Redirect standard input and standard output for the process. Being a Dll makes it more interesting because a dll shouldn't be outputting to standard streams.

Hi Ennis,
How to redirect the standard output? I have been trying to redirect the standard output using Console.SetOut() but it doesn't do much. I am just wondering, what is the standard output in C#? And how to get it?
Thanks

It is done from the Process class which is used to execute executables. Which is why I mentioned my comment about it being odd for a DLL to directly write to STD out.

Hi Ennis,
I did further testing. When I build my application as console C#, the DLL cout writes the output to the console window. But I can't capture it when I build my C# application as form application 
|

In the Project properties, change the <b>Output Type:</b> to <b>Console Application</b> You'll get an additional console window in a Winform application. Ugly for sure but it works.

Hi everybody!
I've got a problem which I've been working on for a few hours now, I've been googling and reading, but I just can't get it right.
Well, let's talk about the main problem; I've got a textfile which contains only one line, like: Nicky:1200
What I want to do is to replace this line with a new one.
Here's what I've got atm:
FileStream file1 = new FileStream(@"1.txt", FileMode.Open, FileAccess.ReadWrite);
StreamWriter writer = new StreamWriter(file1);
writer.Write("Kim:1355");
writer.Close();
But what happens is that the program only appends to the file so when this code has been run the file looks like: Nicky:1200Kim:1355
I appreciate all help I can get on this one!

The easiest way is File.WriteAllText. However, there's file modes you can use to specify if you are appending or creating. I just suspect that FileStream does not offer them.

Thanks a lot!
I used File.WriteAllText though, works fine. Now I'll just have to adjust my application for it.

Any there any free (or < $100) obfuscators that will obfuscate mixed mode assemblies?
Dotfuscator free edition will not. Skater Lite will not and I don't think that the Skater Pro version will either.
|
|
|
|
|
I doubt you can obfuscate mixed mode assemblies.
|
|
|
|
|
I think that the Professional version of Dotfuscator will handle mixed mode assemblies but I think that this version is expensive $$$ (much more than $100).

Hello all
I have a simple form and a picturebox control on it
when I loaded an image(PNG file) by the image property and then
I ran the program
I got a grey-colored picture with the same boundaries of my actual
colored picture.
I tried to change the picture to other pictures (also png) they worked correctly, so the result is, some pictures are viewed correctly and some
are not.
any help?

The picture changes to greyscale ? your code has to be doing that, no way does it happen on it's own.

Hi, thanks for replying
but I know grey-scaled images and that picture
is not.
that picture has no scaling at all, it is just grey.
note: I loaded bmp pics and all is OK.

OK - I misunderstood. Can Paint open the image ? it seems GDI+ cannot.

Yes, Paint and all imaging programs can open it clearly.
you think? I tried the sample on 3 PCs and the result is totally the same.
so should I use JPG instead?
It's a near-to-end commercial application.

Well, I guess so. That's really odd, but for whatever reason, the built in stuff is obviously having trouble.

Hi,
I have a COM object that actually allocate a memory and return a value to the calling function. When I call this COM object in C++, I can just delete the pointer by using delete keyword. But how can I do this in C#? How to free the memory allocated by the COM object?
eg.
In my COM class:
HRESULT __stdcall CTestCOM::getValues(int **arrRetVal)
{
int *pTmp = new int[100];
...
...
...
(*arrRetVal) = pTmp;
return S_OK;
}
Thanks

Btw, I tried to use both Marshal.FreeCoTaskMem() and Marshal.FreeHGlobal() but it crashes with error:
Invalid Address specified to RtlFreeHeap( 00210000, 055AB388 )
Cheers

Why not add a method to the COM class that deletes a pointer that it is provided in a parameter? (Assuming here that .NET doesn't do something nasty to the pointer that makes this impossible/wrong, I'm no expert on COM Interop...)
|
|
|
|
|
Hi Trichards57,
Every good idea. I can pass in the pointer it returns to C# and pass it back to the COM object to delete it.
I have to test it first though.
Thanks for your help
Cheers
