old, but i like vc++ 6.0 since i can transport it on my usb.
I had the same problem and this worked for me. Download visual studio SP6 found here.

If you have trouble installing it, and it gives you some error about running a 16 bit program, it is because your system is not creating short file names. You can just extract to the C:\ drive to a folder with a really short, no space name, or for a more permanent fix, look here
http://www.cloanto.com/kb/14-131[^]
which pretty much says
If the following value is set to 1 then short file names are not created:
* HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Control\FileSystem\
NtfsDisable8dot3NameCreation=1
If the value is missing, or set to 0, then short file names are created:
* HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Control\FileSystem\
NtfsDisable8dot3NameCreation=0
Also, i had set it to compatibility mode at first which didnt work, and after I updated, this was causing it to still crash. So turn off compatibility mode.

In a tree control with expanded nodes, Leaf and "Has Lines" structure, I would like to put a bigger icon/bitmap there, but seems like no space there for more than a very small simple icon after the dots...Am I missing something to be able to create more space for a bigger icon, or is it just the way it is?
Thanks

For CTreeViewCtrlEx, TVM_SETITEMHEIGHT, see <a href="http://msdn.microsoft.com/en-us/library/bb760104(VS.85).aspx">http://msdn.microsoft.com/en-us/library/bb760104(VS.85).aspx</a> 'sets the height of the tree view items'. Possibly this leaves more space?

Hi,
I have a double value describing rotation angle for a text box object. I need to convert it to quaternion. I have searched the web, and all I get is converters that conver Euler angle to Quaternion.
I would appreciate any formulae or algorithm.
And this double value is the only information I have for rotation.
Regards,
Shoaib

As far as I know, a quaternion is used in 3D. So how can you convert a double which represents an angle into a 3D rotation ? You need to at least have a rotation around an axis...

Yes you are right, its to be used in 3D. I am not good in this domain. The docs for that double value say "angle in radians rotated from +ve world x-axis". Does this indicate something ?
update: Now I understand that I need a vector, along with the angle for the conversion, but that vector is no where to seen in the information object for the text box. Is ther anything I can use as default for +ve world x-axis as it says above.
Its never over !

If your object is actually existing in 3D space then you should have everything you need. You can create your quaternion as follows:
Quaternion Q;
Q.x = x * sin(Angle/2);
Q.y = y * sin(Angle/2);
Q.z = z * sin(Angle/2);
Q.w = cos(Angle/2);

I am reminded of when I told a programmer that OpenGL didn't understand "2D". when you deal with 2D references all you are doing is nulling/zeroing the other rotations. If Z is into the screen (a common reference) then heading is your rotation of a window plane clockwise. All other references would be zero. So you can easily use 3D references to modify 2D parameters. If you write your own window compositing display a flip forward would be pitch and flip left/right is roll. you cand do some pretty cool displays.
the hardest part is Euler to quaternion is reference specific. Is +Y out of the screen? is +Z into our out of the screen? so you have to watch your references.
in reality you don't need to choose. If you are using only one view, one rotation, you can fake it by choosing an angle and always using that one for window rotation. You might get into trouble when you try to share, but you will find quaternions pretty lie/mistake proof as long as you are carefully consistant.
I prefer thinkin in top down 3D where window rotation clockwise is Euler heading.

Just part of the 32 bit color depth picture is displayed when my program runs in XP while in win server it is fine.
I made a new MFC application with .net 2005 and all i have done was that i put a picture control on the form and the picture that it displays is a 32 bit color depth
Any solutions????
Thanks in advance

I don't see a question, only some vague statements. This seems to be the norm on codeproject lately. I would recommend that you clarify your statements and form a proper question. How to get an answer to your question.[^]
Are you referring to the CStatic based picture control available in the VC toolbox? How are you loading/painting the 'picture'? What bitmap format is the picture. Are you loading it from disk or from resource? What API are you using to read bitmap?
Best Wishes,

Can you more explain for your problem you have a control(for example static control) and you loaded a picture on it then...?

