Hi all,

Given a string containing the shortcut name, how do I get the shortcut target path?

I tried to use BOOL SHGetShortcutTarget(...) but to no avail... My MSC++ couldn't find it, even after including Shellapi.h and linking to Shortcut.lib.

Any one has a clue on how to do this?

Thx!

AFAIK SHGetShortcutTarget is for WinCE only. I assume you're not using WinCE cos you'd probably have said so...

Frankly, i'd use the CShellLink class available on this site.

You'll also note that links like those which link to microsoft office are in fact special kinds of links which the API can't decode. and they're not documented. It's annoying.

Sorry to dissapoint you all with my lack of a witty or poignant signature.

Please Help!!!

Very important information about DLLs in VC++ !!!!!!!

Yes ,

It is again I ,
The nagger with the DLLs in VC++ for Delphi .
I at last succesed to find out what was the problem with my DLL by the generous help of Tom Nuydens, Smile | :)

Well,
When the VC++ linker generates its output it changes the names of the export functions If you gave to a function the name "foo" it will look something like "_foo@4" and This is the name you haveto import in your Delphi app client program. To see the export table, you have run :
"dumpbin.exe /exports mydll.dll" from the command line.
_________________________________________________________________-
Simple ? OMG | :OMG:

Not exactly !
I , for example , dont success to run "dumpbin.exe" im order to find out the export table of my DLL to see the names of the functions.

Is Someone know how to do it exactly ?

You can force your DLL to export the function names without any decoration just by declaring it to be extern "C" like this:

extern "C" {
/* your declarations here */
} /* extern "C" */

The name is the result of the _stdcall calling sequence. The @4 means that four bytes must be subtracted from the stack pointer by the calling code when the function returns.

Make sure that your functions look something like this :

__declspec(dllexport)
int __stdcall foo( int argument )
{
return 0;
}

This will insure that they are exported.

What problem are you having with dumpbin ? If it is not showing any exports then the problem is most likely with the dllexport statement.

A view inside a Tabcontrol

Hello Everybody,

I'm trying to insert a CView object
inside a TabControl.
I follow the following step:
a) Create a Dialog;
b) Inserted a TabCtrl
c) Created a CMyTabCtrl derived from CTabCtrl
d) Inserted a CView Object in CMytabCtrl.
e) Used CView->Create(...) to create a Child window inside the tab control

Is this the only way to create a view in the tabControl? Why the View position
is not perfectly inside the Tab Control Client Area?

BYE. Big Grin | :-D

Are you using MFC? Is this the main app's dialog box? Have you tried just changing the code to use DoModal instead of Create? If you show some code, I may help you better.

Assign Character Arrays data from an STL Container

Hi.

Let say there is a standard STL vector contain with data in it. How do you assign a character arrays the data inside the vector contain either through value or pointer?

I need to do that so I could write the data to a file in binary mode.

Thanks,
Kuphryn

I'm not sure I've understood your request, but if what you're after is getting a char * to the contents of a vector, then the expression &v[0] does the trick (v being the vector), as in

std::vector<char> v;
...
fwrite(&v[0],1,v.size(),fp);

Hope this helps.

Explorer-like interface

Hi,

I have an SDI 'windows explorer'-like application (generated by the AppWizard), with a left pane (CLeftView) and a right pane (CRightView).
Here are my questions :

- When the user opens a new file, a file selector is automatically openned. How can I choose the file type (*.xxx instead of *.*) ?

- I would like that when the user chooses to save the file, no matter which view is active, the same method is called. But, with the ClassWizard, the function to react to the 'OnCommand' for a menu is different for each view. How can I have a unique method for the 'File save', no matter which view is active ?

Thank you in advance for your help !

I assume you are using CFileDialog, look at its m_ofn member, this is of type 'OPENFILENAME' structure. The 'OPENFILENAME' has two members you need to modify lpstrFilter and lpstrCustomFilter.

How can I have a unique method for the 'File save', no matter which view is active ?

Create a static function somewhere to do the work, and then call it from everywhere else.

I use ATL COM Appwizard to create ActiveX,
I insert new "full controll" and in the "Stock Properties"
tab I add "Background color" and "Background Style".
when I test ActiveX in "ActiveX control text container"
there were not any propertypage for background color and
background style.
Should I add any code for it?

Re: ActiveX

Todd Smith4-Dec-01 20:16

When you select background color and style the appwizard includes a few more lines of code so that you can set the background color and style from the container.

Create a project with those options enabled and one without and then do a diff (windiff) between the two projects to see the difference.

How to get user set font point size?

Henry Jacobs4-Dec-01 16:50

Henry Jacobs

4-Dec-01 16:50

How can I find the user defined point size for message boxes (set under Display Properties, Appearance). I have checked GetSystemMetrics and SystemParametersInfo and have tried the following code:

HFONT   font = (HFONT)GetStockObject(SYSTEM_FONT);
LOGFONT lf;
GetObject(font, sizeof(LOGFONT), &lf);

HDC hdc    = GetDC(NULL);
int ptsize = MulDiv(72, lf.lfHeight, GetDeviceCaps(hdc, LOGPIXELSY));
ReleaseDC(NULL, hdc);

SYSTEM_FONT always results in 12 and DEFAULT_GUI_FONT is the menu font.

MFC DLL #2

I have created a MFC DLL, and everything works fine on the DLL side. But one the application side, the exported classes only work when they are declared in a function, and I have compiling errors when I declare them in a view or another class. What am I doing wrong?

The reason nobody answered your question the first time is because it is too vague to guess at. You need to be more detailed. What errors? What defines are you using? How is your project structured?

Simply reposting your question will achieve the same thing. Nobody answering it.
