Hi everyone,
on my Dialog i have multiple components for example a label with a textbox a side
If i resize the CFormView ( Not the dialog -> MDI Project ) the event reacts each pixel.
How can i center the label with the textbox a side ?
My only idea is to get the position of the component and to move the LEFT (re-setting) one pixel farer.
Next event the RIGHT one pixel farer...
But aren't there more possibilities to center components?
many thanks

The only way to position something is to set it's position yourself, in code. Handle the WM_SIZE event.

S*** .. ok thanks
Before i started the hard way, i would ask about another possibility

Sure - there are better options in .NET, but not in MFC.

Hi, I am working on VC++ 2003. I am using a string as "char *pchData;". now at some point how can I check that 'pchData' is defined or undefined?
Thanks in advance

Your code is wrong. NEVER create a pointer without setting it to a valid value, or NULL. Then, just check if it is NULL.

If you're unsure whether a particular pointer is pointing at a valid address, then something's wrong with your design. In C/C++ it's the program's responsibility to make sure that pointers are either NULL or contain a valid address.
The IsBadXxxPointer() APIs are not reliable (search MS blogs for them, you'll find a few posts about how evil they are).

We have an application that was written on VC++ 6.0 a few years ago. Today a customer reported that it did not work on their 64 bit laptop (that's all they said 'it doesn't work'!). We are waiting for more info on the problem and we don't have a 64 bit system to try it on.
I just wondered, has anyone had any experience running 32 bit apps on 64 bit machines? Good / bad etc?
Many Thanks,
Ali

Thanks, I will take look at that - sounds like just what I need.

The first thing that comes to mind is that a 32-bit EXE can't load 64-bit DLLs and vice-versa. For example, a 32-bit IE plugin won't load in 64-bit IE. But without any details, we can only give you WAGs.

Fair comment, just checking out the general opinion. I thought a 32bit exe would run on a 64bit machine using WOW, and wondered if anyone else has had any trouble - looks like they haven't - its just my customer! 
Thanks Anyway,
Ali

It can, you just can't mix 32 and 64 bit modules in the same process.

rand() returns an integer in the range [0 - RAND_MAX]. What if I want to generate random integers in a wider range? is there no escape from calling rand() twice and then multiplying the results?
Is there a continuous random number generator in C++ ?
Thanks,
Avi.

That's not really random, nor does it give a wide enough range. Try calling it twice and shifting the first result to take the bits above the second result.

You could generate a random number between 0 and 1, then multiply that by the bigger number you want to use, e.g.
flaot fRand = rand() / (float)RAND_MAX;
int iValue = fRand * 10000000;
|
|
|
|

That won't work: some values might have no chances at all to be picked.

You'll need to roll your own. Something like this.

Make sure your ActiveX DLLs are registered. Are these functions graphical or non-graphical components? If they're graphical, you can easily use the dialog editor to put the controls into place, or you could use CWnd::CreateControl to create the controls.
If they're non-graphical components, there are basically two ways to use them. If your components expose interfaces with a vtable (IUnknown-based interface or dual interface), you can use the #import feature of Visual C++. The MSDN docs describe how they are used, and I'm sure you can dig something out about #import here on Codeproject. If not, Google is your friend.
If your component is dispatch only (no vtable), you don't need to #import the ActiveX DLL (unless you've defined structs or typedefs in the typelibrary). Then you can use the COleDispatchDriver class, which helps you to instantiate the component, as well as call methods and manipulate properties. This project could probably benefit you a lot: http://www.codeproject.com/com/xydispdriver.asp[^], as it simplifies the dispatch stuff a great deal.

Why don't you work out why it's returning false, and fix it ?

Thanks for your immediate reply...
its showing ERROR_FILE_NOT_FOUND when i try to fix it using the GetLastError() but i cannot able to find out the reason..
why it need to find the file on the ftp server it should just get store the specified local file on the server side....
Thanks
Shikha

Perhaps it can't find the local file ? Or you don't have permission to create the file, so it's not found when it tries to write to it ?