My problem: I made
1- A new MFC application (exe) (c++ .net 2005), dialog based.
2- Get from the toolbox a control which is "Picture".
3- Set the type of the control to Bitmap in the property window of the control.
4- Add new bitmap to the resources at which this bitmap is 32 bit color depth picture.
5- Set the Image property of the "Picture" control to the previous Bitmap ID in the
property window of the control.
6- Build and run the application on WinXP and make sure that the appliction is enabling XP theme.
Note to enable it if it is not enabled write this line in "Additional Manifest Dependencies"
in linker node, in Manifest file Node:
type='Win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='X86' publicKeyToken='6595b64144ccf1df' language='*'
When I do all this steps just part of the picture is displayed while if take the application and run it in Win server the picture is displayed perfert.
I hope that explains my problem.

I think you made a toolbar and also you have a standard toolbar on your program but what do you need exactly?

You may want to start with figuring out how the service is

Hello,
I need to use a DLL which was written in Delphi in my VC++ windows forms application. However, Delphi doesn't generate a .LIB file when creating DLL's so I have to create a .LIB file manually. I have already written a .h file for the functions that I need to use. The .h code is shown below.
<br />
1
2 extern "C" { <br />
3 <br />
4 __declspec(dllexport) void* __stdcall CITRemote_create( <br />
5 void *parameters ); <br />
6 <br />
7 __declspec(dllexport) int __stdcall CITRemote_open( <br />
8 void* handle, void* parameters); <br />
9 <br />
10 __declspec(dllexport) int __stdcall CITRemote_close( <br />
11 void *handle ); <br />
12 } <br />
From what I understand I need to create a .DEF file to generate a .LIB file with the LIB command: lib /def:CITRemote.def. The .DEF file I wrote is shown below.
<br />
1 ;File: CITRemote.DEF <br />
2 LIBRARY "CITREMOTE" <br />
3 <br />
4 EXPORTS <br />
5 CITRemote_open <br />
6 CITRemote_close <br />
7 CITRemote_create <br />
The name of the DLL is CITRemote.dll and uses the STD calling convention. After I execute the LIB command, CITRemote.lib and object CITRemote.exp are created. I added the lib and exp file into my project in the 'Resource Files' filter. When i try to call for example the CITRemote_create function, I get the following error:
<br />
Linking... <br />
1>LINK : warning LNK4075: ignoring '/INCREMENTAL' due to '/LTCG' specification <br />
1>NTP checker.obj : error LNK2001: unresolved external symbol "extern "C" void * __stdcall CITRemote_create(void *)" (?CITRemote_create@@$$J14YGPAXPAX@Z) <br />
1>C:\Documents and Settings\Aartun\My Documents\Visual Studio 2008\Projects\NTP checker\Debug\NTP checker.exe : fatal error LNK1120: 1 unresolved externals <br />
So i guess the implementation of the function isn't found, thus meaning it doesn't link the DLL. But what am I doing wrong, did I miss something?
Thanks in advance.
Note: I'm using Visual Studio 2008 Proffesional and all the files(dll, lib, h, exp and def) are in the same directory.

You want to change the CITRemote.h file to say __declspec(dllimport) rather than __declspec(dllexport).
You are specifying that you want to export those function from your Windows forms app. Then, when you link, it can't find an implementation for them - because the implementation is in the Delphi DLL....
As an aside - if you were using the linker packaged with GCC, you wouldn't need a .LIB file - it can link directly to DLLs. I've often wondered why Microsoft's linker didn't have that capability.

i need accuracy as well as i have to interact several time with user interface .if i use multimedia timer for accuracy then it slows my interface response.how could i achieve both accuracy as well as quick response from interface??
i read about queue timer form msdn that it is accurate as well as do not stop window messaging .but when i used this,this is n't accurate..
