Hi,
I need to pass a relativly complicated struct into a dll calling a CORBA Service which has to be written in vc6.0 and it has to contain many elements which are necessary to create an input for a service.
Unfortunately I can see only the first array element, other are ignored.
Here an example of c# code:
<br />
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]<br />
public struct MyStrStruct3<br />
{<br />
public string FirstName;<br />
public string FamilyName;<br />
public int size;<br />
}<br />
<br />
[DllImport(@"C:\Projects\CorbaLib60\Debug\CorbaLib.dll")]<br />
private static extern int TestMe(ref MyStrStruct3[] pstr);<br />
<br />
MyStrStruct3[] Names = new MyStrStruct3[2];<br />
Names[0].FamilyName = "Konieczny";<br />
Names[0].FirstName = "Marek";<br />
Names[0].size = 3;<br />
Names[1].FamilyName = "OtherName";<br />
Names[1].FirstName = "OtherFirst";<br />
Names[1].size = 2;<br />
int miki1 = TestMe(ref Names);<br />
C++ code look like this:
<br />
typedef struct _MyStruct2<br />
{<br />
char* FirstName;<br />
char* FamilyName;<br />
UINT size; <br />
} MyStruct2;<br />
<br />
<br />
int TestMe(MyStruct2* pStruct[])<br />
{ <br />
int Size = 2;<br />
<br />
for (int i=0; i<Size; i++ )<br />
{<br />
int woofie = pStruct[i]->size;<br />
char* miki = pStruct[i]->FamilyName;<br />
char* miki1 = pStruct[i]->FirstName;<br />
}<br />
return 42;<br />
}<br />
I define export :
<br />
<br />
__declspec(dllexport) int TestMe(MyStruct2* pStruct[2]);<br />
<br />
It works, but only for first element.

I am surprised it worked at all!
The structure has pointers to memory and unless you are sticking the memory for the strings onto the end of the memory for the structure, I am not seeing how the memory for the strings are getting into the DLL.
This seems like more of a C# problem than a problem with the DLL you are calling - might be better to post this to the C#-related message board.
Peace!

You should look up the MarshalAs attribute, especially with the UnmanagedType.LPTStr and UnmanagedType.LPArray parameters.
And I have to agree that this question would fit better into the C# forum.

Whenever I run some fullscreen games (not all, curiously), the Network Status and Task Manager's CPU usage icons (sitting in the systray) redraw themselves on top of the game's display every couple of seconds, creating some annoying flicker. I've noticed that this problem happens with *some* video drivers...one version will have that problem, another version won't...I usually try to keep up to date with my drivers, and the problem comes and goes. You'd think if the problem got fixed in version X, then it would remain fixed in version X+1. It seems like a crapshoot.
My solution is to uncheck the "Keep the taskbar on top of other windows" option before launching a game (and then re-check it when I exit), but having to do this every time is annoying, to say the least.
I thought I could write some little utility to toggle that option, so I could write a batch file to call it, run the game, and afterwards call the utility again to reset the setting.
My question is, how do I programmatically change that setting?
I suppose changing the taskbar's "autohide" setting would also work, so if anyone knows how to do either...?

Interesting.
However, that's not quite what I'm after. I want to programmatically change the "Keep the taskbar on top of other windows" option, not merely display the dialog box that presents this option. I mean, ultimately, when you check/clear that checkbox, some API eventually gets called or some registry setting gets changed. This API/registry entry is what I'm after, so I can change the setting without showing some UI or involving the user.
As far as I can see, this just programmatically displays various dialog boxes.

Just wait a moment I can bang in something for you. I remember doing this.

Hurray Dan, Gotcha,
Msg 0x02b1 WPARAM 0x7 Taskbar always on top
Msg 0x02b1 WPARAM 0x8 Taskbar normal.
For Eg:
<br />
::SendMessage(hShellWnd, 0x2b1, 7, 0);<br />
::SendMessage(hShellWnd, 0x581, 1, 0);<br />
::SendMessage(hShellWnd, 0x550, 0, 10001);<br />
<br />
<br />
::SendMessage(hShellWnd, 0x2b1, 8, 0);<br />
::SendMessage(hShellWnd, 0x581, 1, 0);<br />
::SendMessage(hShellWnd, 0x550, 0, 10001);<br />
::SendMessage(hShellWnd, 0x579, 0, 0);
You will have to check this code. It worked for me sometime back. Hence not sure.
I got this from spy++ sometime back.

Set it back to it's original state once the application exits. Users hate to see their setting changed. 
|
|
|
|

Of course. That was part of my original requirement; I certainly don't want to make the change permanent, or else I would just do it once and forget about the whole idea of writing a program... Re-read my original post.

1: Search the articles here for Shell_NotifyIcon.
2: Look up the WM_DEVICECHANGE message and any KB articles associated with it.

Hi,
I created a simple DLL which is executed from IIS through a webpage. Could anyone one tell me why I can't create a window in this DLL. I'd like to create a window, render something on it then grab the image and send it back to the client through IIS. The moment I issue a CreateWindow call and run the dll from a browser it hangs.
Sam.

I have linked dynamic linked library myfunctions.lib file in my project by setting its path in Project/Settings/Link/Input. And I have to place myfunctions.dll either in the same folder of my project's exe or in the system directory.
Can any one suggest me what should do ? if I want to place that myfunctios.dll in some other folder??

Add the folder path into the Additional Include Directories in the project settings.

Either one will work normally. I would suggest in the EXE's local directory, just to make sure you do not mess up any other application that might be using the same DLL (if not an internal DLL) - if you having questions about something like this, dicking around with the Windows/System directory is a bad idea.

but my requirement is such that I need to make one folder in my project's exe's path, and I need to place myfunctions.dll in that folder. Doing so, it gives error tha "dll not found" and terminates the application.

|
|

I tried out this, but it works in case we want to include lib or header files. In case of dll it does not work. Still it gives me the error that "dll ot found. ReInstalling the application may fix this problem."
