I have placed the Sleep in the progress callback function as: bool DataCryptMain::ProgressBarProc(PRBDATA *prbdata) { ... Notify_Progress_GUI(NOTIFY_PROGRESS_RUNNING, NULL, (LPARAM)_prbdata); Sleep(1); } You said: "Try to decrease the number of messages sent to your GUI, for example, send only every 10th status report, or check when you sent the last report and if a given amount of time (like,for exaple 100 ms) didn't ellapse yet then skip sending the message, OR perform the percentage calculation in your thread and only send a message towards the GUI if the new percentage is different from the previous one, this should reduce the messages heading towards the GUI to not more than around a 100 messages per run, which shouldn't be too much, unless you are some very low end hardware" All these i'll try them by using PostMessage or SendMessage?

Dennis L wrote: Is it ok to use EnumChildWindows? It depends on your requirement. If you want to modify less number of controls you can add the control variables for these controls and use them. EnumChildWindows will enumerate all the child controls which might not be efficient if your dialog has huge number of controls and you need to alter only 4-5. BTW: Use some relevant title for your post.. "Hi All" does not relate to your query in anyway. Regards, Sandip.

one suggestion (Off Topic) : Please use code block tags for posting code. Also indent the code so it is readable. Now about the topic. You can use forward declaration to solve your problem. Check this link for example : Forward declaration[^] Regards, Sandip.

There's no item associated with the NM_CLICK notification. NM_CLICK (treeview): "Notifies the parent window of a tree-view control that the user has clicked the left mouse button within the control" What are you trying to do? Which item do you expect to get when the user clicks the control? Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Well, what's being missed is that s0,s1 and s2 are char Arrays of 1,2 and 1 byte respectively, and NOT poiners! Why are they being displayed as DWORD. What byte packing is used. Unless if you have a constructor SOME(), in which you specifically initialise the structure, you should not rely on the content of the structure because it is unpredictable. The DEBUG version of the compiler tries to pad uninitialised and deleted structures with garbage in an attempt to make your code blow if you by mistake forget to initialise, or attempt to refer to de-allocated data. The Release version is by no means as friendly, in that it does none of these things. If your code works while referring to data outside their validity scope, you create a timebomb which at some time in the future will cause unpredictable and mysterious crashes. I note that you read the structure after deallocation, This mere read could lead to an invalid memory access crash. (ever tried to read a NULL pointer?) Regards, :) Bram van Kampen

Watch out for memory alignment issues if you are going to use these keys (I'm assume they will be crypto keys) with raw memory access. You can change the way the object is laid out in memory with the #pragma pack directive. It may not be a problem though, depends on how you'll use your struct (Actually it would show not so great design if you'd need this, but there may be performance reasons).

I was recently looking into this because I've been implementing exception handling myself, as opposed to just using it, ( based on porting a VC6 OSS implementation). There's a set of matching rules that decide whether a particular catch handler matches a particular thrown exception. The more I looked into how to implement this the more complex I realised it is. Added to which the flags in the underlying Windows (and VC++ generated code ) exception information don't seem adequate to accurately differentiate between for example a reference to a type and a reference to a pointer type. On the basis that I could find no documentation on these rules, maybe they're buried in an appendix of the C++ spec somewhere, I determined to advise extreme caution when throwing anything other than a straight forward pointer. Plain pointers are clearly flagged in the built in data structures and can definitely be caught reliably. I need to do a good deal more investigation, and ideally get hold of the formal rules, to determine if VC++ does indeed generate enough information to fully implement them and whether MSs own exception system has any holes in this area which I strongly suspect it might. I have stuggled in the past to get catch handlers to match with anything other than very simple thrown types and now I think I know why.

Surely this is work that you will create - it's valid for your teacher to mark it, and maybe keep confidential copies for reference in case someone challenges her marks - but why does she have a right to give your work to the world? If *you* allowed it to be published to the world, then great. I've written some articles here, and am happy to give back to the greater community. But I'd be peeved if I had no choice about it. Would you fail if you handed in the code with "Copyright Dennis L, not GPL, not using GPL, and not to be published without permission" on the top of every page? Saying that, if you use GPL components, their license will infect your code too, I suppose. Iain. Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

Thanks for your reply! I'll check it

First, why would a dialog need access to the mainframe's statusbar ? Second, I think that you need to have a parent window for a child dialog box, me think that win32 needs it ( I'm no expert on win32, so YMMV ). If your dialog box doesn't have a pointer to the mainframe, you will need to keep a global variable to the mainframe ( either a variable, or a global scope function that returns a pointer to the mainframe ) one other way would be to use some kind of messaging mecanism, either with ::SendMessage/::PostMessage or with a Observer/Observable pattern. for example ( high level pseudo code ) CDialog::DoSomethingToMainFrameStatusBar() { CStatusBar* pStatusBar = YourMainFrameManager::GetStatusbar(); } // where YourMainFrameManager is a class that contains pointers to "windows" ( or componements ) of the mainframe ( this class will need to know about the mainframe. CStatusBar* YourMainFrameManager::GetStatusbar() { return pMainFrame->getStatusBar(); } Maximilien Lincourt Your Head A Splode - Strong Bad

if you can get the binary array of the float, you can easily get its hexadecimal representation... group the bits by groups of 4 bits. then use the following : binary <--> hexa 0000 0x0 0001 0x1 ... 1010 0xA ... 1111 0xF then, you have it. see this example : 0b 0010 0101 1101 0110 0x 2 5 D 6 so, the hexadecimal representation of the bits shown is 0x25d6... understand ? [edit] ok, i'm quite sure it won't be that ease for you to get the bit array, so here is a sample for that : float floatToAnalyse = 3.45; //for example char floatBits[32] = ""; //not sure here about how to get the binary representation, but this should work unsigned int uiBitsArray = *((char*)(void*)floatToAnalyse); for (int i = 0; i < 32; i++) { floatBits[0] = (((uiBitsArray >> (31-i)) & 0x00000001) == 1) ? '1' : '0'; } [/edit] TOXCCT >>> GEII power [toxcct][VisualCalc 2.20][VisualCalc 3.0] -- modified at 8:54 Friday 16th December, 2005

You can disable the z-buffer by calling glDisable(GL_DEPTH_TEST), render the text, and re-enable z-buffer.

Hello, What you are doing is asking for trouble! The rule of thumb is: never touch the GUI from your worker thread!!!! If you really need to do this, try the following: use PostMessage() instead of SendMessage(). If you really need to wait for the thread to finish, use MsgWaitForMultipleObjects() instead of WaitForSingleObject(). This way, your app won't freeze because it will process messages.
