neither COM nor .NET, meaning it's just a bog standard dll, and my answer below applies.

If it's not a COM component, then you can try to reference it as a standard .NET dll. If that doesn't work, then it's not written in .NET, and .NET is the only way you could use reflection to read the contents of the dll. Even if it was COM, you still couldn't read the contents. Your best bet in that case, is to use a hex editor to see if what you want is sitting in there in an unencrypted state.

Hello friends,
How do we get the position(top,left,height,width) of the child window control embedded in another window. The problem that I need to solve can be described below.
1)In skype when we have the video call we can see the video of the calling party in the window embedded in the main messenger window
2)I want to capture the video of the embedded video window of the main messenger window
3)From the process Skype.exe we can get the handle of the Skype main window and from that handle of the main window I want to find out the top,left and height,width of the embedded video window of the main messenger window. How I can achieve this? Any suggestions or alternate ways to do this?
Thanks in Advance

You can iterate over the child windows using C APIs, yes. You can use p/invoke to do it from C#. However, it sounds ugly to me. I am not sure how you'll work out what window you want. There's an API that gives you the window at a point, perhaps you need to get the user to click on the video window ?
