I wanted to make some really large letters in my application but whenever I change the font size everything within the window becomes bigger, buttons, etc... Is there anyway to only change the letter font sizes only?
Thanks

If you change the font through Dialog Properties the dialog size will also be resized,
Instead change the font of a window from within the code
//put this in constructor
LOGFONT lf;
memset(&lf,0,sizeof(lf));
lf.lfHeight = -14;
lf.lfWeight = FW_BOLD;
lf.lfUnderline = (BYTE)TRUE;
_tcscpy(lf.lfFaceName,_T("Arial"));
m_fontBig.CreateFontIndirect(&lf);
Not set the font anywhere you like
m_targetWindow.SetFont(&m_fontBig);
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

Hi
for change font and font size you can use CreateFont and SelectFont

Hello, I'm trying to compile a sample DLL that I found while searching on the forums here.
Here's the link to it:
http://www.codeproject.com/system/winlogon_notification_package.asp[^]
I'm coming from a VB background, so some of this stuff is kind of new to me. I have worked with VC++ 6.0 many times, but I have never compiled a DLL. Can anyone please provide a walkthrough on how to go about compiling this DLL. It would be helpful if you could provide a walkthrough for this example specifically since I have the code and can follow it easily.
I've tried numerous things and I have not been able to compile sucessfully. I'm simply copying and pasting the code from the above link into an MFC AppWizard (DLL) and then trying to compile. One error I keep getting is:
error C2065: 'PWLX_NOTIFICATION_INFO' : undeclared identifier
As mentioned before, I am simply copying and pasting so I have made sure to copy the includes. So I have no idea why it would say that PWLX_NOTIFICATION_INFO is "undeclared". It seems like I have tried everything and I don't know how to go about compiling. Any help would be greatly appreciated!

I have already downloaded PSDK, I have version 5.2.3790.1830. Thanks for the quick reply! Any other ideas? Is there a specific project in VC++ that I need to create in order to compile the DLL? Or is there any way you can please set up the project files for me and attach them here so that I can take a look at them? Thanks again!

Check have you defined WINVER 500 or 501 as this defination is only available for WINVER 500 and above

Where should I check this? If this is supposed to be in my code, I am copying the code exactly from the forum. Or is this supposed to be one of my environmental variables? Thanks again Alok!

Well, I finally got the project to compile. I had to add the typedef struct for _WLX_NOTIFICATION_INFO and PFNMSGECALLBACK in order for it to compile without errors. But now my question is why doesn't it work? I have compiled the following code, and copied newNotif.exp and newNotif.dll to C:\Windows\System32\ and added the below registry entry to my registry. When I reboot, it doesn't do anything, not even the messagebox is displayed.

Hi guys~ I need to build a 3D map system that will accept 2 inputs from users (the current location and the destination user wants to go), by clicking, then the system will generate a path from the current location to the destination.
At first I planed to use OpenGL to do so....but I faced one problem. The exporter that I used can only extract the vertices of the model I built in 3DsMax, not included the texture mapping! I already done nice mapping in 3DsMax and I think it takes time to do mapping in OpenGL.(total up 15 buildings need to be mapped)
Therefore, I switch to VRML (because the 3DsMax can export the model to VRML file with texture mapped)but I found VRML is dead and not powerful at all. Then I switch to Java3D but I heard someone says this programming is dying and will run slow! The most powerful tools for 3D Graphics Application still belongs to--->OpenGL!! And now I stuck here~Time passed away quickly and I still not yet done my system!
I need some help from you guys and suggestions, advices from you all~Please...please help~~~~sob sob////
I more familiar with OpenGL if compared with Java3D and VRML(both I learned 3 days ago only,very unfamiliar~)
I wish to extract the model(with texture mapped) to OpenGl then I can quickly concerntrate on my system(my due date for this project is coming soon)
Thanks a lot!

Sir,
I amd Suresh Kumar want to know the differences between the VC++ and .Net. Please send me the differences I request. I referred many books but i didn't get any information regarding this and also searched on internet in many sites
including Microsoft.

f:\installation\vc98\include\xmemory(37) : warning C4100: '_P' : unreferenced formal parameter
f:\installation\vc98\include\xmemory(68) : see reference to function template instantiation 'void __cdecl std::_Destroy(unsigned int *)' being compiled
Error.cpp
I also got this error. It seems that it caused by the include header. How can i solve this?
Thanks again.

That is only a warning so you don't have to fix anything. The warning says that the function std::_Destroy(unsigned int *) did not use the one parameter.
