Which means what exactly ? Please be precise in your answer (e.g. if you have a compilation error, supply the error message).

Ok
I'm debugging the program that uses those functions mentioned earlier. I've attached a checkpoint on TDriverLayer_RegisterDevice function body and it doesn't stop there. So i'm thinking that when running my program, that function isn't even being considered. But we're calling it from (*FktFunction)(TDriverLayer_RegisterDevice, TSMAData_OnNewEvent); ?! That's the problem...
Best Regards.

Possibly you should post more code.

Declaration:
void (*FktFunction)(int (*RegistFuncPtr)(struct TDevice * newdev), TOnDriverEvent eventcallback);
Calling:
(*FktFunction)(TDriverLayer_RegisterDevice, TSMAData_OnNewEvent);
Register Device Function Definition:
int TDriverLayer_RegisterDevice(struct TDevice * newdev)
{
struct TDevice * CurDev;
foreach(&DeviceBase, CurDev)
{
if (strcmp(newdev->cName, CurDev->cName) == 0)
{
return PHY_ERROR_DEV_TWICE;
}
}
newdev->DriverID = NextUniqueDriverID++;
ADDTAIL(&DeviceBase, &newdev->Node);
return PHY_OK;
}

foreach is earlier defined as a function to search any kind of object we need to find in a list.
FktFunction pointer is assigned to
int TDriverLayer_RegisterDevice(struct TDevice * newdev)

OK.

Nope: RegistFuncPtr points to TDriverLayer_RegisterDevice.

i have 2 files a.cpp and b.cpp
i want to use the variable (suppose int x) which is public in .cpp1 in .cpp2(means i want to asign the value in d=x in cpp2).then how i can acess the value x in cpp2  .
remember
cpp2 is a class
cpp1 is cpp1 is a class derived publilicly from ccdialog
|

If x is a member of the cpp1 class (what a bad name for a class) the you must have access to an instance of the cpp1 class in order to gain access to x.

Hi,
why do we need to use CreateCompatibleDC to create a DC even though we can create a Dc using CreateDC?
Regards,
KDevloper
|
|

|
|
Performance!!!
BitBlt between compatible DC as many TIMES faster than otherwise.
|
|
|
|

They are two different functions that create different kinds of DCs.
You don't "need" to use CreateCompatibleDC. You use it when you need
a memory DC compatible with an existing DC.
It's not the same as CreateDC.

if u can't then don't ....

Now excuse me sir!
Have a think about it before you ask such foolish and useless questions.
What bloody button code? Which bloody article?
What was the response you got when you asked how to use the code on the page you downloaded it from? Is there not an example application that may be obtained from the article page?
Like you said - if you can't ask a reasonable & sensible question, then just don't!

I am using COXTreeCtrl from the Ultimate Toolbox in my code. I have a parent tree and under it, 4000 child items with unique IDs. When I click on the "ID" column for this tree, it is calling a CALLBCK procedure to sort these 4000 items.
But the real problem is THE TIME IT IS TAKING to sort 4000 items -- More than 5 Min.
Is there any way I could sort the column, which will take less time to sort??
|
|
|
|
|
Does it draw the tree during the sort process? I mean, do you see as items get swapped? Becuase you can speed up things a lot if you disable the repainting of the control while the process is running. You can try using SetRedraw(FALSE) just before you begin the sort and SetRedraw(TRUE) and RedrawWindow(NULL), after it. I hope that can help some.
|

|

No, the items are not getting swapped. I think it will draw the tree items only after completing the sorting process. And drawing of 4000 items is taking approximately 10 Sec of time.
I also tried SetRedraw() function while sorting but could not see any improvement.
While debugging, I observed that for sorting 4000 items, it is entering into callback procedure >100000 times.
Is there any way to sort the list using other than callback method??

Hi all,

#include <locale><br />
The error message is,

Can someone tell me what's going on.
I appreciate your help all the time...

I believe this means that you are linking with both the Release and Debug C Run-Time Libraries[^]. Check your project settings for each project in the solution and choose one or the other but not both.

Hi All
how can i open a application through shortcut key?My application is running in hidden mode.Plz help me
|
|
|
|
|
You mean you are able to intercept the shortcut key and now you want to execute your application. then you can use ShellExecute(/*parameters*/) or CreateProcess(/*parameters*/) depending upon your needs
Some things seem HARD to do, until we know how to do them.
