He may be able to get the text as text (without OCR) for a specific control (in his case a flexigrid). I agree that a general solution that works for any control would need to use OCR however. Active Accessibility is also an interesting possibility for controls that support it.

I have written a C++ program and I wish it to be able to be started by dragging a file icon onto the program icon in windows explorer. The program name is prog.exe, the file name is file.syx, they are both in folder "H:\folder". When the file is dragged onto the program icon in explorer and starts, the value of _argc=1 with _argv[0] being "H:\folder\prog.exe" and _argv[1] being "H:\folder\file.syx" as expected. I then use this information to open file.syx.
However, if the program and file are moved to a folder with a space in the name such as "H:\copy of folder", then when I drag file.syx onto prog.exe I get these unexpected results. _argc=3 with _argv[0]="H:\folder\prog.exe", _argv[1]="of", _argv[2] = "folder\prog.exe H:\copyof~2\file.syx".
If I just double click "H:\copy of folder\prog.exe" I get _argc=3 with _argv[0]="H:\folder\prog.exe", _argv[1]="of", _argv[2] = "folder\prog.exe ".
I have tested this program on windows98 and windowsXP with the same basic results. If anybody knows how to consistently get the name of a file that is ‘dragged onto a program icon to start that program’ from inside that program then I would appreciate the help.

If this is a Windows application, why aren't you using the standard drag&drop interface instead of argc/argv?

this program also has drag&drop where a person could drag a file onto the open window of the program to open that file. I wish to be able to open the file as the program starts up. I beleve this would also let me set the file extenshion (.syx) to that double clicking a .syx file would open that file in this program.

If double-clicking a .syx file is not working, then you need to adjust its registry setting by surrounding the %1 parameter in double quotes.

I have went to folder options and set .syx to open H:\copy of folder\prog.exe Now when I double click a .syx file , it opens prog.exe but I do not know how to get the information about the opening file other than to us _argv, and it gives strange results. I beleive I am missing somethin since standard programs such as notepade and others do this with no apparent problem.

Do you have a console or a Windows application?
Look in the registry for your .syx extension and note what you see. How is %1 being handled?

I am curently using windows98. I have open regedit and did a search for .syx and did not find anything with %1 in it. I am afraid you may be going over my head. i.e. i'm lost.

Which matters not.

It should be near the top of the HKEY_CLASSES_ROOT hive with all of the other file extension types.
For example, if you look for .txt, you'll see it has a default value of txtfile. Looking further down the list for txtfile, you should find:
HKEY_CLASSES_ROOT\txtfile\shell\open\command
Does the same sort of thing not exist for your .syx extension?

under HKEY_CLASSES_ROOT/.syx It says (default) "syx_auto_file"
under HKEY_CLASSES_ROOT/syx_auto_file it says (default) SYX File
SYX File does not show up anywhere else

You should have a shell key under that. In all, it should look like:
HKEY_CLASSES_ROOT\syx_auto_file\shell\open\command
If not, why not make the necessary changes to see if that helps.

I must have missed the + befor the folder icon becouse there is HKEY_CLASSES_ROOT\syx_auto_file\shell\open\command and it's value is ""H:\Copy of folder\prog.exe"%1"
My apoligies for missing this the first time.

This is just a guess, but those double quotes look ill-placed. It's hard to tell which are actually part of the registry's value and which you added as part of the post. I would have thought it to look something like:
"H:\Copy of folder\prog.exe" "%1"

I got it to look like you said. now when I double click a .syx file I get _argc=4 with _argv[3] as H:\copyof~2\file.syx
I could use _argv[_argc-1] to get this value but I still get unexpected results from just double clicking the aplication icon in explorer window.
p.s. what does the %1 do?

Which it should be 2.
hlmechanic wrote: with _argv[3] as H:\copyof~2\file.syx
What is the value of _argv[0], _argv[1], and _argv[2]?
hlmechanic wrote: p.s. what does the %1 do?
Nothing per se. It gets replaced by the file that was double-clicked.

I am no longer at the same computer. now I am at a computer running windows XP. It gives me _argc=5. _argv[0] is still what is expected. The rest seem to be "H:\Copy of folder\prog.exe H:\Copy of folder\file.syx" with each _argv[] after 0 being a part of the line between spaces (except the space between the two file names). Windows seems to be trying to break the line up into arguments as a dos line would be. I was wishing there was a way to get this information that did not involve _argv[] or some way to make it give me the whole line so that I could break it up as I wanted.
Also I wanted to thank you for your help.

You still have not indicated whether this is a console or GUI application. That makes a ton of difference in how command-line arguments and drag/drop operations are handled.

I have found GetCommandLine() wich seems to be promising. When H:\copy of folder\file.syx is draged and droped onto H:\copy of folder\prog.exe then GetCommndLine() returns "H:\copy of folder\prog.exe" ":\copy of folder\file.syx" (including quote marks). If the same thing is done in H:\folder then "H:\copy of folder\prog.exe" H:\copy of folder\file.syx is given (note change in quote marks). I think I can get the filename from this.
I found this from the questions and answers at the end of the folowing article

If this is a GUI application, are you handling the WM_DROPFILES message?

This is a GUI. Written in Borland C++ 4.52
I handled WM_DROPFILES with the folowing code.
void DrumWindow::EvDropFiles(TDropInfo dropInfo){
int NumFiles;
char NextFile [MAX_PATH];
NumFiles = dropInfo.DragQueryFile (-1, NULL, 0 );// Get the # of files being dropped.;
for (int File = 0; File < NumFiles; File++ ){
if ( dropInfo.DragQueryFile (File,NextFile,MAX_PATH ) > 0 ){// Get the next filename from the HDROP info.
/////work with file name NextFile here if valid (removed to keep short)
};//end if next exist
};//end for each file
dropInfo.DragFinish ();// Free up memory.
};//end EvDropfiles
|

|

I'm confused. Why are you using GetCommandLine() when DragQueryFile() is how "dropped" files are retrieved?
