Hmm ok, that makes sense, but I'm having problems because I'm using inno setup which doesn't appear to have direct support for this - I can only really get at the command line, unless I start making mini installers to do the job. Is there any way of doing it simply through the command line?

No. What you can do is write a test EXE that does nothing but call SetupCopyOemInf with, say, the INF you specify on the command line. (Added bonus, you can manually copy files, then call your EXE directly to make sure it is working independent of anything else before you put it into the whole setup.)
There may be ways of hacking the registry to do this, too, but I would strongly recommend against doing that.
Unfortunately, installation of drivers is something very poorly supported by setup applications, so writing little custom utilities like this is pretty much all you can do.

I'm trying to use the COM viewer to get ProgID's for controls and use them, but I'm doing something wrong. The CreateDispatch works fine for a control (in this case, the Thumbnail viewer), and I can even call the methods, but I don't know how to draw an instance of the control on my form. Can anyone help?? Thanks in advance.
If it's broken, I probably did it

Hi, I've got this problem when developing my first DLL:
I have a DLL with an Interface class. I also have an application that calls some functions from the Interface class.
In the application there exist a function that I want to be called from the DLL (as a callback), so I pass a function pointer to the DLL.
I want to store the function pointer inside the DLL so I can call the function whenever I want, for this reason I have created an struct in which I store the function pointer and some other things. Until here, everything fine...
The problem comes when doing an instance of the struct; if I do that instance inside the Interface class (as a member) I cannot copy the function pointer in it; but if I do the instance outside any class (that is as "global") then there is no problem when copying the functon pointer.
Does anybody knows why can this happen?, it can be a problem of memory access?
Here is a "meta-language" example:
DLL:
In Interface.h:
typedef struct
{
functionpointer
}MyStruct;
class Interface
{
Interface ();
MyStruct mystruct;
void FillStruct (function_pointer_from_outside); //this is the exported function
}
In Interface.cpp
void Interface::FillStruct(function_pointer_from_outside)
{
mystruct.functionpointer = function_pointer_from_outside; //THIS GIVES EXECUTION PROBLEM
}
On the other hand if I make something like this, it works:
In Interface.h:
typedef struct
{
functionpointer
}MyStruct;
class Interface
{
Interface ();
void FillStruct (function_pointer_from_outside);
}
In Interface.cpp
MyStruct mystruct; //Instance as "global"!!!!!
void Interface::FillStruct(function_pointer_from_outside)
{
mystruct.functionpointer = function_pointer_from_outside; //OK!!!
}
HELP!!

what exactly is the problem? compile error? run-time error?

Run-Time error. There appear a windows called "Just-In-Time Debugging" saying:

Hi.
I have developed an application, (dialog based), that has a starting dialog, (app. main window), that prompts for a password. When I minimize this dialog I can see the typical icon for a window in the taskbar, but the following forms that are called later, (the password form calls to another modal dialog and so on), when I minimize them, instead of being located in the taskbar they are all over her.
How could I fix this?. I would like that any form can be seen in the taskbar when I minimized it.
Thank you.
Demian.

Does anyone know where to start with enumerating available devices? I've got the code to write out to a device, but i'm looking for a way to query for that devices name.
MSDN is decidely unhelpful, most of the code refers to XP SP1, which is a platform that we can't use.
I know it has to be possible because the OS displays the name of the device as it connects.

Hi there,
I need to know whether the mouse cursor is within a certain area and if it has one (or more) buttons down -- but I have to do this without passing through an event handler.
Is there a quick, easy way of knowing the current mouse state? Something similar to GetKeyState() but applicable for the mouse?
Thanks a lot,
David

GetAsyncKeyState is the function you want for mouse buttons, pass in VK_LBUTTON / VK_RBUTTON as appropriate

Hi,
I have a dialog box which have a Tree Control on it. Style of this control is as "Check Box" i.e all the root items as well as child items will be checked by clicking on these check boxes which are against them.
Now here is the my requirement:
I want that when I check the parent item then all its child items should get checked automatically. Similarly when all the child items get unchecked then parent item should get unchecked automatically.
Please suggest how i should do this.
Regards,
Amit

I need to open a .dmp file from the menu in a SDI a application. When I click the dump(instead of open file) command in the menu, the file open dialog box is opening but the file is not getting displayed in the SDI client area neither it is opened in notepad. Can anyone tell me how to open in notepad or in the document view itself.
Thanx & Regards,
Srini.

Does the file contain any non-white characters? If not, you obviously are not going to see anything.

Hi,
It is not an .dmp file but a .dat binary file. Sorry for the mistake. First I want to display the file and then I need to read it to do some manipualtion with the bits. How can I read the binary data bit by bit?
Thanx & Regards,
Srinivasan.

I'm not sure, but if you want to read it one byte at a time, try:
CFile file("myfile.dat", CFile::modeRead);
BYTE buffer;
while (file.Read(&buffer, sizeof(buffer)) > 0)
; However, you should note that this approach is very inefficient for medium to large files. A better approach would be:
CFile file("myfile.dat", CFile::modeRead);
BYTE buffer[1024];
UINT uBytesRead;
while ((uBytesRead = file.Read(buffer, sizeof(buffer))) > 0)
{
for (UINT uIndex = 0; uIndex < uBytesRead; uIndex++)
;
} This should give you the idea that less disk I/O results in increased performance.

hi all,
I have an application which communicates with a device..and when i click on UI and start multiple UI's, fill all the details, and OK, them one after the other,
job of each UI are queued and executed one after the other..I face some kind of timing issue when I use the release version of the exe or even the debug version of .exe.
But when I just attach this process to the VisualC++ debugger , by Build -> Start Debug ->Attach to process, and i don't put any breakpoints in anywhere in the code,
then it works fine..
What i would like to know is, how the attaching this process to debugger effects any .exe..pls note, I am not putting any breakpoints...so there's no way of adding human delay..
Any ideas...

hi everybody,
I am using Visual C++.Net & going to create a MFC Project with HTML Support.There are 3 Dialogs in my Project & they inherits like this:
class firstdialog : public CDHtmlDialog
class seconddialog:public CDHtmlDialog
class thirddialog:public CDHtmlDialog
Now I want to appear these 3 dialogs using in a same window using CPropertyPage class (Like excel sheet).
I am going to do like this:-
CPropertyPage c1;
c1.addPage(&firstdialog);------But this is wrong because firstdialog Must be a inherits from CPropertyPage
How do I do that?.
anyone know these things please tell me .
If there easy way to show these 3 Dialogs in a same Window with conecting Tabs(Like excel sheet)

The most viable option is to use a CTabCtrl in combination of a few CDHTMLDialog objects. This is called "Creating a custom MFC class"
First, design the dialog templates, or the HTML pages to show in them. Give each of them the 'Visible: FALSE' property, so they won't be displayed automatically. An alternative is to omit the WS_VISIBLE flag in the creation call.
Then derive a new class from CTabCtrl and add an array of these HTML dialogs (CDHTMLDialog ) as a member. During construction phase, each dialog is created. When the tab control is displayed somewhere, the tab selection determines which of the HTML dialogs is visible. When the tab changes, the old dialog is hidden and a new dialog is shown.
Needless to say, for this to work, each dialog must be exactly the same size and reside in the same position. The most efficient way is to save this information from the dialog that is being hidden, then reposition/resize the dialog to be shown before displaying it.
The road you're about to venture is not an easy one. But it is doable, and shouldn't take extremely long to design/implement. But it won't probably happen overnight, unless you're a true expert of MFC
