You could try the CArray class in MFC or you can use the vector class in STL.

No. As it stands, it will not compile.

If you are telling this because of the empty [], you are wrong. A few days back, I came to know that an empty [] will return a pointer pointing to a memory of size 1 byte. Thats why I said, it will crash.
Just try..

I just tried it! I can't believe it.

Good to know.

And you're, of course, right.
Thank you for pointing out.

The code you have suggested means that the array elements can only be added in the source code - any dynamic changes in the code are not possible.
If you are wanting to dynamically add array elements at run time, this link may help you solve your problem.

Dynamic arrays means - you are free to allocate any number of members at runtime. But still you should specify the number of items in you dynamic array. The only flexibility is - you could decide the count at runtime where in static arrays, you cannot.
Sunday8PM wrote: MyClass *MyObjects = new MyClass[];
You've to specify the array size.
int ArraySize = 10;
MyClass *MyObjects = new MyClass[ArraySize];
Sunday8PM wrote: I'm worried that since I haven't specified the length of the array before, it might write over something else since it isn't expecting the array to use it.
You cannot instantiate arrays without specifying the size.
Well, you could use stl containers such as std::vector where you'll be free from the array size headache.

Jijo.

I'm going to look into vector's, they sound interesting thanks!
|
|

Sunday8PM wrote: Would the code work?
No, because you have not told new how many MyClass objects to create. Since you do not know this information at the time of creation, perhaps a vector of MyClass objects would work.

Following code should be helpfull;
//... First - allocate class pointer array
MyClass **pArr = new MyClass* [dwClassCount];
//... Second - allocate class objects
for(i=0;i<dwClassCount;i++) pArr[i] = new MyClass;
//... Do the job
//... Release class objects
for(i=0;i<dwClassCount;i++) delete pArr[i];
//... Release class pointer array
delete pArr;

I am trying to merge two icons by drawing one image transparently on another, merging the masks and creting a new icon based on the new bitmap and mask.
The code looks like this:
GetIconInfo(hFirstIcon, &FirstInfo);
GetIconInfo(hSecondIcon, &SecondInfo);
.
dcFirstIcon.CreateCompatibleDC(NULL);
dcSecondMask.CreateCompatibleDC(NULL);
dcSecondIcon.CretaeCompatibleDC(NULL);
dcSecondMask.CreateCompatibleDC(NULL);
.
dcFirstIcon.SelectObject(FirstInfo.hbmColor);
dcFirstMask.SelectObject(FirstInfo.hbmMask);
dcSecondIcon.SelectObject(SecondInfo.hbmColor);
dcSecondMask.SelectObject(SecondInfo.hbmMask);
.
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondIcon, 0, 0, SRCINVERT);
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondMask, 0, 0, SRCAND);
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondIcon, 0, 0, SRCINVERT);
.
...
.
FirstInfo.fIcon = true;
hMergedIcon = CreateIconIndirect(&FirstInfo);
The result is fine, but on certain icons it kills the icon shadow and makes the shadow solid black and ugly. I tried to use TransparentBlt which in those problematic icons leaves the shadow untouched but this function erases the bits where the second icon should show up and make them white.
I guess it is related somehow to XP style icons or to Alpha channel, but am not familiar with those issues and will appreciate some advice here.

It looks like you've conflicting libraries in Release build. Compare Debug settings with Release ones.

Hi,
Did you used Application Wizard to create this project. There is no libraries in the project. So check it out.
Thanks and Regards.

Found a similar thread[^]. It says that this can happen when you mix up the static/dll usage of MFC libraries and CRT libs. Have a look at the thread. Might be useful.

No, not yet I want to make at least debug build complete then, I will work on the Release build.

Hi!
I've created a GUI. This GUI application has one Button. In the click event of this Button, I've run another application. The second application is running as an individual window. What to do if I've to run it inside the GUI application?

Nope it was a post a few days ago I think, about using ShellExecute() to execute an application, but within a dialog. I believe the answer was it couldn't be done
