I am trying to write a function that copies a jpg or a gif to the clipboard, when I pass the path to it.
ie
jpgclip("C:\test.jpg")
Can anybody help me?
Regards
Paul

Have you looked at SetClipboardData()?

Yes I have looked at this function, but could use a few pointers on how to use it. I know I can send a bmp to the clipboard with this, but is there anything I need to know when sending jpg or gif?

Hi Everybody
I am doing a project in image processing using MFC.
Could some one tell how to save a bitmap (1 bit,4,8,24 bits respectively).
Thanks in advance.

No 16 bit ?
If you're using GDI+, read my articles on the subject. Otherwise, I guess either save to bitmap only ( the format is well documented and simple ), or find some other library to use.

Hi I am doing a project in image processing using MFC. GetBitmapBits() stores the pixel value in a BYTE array. It works fine with 8 bits bitmap, but when working with 4 bits bitmap, it combines 2 pixel values and stores in the BYTE array.
How to overcome this problem

Use && and || to combine and mask values, instead of + or =. For example, FF && F0 == F0. If you take an 8 bit number and set it to equal itself && 15, you get only the low four bits, && 240 gives you the high four. In that way, you can set one pixel to zero. Then if you want to set the pixel in the low four bits, you just put oldVal || newval, that copies it in. to copy into the high four, do this: oldval || ( newVal << 4). this shifts the values up four bits first. To just set two pixels do this (pixelLeft << 4) + pixelRight. You can use plus here, because you're replacing both values.

i try to change the source of a browser helper object, which makes some strange things (like opening google, if i want to open a .js file  )
my question (because i don't really know much about helper objects) how can i debug the object?
it is visible as an Add on in Inernet Explorer
and when i try to debug the bho visual studio .net asks which application holds the debug information
i tried using Internet Explorer, but didn't work
the helper object is a dll
maybe the question should be how to debug a dll?
thx@ll

Is your name really Candy, or did you just think that was a name that would get guys to help ? :P
Seriously, the web is full of help, there is at least one article on this site, and your textbooks should be loaded with info also. However, by all means if you read your textbook and you're stuck on *specific* things, feel free to ask, whatever your name is....

How to remove close button from window?I just want maximize and minimize buttons on window.if it is not possible to remove close button can i make it disable?
I have tried it using WS_MAXIMIZEBOX and WS_MINIMIZEBOX .But it is not working.

Hello,
I don't think that there is an easy way to remove the close button, since it's part of the system menu. You can use GetSystemMenu() to disable it..
You can also remove the entire title bar.
But please tell me why you want to remove the close button? Users will be really annoyed by this!

Try this: GetSystemMenu(FALSE)->EnableMenuItem(SC_CLOSE, FALSE);

Hi,
I've written a windows service to parse files.It uses the FileSystemWatcher class in C# to sniff a folder for particular type of files. But when the files were being processed, i repeatedly get the error "The process cannot access the file "AAA" because it is being used by another process". To overcome this problem, i added the following. lines of code
<br />
<br />
public bool ParseEnvFile(string strFilePath)<br />
{<br />
try<br />
{<br />
using(FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read, FileShare.Read))<br />
{<br />
fs.Close();<br />
m_nReadAttempts = 0;<br />
}<br />
}<br />
catch(IOException ex)<br />
{<br />
if(m_nReadAttempts < 3)<br />
{<br />
Thread.Sleep(2000);<br />
m_nReadAttempts++;<br />
return ParseEnvFile(strFilePath);<br />
}<br />
else<br />
{<br />
throw ex;<br />
}<br />
}<br />
.....<br />
}<br />
But even this did not solve the problem. The exception still kept coming, though less frequently.
So I was forced to add a Timer event(runs every 5 mins) that would pick up all the files that were left over because of the exception.
Now, my problem is this:
When a file gets created in the folder, sometimes both the OnFileCreated event and the timer event try to access the file at the same time. Within my
service, I'm required to open the file in write mode and update some contents. I find that at times the file that gets created ends up as a 0KB file (Note: when it initially got created the file had some content in it)!!!!
Any ideas on why this happens?
Thanks for any help in resolving this problem.

hiho@ll
i'm using Visual Studio .Net
1. i have compiled/runned/debugged many "self-made" projects and some projects from codeproject.com
2. i got the source of a programm which i want to debug, which seems to be programmed using visual studio 6.0
3. if i try to debug the prog i get the following error:
"
Unable to start debugging.
Unable to start program "c:\program files\internet explorer\iexplore.exe"
Das System kann die angegebene Datei nicht finden.
"
4. it seems that .net tries to debug using iexplore.exe in program files folder
but my iexplore.exe is in programme\Internet Explorer\...
question: how can i change the debug options for this project that .Net knows that iexplore.exe is not in program files\ but in programme\ folder?
thx@ll
