Try this code:
<br />
Rectangle rect = Screen.GetWorkingArea(Screen.PrimaryScreen.Bounds);<br />
Best regards, Alexey.

When application start, setting bounds isn't a problem.
But during application life, how application detect working area changes for updating its bounds ?

I think, that probability of changing size or position of application bar is very low, while user running full-screen application.

Ooops what I was trying to say before is that you can't use .NET 2.0 code in visual studio 2003. VS2003 just dosen't work with .NET 2.0

INPUT :
VC++ dll (abcd.dll) has funtion named DecryptString.
Requirement :
i need to create a dotnet project which uses this function in unmanaged dll.
Steps taken
public class CryptoAPI
{
[DllImport("abcd.dll", EntryPoint="#392")]
public static extern string DecryptString(string key,string text);
}
When i access the function in DOTNET
string EncryptedText = CryptoAPI.DecryptString(Key,PlainText);
It works fine couple of times.Some times it throws up an error
"object reference not set to instance of an object".
Can u please help me on this?
Can u tell me if i call the method - 5 times is it loaded 5 times during the runtime?
or only once when i do it for the first time.
for thendral

Maybe you pass to your function null or empty string ?
Try to check this before call.
I use this function: string.IsNullOrEmpty(string)
|
|
|
|
|
I have validated the function before.
The gets passed the unmanaged code as well the unmanaged code returns a value
but the result set is not recieved back in the DOTNET string.
getting me?
string EncryptedText = CryptoAPI.EncryptCString (Key,PlainText);
VC++ implementation()
{
char * EncryptCString (Key,PlainText);
{
AfxMessageBox(Key);
AfxMessageBox(PlainText);
///Code to do manipulatione
AfxMessageBox(encryptedvalue);
return encryptedvalue
}
}
the above code snippet ensure that the values of the parameter are passed correctly to the
unmanaged code and it process and return the value correctly
so the interop is the problem i suppose?
ie) getting it from vc++ to DOTNET ?

Try to set charset in DllImport attribute:
<br />
[DllImport("abcd.dll", CharSet=CharSet.Ansi, EntryPoint="#392")]<br />
public static extern string DecryptString(string key,string text);<br />
And try unmanaged type conversions:
<br />
[DllImport("abcd.dll", EntryPoint="#392")]<br />
public static extern [MarshalAs(UnmanagedType.LPStr)] string DecryptString(string key,string text);<br />
I don't know exactly wich type is char *.
I hope you'll find it changing UnmanagedType.LPStr to other string types from UnmanagedType enum.

I had a similar function that returned a string from a C++ dll. Try declaring a global char array in your dll and then copy the string into the array, as below:
char szReturn[MAX_PATH];<br />
<br />
BOOL APIENTRY DllMain( HANDLE hModule, <br />
DWORD ul_reason_for_call, <br />
LPVOID lpReserved<br />
)<br />
{<br />
return TRUE;<br />
}<br />
<br />
__declspec(dllexport) LPCTSTR Test()<br />
{<br />
<br />
lstrcpy(szReturn,"success!");<br />
return szReturn;<br />
}
Hope that helps

When, if ever, should we force the garbage collection to run??

Different questions - Different posts. If he wrote better subject lines it would work better. Also, if you put in all your questions into one post some people feel reluctant to answer because they don't know the answer to all the questions, or they may feel compelled to answer a post that is beyond their knowledge and give the OP some bad advice.

Normally never. The garbage collection runs when needed and when there is enough unused objects for a collection to be effective. Unless you have a very extreme situation you never have to bother about it.

Everything on this forum is a problem to someone - A subject line of "problem" is absolutely useless. Please read the post at the top of the group by Chris that explains the rules of the foru,.

Why should we not use global variables??

pankajgarg12 wrote: Why should we not use global variables?
Because the code gets hard to follow. If you use global variables you have to know how the entire application is working to know how the global variables are used.

What is the difference b/w class and module??
|
|
|
|
|
Class is an instrument of object oriented programming.
Module is only file. wich can contain classes.
Module can contain several classes.
You'll learn more, after reading book about C# or object oriented programming.

Hello
I've got an idea of a ContextMenu containing special MenuItem's. I've spent the last hours with codeproject, google and a lot of coffee, but I can't find an answer. Perhaps it is very very simple and I'm just too stupid for a clear solution or otherwise it's not possible without writing a complete own implementation of a ContextMenu-class !?
ok, here you are :
I want to develop a 'customMenuItem'-class that can hold 3 or more icons/buttons (play, stop, continue) and a text entry, everything else should act as usual. I want to set a handler to each of the icons/buttons not to the text. I got no prob's with displaying my Items, but I don't found a way to set this kind of hanld or to decide on which button or Icon I've clicked (tryed with some x-positions-attributes).
ok, thanks for reading, but please do not answer with articles like 'how to build menu's with icons', they do not have different handlers for one item or don't analyse any kind of x-position inside.
thx's a lot for reading - sorry for my poor english

Play, pause, continue....
You can dynamicaly uptate one item, because when one of them enabled - other items disabled, why do you want to display them all ?
