So use flags correctly.

Use CREATE_ALWAYS then.

Hi,
I read somewhere that its a bad idea to pass CString between threads but I wondered if it was OK if the threads were only reading the CString and not changing it.
I have a global CString initialised by the main thread at start-up but many other threads need to be able to read it while the application is running and I wonderd if this was OK.
Any help would be appreciated.

Reading should be okay. Can you guarantee that the threads will be only reading from the variable and not writing to it. Is it a const variable.

Thanks for the reply. I am not sure that I can make it a const variable otherwise I dont see how I could set it initially (at run time). I guess I could use a const "Get" method to return the string. That should enforce read only access.
Thanks again

A CString object in any form is not thread-safe.

The same rules apply to any object shared between threads.
Reading a CString is probably safe, and probably always will be, BUT...
CString is a class, and its implementation is hidden from you. You have no way of knowing
if the underlying implementation moves the string around in memory so theoretically even read
access should be synchronized between threads.
Again, if you look at the CStringT class it's safe. The underlying implementation could change
at any time though. Probably won't, but...just something to think about before assuming all
read operations are safe on objects.

What is the animation you are talking about? Are we expected to guess that? Is that a GIF or a Flash movie or what exactly is it?

The following two articles are relatively simple and would be helpful to add GIF animation to your project.

I need to display the GIF file or any of the animation files in the Splash Screen and not over the dialog box itself.. sorry..

There is no such resource called as 'Splash Screen'. It essentially must be a window and the article shows you how to display a GIF image. Can you give me any clue of what your splash screen is? In my opinion it must be a dialog box resource, without title bar. You've either got your graphics on that dialog or you would be loading it later from your program.

Hi,
I have used the code that have been described in CSplashScreenEx : a non rectangular splash screen class with Alpha blending - By John O'Byrne.
Here the code,
CSplashScreenEx *pSplash=new CSplashScreenEx();
pSplash->Create(this,"Welcome to Caliber Infotech",0,CSS_FADE |
CSS_CENTERSCREEN | CSS_SHADOW);
pSplash->SetBitmap(IDB_SPLASH,255,0,255);
pSplash->Show();
Sleep(1500);
CAnimateCtrl* pSplashsmall = new CAnimateCtrl();
pSplashsmall -> Create(WS_VISIBLE | ACS_CENTER | ACS_TRANSPARENT, CRect(125,60,291,104), pSplash, ID_ANIMATION);
//Here the code for Opening and closing the avi files have to be inserted
pSplash->Hide();
so i am trying to use CAnimateCtrl class to accomplish the task. Now am trying to Open the avi file.
With Regards,
Sangeetha.

avi file or a GIF? You said it was a GIF.
The class that you are using allows you to associate the splash screen with a bitmap only and not a GIF.
PS: The portion of the code you've posted has got nothing to do with your query.

Hi,
I need to display something that can be seen animated to the user. Thats why i selected CAnimateCtrl class. Since this is new to me, i didnt have any idea over, and hence i told it is GIF. Now i studied somewhat, and hence understood that metafiles, avi, and GIF all can be used. My need is, i need to display a Splash Screen with some animations. Sorry for my blabbering.
With Regards,
Sangeetha.

Hi Whitesky,
I used the CAnimateCtrl class, opened and played the avi files. But some avi files are not getting displayed. What may be the reason for that..? Please suggest me some ideas.
With Regards,
Sangeetha.
