Hello,
I have a user control which contains a button that shows a form under my user control. The user controls size varies so I change the size of the form and its controls - a panel and checkedlistbox and than call the Show method. Before the call the Size properties for the form and its controls are correct, but after the call the width of the form is set to 112 pxl. If the form is bigger there is no such problem, its the smaller sizes that cause the problem. Any ideas what could be the reason and how to solve the problem?

The commons things to forget when adding controls are
- calling control.Show()
- actually adding the control with tabPage.Controls.Add(control)
- moving and sizing the controls so that all of them can be seen
If your app does those three steps, please post the code that adds the controls. I really cannot read from your thoughts what's missing.

Hello,
Is it possible in VS.NET to make a separate dll's for images alone. What I want to do is to change images in a C# program by changing the image dll's, so you dont have to open VS.NET to do that. (kinda like changing languages in a C# program).

Hello,
I have a user control with a panel which contains a checkedlistbox on it. I'm changing the controls sizes in the mousemove event, the problem is that it starts flickering. I have another user control which has a treeview instead of checkedlistbox and there is no such problem. So is the problem in the checkedlistbox control ? I used SetStyles with UserPaint, DoubleBuffer, AllPaintingInWmPaint for the user control but it didn't help. Any suggestions how to solve the problem?
Thanks

It seems flicker problem is a big disadvantage of C#, I developed a drawing tool using C#, It flicked terribly when drawing more figures. And I also use DoubleBuffer, AllPaintingInWmPaint. Its effect is not so good.

Hi,
I have another problem. The user control I'm using is shown in a grid cell. When I click the cell I set the sizes of the panel, checkedlistbox and the form so they fit in the cell. The strange thing is when I show the form if it is less than 112pxl it is set to them. I can't think what can cause this problem . Any ideas?

Dear all,
Does anyone has sample source code for audio wave file output through a DAC to speaker. 
Please advise.
Wave file -> saved into SRAM/flash then memory is retrieved from a microcontroller and output to a DAC for conversions. After converting from digital to analog format, it will be output to speaker.
Please advise.Thanks.

hi guys,
i was wondering if anyone knows how to extract the file summary properties of a pdf document in .NET environment. Similar to right clicking a file then choosing properties and then selecting the summary tab.
Now microsoft does provide a dll called dsofile.dll for .net. But it does not read pdf file properties because its not an ole document. I have come across something called IPropertyStorage but this is also used in the dsofile.dll so thats no help to me unless i have misunderstood it.
Having given upon on that front, I ventured into looking up the adobe acrobat sdk 7. In the adobe acrobat sdk 7 and it mentions something about containing within the pdf file a metadata descriptor. This metadata is encapsulated in the document dictionary information within the pdf.
I have tried loading a few of the COM objects that comes with adobe acrobat reader but couldnt find anything relevant to extact with metadata information. Unless i have overlooked something, have i ?
Anyone have any ideas as how one could extract this meta data information using .net ?
At the moment i am totally stuck so i would very much appreciate it if anyone could throw any other ideas as how i can read pdf properties.
thanks

All of this code is IN THE SAME PROJECT. What am I doing wrong?
WinForm -> I have created an event handler for my "Add" button control.
I then added a generic class to the project "MyClass" with a constructor that takes a (private) int x with Set and Get properties.
OnButtonAdd
{
WHAT DO I NEET TO DO TO INSTANTIATE "MyClass" so the Win Form "sees" it??
}
Namespace problem? Parameter args wrong?
thanks in advance...

Does it not compile, or is intellisense just failing ? Have you typed in the full namespace to the class, to see what happens ? I take it you mean the int that goes in gets put onto a private variable with get and set properties ?
The WinForm won't 'see' the class instance for any longer than this method call, unless you're passing it's instance into an ArrayList or something.
