I think I know what you are trying to do because I have to do the same thing.
The way I get around the problem is by using templates. Thus, you can declare variables in you H files without the compiler bitching.
template <int _Dummy>
class my_constants_
{
public:
static LPCSTR gm_pszFileName;
};
template <int _Dummy>
LPCSTR my_constants_ <_Dummy>::gm_pszFileName = "file.name";
typedef my_constants <0> my_constants;
To access the variable, you just say my_constants::gm_pszFileName.

I've used templates with similar problems, but it won't work with this scenerio.
Thanx anyways!

How about:
#define fileName "data.dat"
or something like that?

does anyone know how to use command line arguments with the Microsoft VC6.0?
thanks
|
|

Depending on which arguement that you are trying to use, you can set the command line parameter in the Project | settings menu option.
You can either select the different tabs in order to get a form to customize the command line, or you can directly edit the command line arguements in the edit box at the bottom of most of the tabs.

Nope! No one would know. Only devs at MS would. 
Just kittens.
However why would you wanna use dev studio cmdline...?
Are you trying to compile, link from the command prompt...?

Hi
I'm using CFileFind::GetLength() to get the size of a file. I'm storing the results to a double. The number returned is over 124000 bytes, the actual file size is about 10k. Am I doing something incorrectly? Any help would be appreciated.
Thanks

Call FindNextFile once before calling GetLength

I tried that and it still returns the length of the file as 1241156 instead of 151387. The code looks something like this:
CFileFind Finder;
Finder.FindFile(Filename);
Finder.FindNextFile();
double size=Finder.GetLength();

First verify that FindFile returns non-zero.
non-zero indicates success.
If FindFile() fails then FindNextFile will not work properly. Naturally GetLength() will also return abnormal values.
So chk and see if FindFile returns a non-zero value.

FindFile returns successful, but FindNextFile() will fail since I've given it the exact file to find.

I would like to implement some form of IPC, however I can't decide which approach to take..?
I am considering ReadProcessMemory etc...But wouldn't this be more work than nessecary...?
Could the same, but easier be accomplished with file mapping...?
It's to my understanding that ReadProcessmemory would only be required if the differeing applications didn't (at design) have the need to communicate. ReadProcessMem... could then be used to read memory into the desired process and acted on accordingly.
How much work would it be to implement File mapping for both sides, compared to ReadProcessMemory...?
Any suggestions...? ReadProcess could cause page faults huh...if used incorrectly..

Look at shared sections. This will allow 2 or more processes to access this IPC section.

I have a form view (inside Leo Moll's Property Sheet View) with controls in it. When I resize the window I get screen flicker in a major way.
Since I do not draw the controls, I can overwrite the OnDraw function. Where should I add my double buffering? Or is there another way?
Thank You

Have you tried using Keith Rule's CMemDC class?

I can't figure out where to but in this case.
|

Set the dialog control to clipchildren. Then when it paints, it will not erase the controls.
Also, if a control is flickering that doesn't have children and you will always repaint the control fully, then disable WM_ERASEBKGRD.

I am using Microsoft Vision SDK. I need to be able to open multiple bitmaps at onces, work on all of them and store the results as a txt file. Any ideas on how to cycle through all of the bitmaps opened and have a txt open/save dialog in addition to the bitmap one?
Your answer is greatly appreciated.

I've viewed the related articles on CP about CPU Useage and have only concluded that ntQueryPerfomanceCounter..?(i think) Is the only way to return CPU useage.
I don't suppose this works(or there exists a workaround) for WIN98...???
Thanx a bundle!

As far as I know, QueryPerfomanceCounter is the only way to obtain current CPU usage and according to the docs, it is compatable with W95 and W98. I believe there are few libraries around here that encapulate it. WFC is one.

Funny cuz I was just on CodeGuru and read a message thread with your name in it. I'll assume it was you, because the disscussion "CPU Usage".
Actually what i really wanted was CPU usage of each process.
I'm already using the RDTSC to perform code profiling and was curious if there was a way to return process usage (proportional to rest of system) as well. Turns out (so far anyway) that this would require a whole lot more work then i'm ready to put forth.
I'm assuming you'd have to count the clocks of each process at each task switch...?
In anycase, to much homework for me right now...
Thanx
