As I said I MUST code in certain style. So 'const' comes out of it.
|
|
|
|

You must add const in return type.
Like this:
const float GetVal()const {return val;}
Because the type of val had been upgraded into "const float" in the GetVal function.

hi all,
I am doing a Project using MFC.But I want to import a DLL.(name of the dll is "toks.dll").
How can I get details of Methods in that DLL file?.I want to get names of Methods,Return value of the Methods like that..
Can anybody please tell me how to get details of Methods in DLL?
thanks in advance.

|

open the dll using the depends.exe that comes with visual studio tools. dont know whether it gives the information on the method signature.
There is no spoon.

A DLL can expose the method names, (see the suggestion to use Depends.exe to find these out), BUT that's only part of the problem. There is no way for C functions to expose their return type or parameter list, so without this information you are hosed. Can't you get a header with the function signatures for this DLL?

Use GetWindowText() for this.

oki, does GetWindowText() only copying... or copying and pasting?
and if it is only for copying.. what i should use to paste?
thenks alot
|

GetWindowText() gets the text, SetWindowText(text) sets the text.
Where are you pasting the text to?

If you have the handle of the window you want to paste to, you could try sending it a WM_PASTE message.

MSDN is usually the first place I go to for such things. Google is another.

I am currently trying to develop a print provider. So, as the first step, I tried to compile and install the example which comes with DDK. So I successfully compiled "pp" and copied the relative DLL into system32/.
Then It comes the time to register into the spooler system the new provider, so I used the following piece of software, which calls AddPrintProvider ().
#include <windows.h>
#include <string.h>
#include <stdio.h>
int main (int argc, char* argv []) {
int result;
PROVIDOR_INFO_2 pi2;
pi2.pOrder = "C:\\WINDOWS\\system32\\pp.dl";
if (argc != 2) {
printf ("Command not recognized. Use ''install'' or ''uninstall''\n");
return 0;
}
if (strcmp (argv [1], "install") == 0) {
printf ("install... ");
result = AddPrintProvidor (NULL, 2, (LPBYTE) &pi2);
} else
if (strcmp (argv [1], "uninstall") == 0) {
printf ("uninstall... ");
result= DeletePrintProvidor (NULL, NULL, pi2.pOrder);
} else
printf ("Command not recognized. Use ''install'' or ''uninstall''\n");
if (result != 0)
printf ("ok\n");
else {
DWORD err = GetLastError ();
printf ("error: %d\n", err);
}
}
Well, I don't need to say that the output of the program is to signal an error. More precisely it signals error code #2 (file not found).
I tried various combinations of values for pi2.pOrder but I still can't understand what's going on and why it always gives me this error. The file pp.dll is into c:\windows\system32
The DDK documentation just says that I have to copy the needed files there and then call AddPrintProvider.
Does anyone know how to register a print provider ???
What am I doing wrong ??

Hello guys,
I am trying to play with a List control (report style) and I would like to do the following thing :
I select a row in my list (that becomes highlighted) and, thanks to 2 buttons (UP and Down), I exchange the place of this raw with the previous one (UP) to make it go to the top of the list or with the next one (DOWN) to make it go to the bottom of the list.
After a click on one of my buttons, I exchange the 2 rows, my row is no more highlighted and I would like it to keep highlighted. I have tried to play with the SetItemState to set the focus and the selection bits to make it highlighted again but without success.
So my question is : how do I give my row this selected aspect (highlight) by program?
Thanks in advance
DD

|
|
|
|
m_List.SetItemState(index,LVIS_SELECTED, LVIS_SELECTED);
this will do
|
|
|
|
|
hello,
that's exactly what I tried (except if my memory fails), LVIS_SELECTED as value and as mask ... I also tried LVIS_FOCUSED ... but without success.
I will doublecheck tonite.
This should immediatly highlight the item, no need of redraw or something else ?
Thanks for the answer
DD

Have you tried LVS_SHOWSELALWAYS Style? It always show the selection, even if the control does not have the focus.
Use SetExtendedStyle() to set the LVS_SHOWSELALWAYS.
P.
|
|
|
|
|
good idea !!
it is true that the list lost control because I clicked the button ...
Thanks for answer
DD

Strange .. it doesn't work.
In fact, if I add the LVS_SHOWSELALWAYS option, the control works as if there was a hot item, the fact to keep the mouse pointer over an item selects it, but as soon as I click my buttons, the highlight desappears ...
Very strange ...
Could it be a kind of icompatibility with another option?
I also use : LVS_EX_CHECKBOXES, LVS_EX_FULLROWSELECT, LVS_EX_GRIDLINES, LVS_EX_INFOTIP, LVS_REPORT
I really don't understand what happens ..
Thanks in advance for help
