Use .SetFont() on the control. It is going to want a CFont, you can call CFont's CreatePointFont(), or if your feeling picky call CreateFont() with 14 arguments of font flexibility.

Trying to load bitmap from a path in GDI+

Anonymous8-Jun-05 8:05

I'm trying to load up a GDI+ bitmap using a pathname, and it does not work.

Here is what I try to do:
Bitmap bitmap(L"Images\\picture.bmp");

What DOES work is:
Bitmap bitmap(L"picture.bmp");
i.e., if the bitmap is in the same directory as the program

Bitmap bitmap(L"C:\\Images\\picture.bmp");
i.e., providing the full path name from the C drive

However, I cannot load it up from the base directory of the program for some reason. The picture is, of course, in the folder, and it works if I specify the entire path name starting from C drive, but not if I attempt to start from the program's directory.

Help ??

Thanks

Just a guess, but try L".\\Images\\picture.bmp".

Since you know that the image is in the Images folder that is in the folder of the app, you could use the GetModuleFileName to get the app's folder and then append the Images\\[imagename] to it.

Indeed, this is what I ended up doing. I guess it ends up being the same thing in the end.

Hi,

I use EnumResourceTypes & EnumResourceNames to get all the Resources of my multilanguage DLLs system, trying to translate the DLLs strings.

But I can’t get the strings of the dialogs (statics, group boxs, ...), menus, ..., and I don’t know how can I do it. May you help me?

Thanks in advance.

Get Value From Registry Key

Alright lets say I want to get the value from a particular registry key. How would I go about programming that to actually accomplish this feat.

Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Test
Name: home
value: testvalue

Would this correctly output the value located in said key, with the name of "home" into the variable value that I've defined.

char* value = NULL;
LONG l = 0L;
HKEY hKey = {0};
l = RegOpenKeyEx (
HKEY_CURRENT_USER,
_T("Software\\Microsoft\\Windows\\Test"),
0,
KEY_NOTIFY,
&hKey );

if(l == ERROR_SUCCESS)
{
// The following call will wait until a change is made to the registry key.
l = RegQueryValueEx(
hKey,
TEXT("home"),
NULL,
NULL,
value);
RegCloseKey(hKey);

Use CRegKey defined in atlbase.h

here is the small piece of code to accomplish that Smile | :)

 CRegKey l_regKey;
  
  // Open registry location
if( l_regKey.Open(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\Test")!=ERROR_SUCCESS))
 return;

 // now as you mentioned you want to retrieve String value
 DWORD dwCount=0;

 // Make a False call to retrieve the data length
  l_regKey.QueryValue(NULL,_T("home"),&dwCount);

 // now allocate string size
 LPTSTR pszRetStr=new TCHAR[dwCount+1];

  // Now retrieve the value from registry
 if(l_regKey.QueryValue(pszRetStr,_T("home"),&dwCount)==ERROR_SUCCESS)
 {
  MessageBox(pszRetStr,_T("Registry Value"));
 }
   
    // delete memory allocated to pszRetStr;
   if(pszRetStr)
   {
    delete [] pszRetStr;
    pszRetStr=NULL;
   }

I was trying to now look up the registry key value of ProxyEnable:

This is located in "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings", I was trying to edit your code to work with the fact that this is a DWORD. But I can't seem to get it to work, what I want to do is query the value of that key. After I have the value I just want to write a simple if-statement that will execute ProxyOn() method if the Proxy is seen as being enabled and a ProxyOff() method if the proxy is disabled. Any assistance would be greatly appreciated.

making a library

im trying to make myself a new library using visual studio and everything i try doesnt seem to work. i think that i got a library, but im not sure if its the right type or if i made it right. and if i did it right i have no idea which header to use or how to call my functions from each library.

i understand that this is probably a hard subject to explain over a computer but any help would be greatly appreciated.

thanks

How to make a library can be ambigious. There are many types. You could have .dlls, or .libs that are directly linked into the program or just a directory of headers or even headers with source. I'd consider those all libraries. So how to make each one.

To make a library which is used at runtime, use .dll. Make a new win32 application that is a dll project and then in the project you want to use the .dll, include the header to the .dll. Source is not needed, but the header will always be needed for whatever library you make. Unless you do COM or things of that nature.

To make a library where no .dll is required because you wanted it linked in statically use a .lib. Create a .lib project for your library and then in the client project add the .lib to the linker tab in project settings and include the header.

For the other two just make sure the client application includes and has access to the files needed. This is the simplest of libraries.

EMF Coordinates & Dimensions

I have a problem with images which I export from a Power Point presentation into an emf file.

When I go record by record through the file, the coordinates I receive are huge (1000's). However inside the presentation the item may only be 100x20.

Does anyone know of a way to convert the huge coordinates into the one's that are usable in the normal coordinate space?

Thank you.

EMF coordinates are stored in HIMETRIC (.01 millimeter) units.
See HIMETRICtoLP() for conversion to logical device units.

Thank You Shog,

the function you mentioned does seem to make the coordinates more realistic. However I am still having a problem getting the accurate coordinates. The problem I am having is when I pass a RECT to the EnumEnhMetaFile function (which according to MSDN should bind all the drawing calls to within that rectangular region), the coordinates are still outside of the rect. I may pass in (0,0,100,100) but i will get coordinates that are somewhere in the seven hundreds. And to top that off, I have noticed that regardless of the RECT I pass in, the coordinates the function returns always stay the same (as long as the image is the same).

Any suggestions as to what I may be doing wrong?

Thank You,

Ilya

cross references tools?

hiho@ll

anybody knows a good tool which can analyze my code (or just an C/C++ (would be cool with some MFC or "windows" features)) and show me the cross references of my code:
which function is called by which code

i know xref for linux, but is there a similar prog for windows (maybe graphical)

what i finally want is to learn "foreign"-code faster, because sometimes i have to read code from someone other and it's a little bit hard to read it without a good overview

thx@ll

Visual Studio has one already built into the IDE. Just select Source Browser (Alt+F12) from the Tools menu.
