I believe -according to what i see in the code you gave- you have to select m_bmpBitmap into the memory-dc when you draw the lines.
Btw i see you are using StretchBlt, that will cause problems with drawing those lines, but first try to get it to keep the lines first.

I have a static function in that I have some array members, that function will be called from so many places, I want to know that when ever the process of the function is over means all the member variables will be get released from memory or will Occupy the space.

What kind of array it is ?
|
|
|
|
|
char lbuffer[5000];
sprintf(lbuffer,"Stock in List [%s] Quantiry %d", SymbolList,qty);
but according to me memory is keeps on increasing when ever we call the function it is not reducing after it is completed
|
|
|
|
|
Yes the buffer will be released.

How do you check that ? Are you using some tools to verify that information ?

Yes, You don't need to worry about memory, as its been allocated on stack.
|
|
|
|

How are the arrays declared?
If they're declared as local variables (as shown with localArray below), they will definitely be cleared up, as they're allocated space on the stack, which is tidied up when the function exits.
double SomeFunction(int x)
{
double localArray[] = { 1.0, 2.0, 3.0, 4.0 };
const size_t localArraySize = sizeof localArray / sizeof localArray[0];
return x<localArraySize?localArray[x]:-1.0;
}
|
|

|

The only thing you have to take care in this case, is that if you are allocating memory with new (or new[]), then you should delete it with delete (or delete[]). For the rest, the memory will be automatically released.
|
|
|
|
|
Also don't forget malloc and free (I know, i know, don't use malloc and free in C++ but they CAN be used), and maybe GlobalAlloc and GlobalFree (or LocalAlloc and LocalFree but as far as i know those are no longer different from their Global counterparts)

Hello everyone,
In order to test a ini file (for the read write operation) what are the steps I should make...What I have dome is...
I created an ini file in the current directory, also inside the debug folder.Then I added that to my project workspace....and I wrote the following code
int iResult = GetPrivateProfileInt("extensions","123",555,"info.ini");
cout<<"\n-:"<<iResult;
my ini file content is
[extensions]
123=001100
333 = 9999
444=8888
But its always returning 555
What mistake I might have done?
project is a win32 application
Thanks in advance

Try giving full path of this file. I think it's not in local folder of you application.

If you are running your program from withing Visual Studio (pressing F5 for instance) the working folder is the same folder that has your .vcproj/.sln files - NOT the debug/release folder, so you file would have to exist in the same folder as the .vcproj/.sln.
When you run the program by directly clicking on the .exe file from Windows Explorer, the working folder is initially the same folder with the .exe.
Also, is there some reason that you have blank lines in your .ini file?
Hope that helps.

I have the same file in the debug folder too....
And ya I removed the blank lines and tried....
But the same again...

But what does your changed code look like? If you provide the correct path, the value of iResult will be 1100.

Break points will be enable only if the dll in question is loaded in target executable.
|
|
|
|
|
ok.. but how do I know whick DLL is loaded by .exe, in setting i have given right path.
|
|
|
|
|
You can view the loaded modules using Process Explorer[^] or using the Debug Menu->Modules in the IDE while debugging.
|
|
|
|
|
Try debugging the DLL project, telling Visual Studio what executable to use in the project properties (under the Debugging category).
|
|
|
|
|
One important thing you need to be carefull to (and that you can easily forget) is that the executable should load the same dll version as the one which you are trying to debug. Typically, you will copy your dll in the executable folder or in the win32 directory. So, you have to make sure that each time you recompile the dll you also copy it for the executable.

Hi everyone,
Does anyone have an idea on how to move items within a CTreeCtrl by dragging them to a new location?
Thanks in advance
