I have the following snippet of code in two places in my MFC Appwizard-generated MDI (CFormView) application:
MSIHANDLE hMSIDatabase;
::MsiOpenDatabase( _T( "D:\\Projects\\MSIMaker\\UISample.msi" ), MSIDBOPEN_TRANSACT, &hMSIDatabase );
::MsiCloseHandle( hMSIDatabase );
The two places are in the CWinApp-derived class' Constructor, and the other is in an OnInitialUpdate of my CFormView-derived class. The first one, in the constructor, works great.
The second one, however, always fails with a return code of "110", and sets the GetLastError() value to "ERROR_INVALID_PARAMETER".
This only seems to occur after MFC is totally initialized and all of the Windows are created. Strange, but true. It continues to fail if I remove the first one.
The sample applications provided with the Installer SDK are all Console apps. Is that trying to tell me something?
Has anyone else out there experienced anything like this?
Peace!
-=- James.

My developer studio is extremly slow in the moment.
I am waiting about 1 minute when inserting a line into the code.
What can I do?
Thank you...

Try closing down DevStudio and then deleting your "Project.NCB" file.
Let me know if that works.

Did you try the Task Manager to determine "who" is using the processor? It could be another task entirely. Sometimes I have programming bugs that cause my program to get hung up without terminating but without a window. In situations like that, the program could be using up the processor. There are many other possibilities too.

Hello!
Can anyone tell me that how can I disable left/right click from Microsoft web browser control in an MFC dialog based application? Is there any easy method to catch WM_LBUTTONDOWN/WM_RBUTTONDOWN events on web control?
Regards

from the script you could do :
function inhibeClick()
{
window.event.returnValue = false;
}
document.onclick=inhibeClick;
document.oncontextenu=inhibeClick;
the "oncontextmenu" event is avaible only in IE5
from c++, your application that host the WebBrowser control must implement IDocHostUIHandler . for the context menu ( right click ) use the ShowContextMenu from the IDocHostUIHandler interface.
to inhibe the left click , connect to the HTML document events ( using AfxConnectionAdvise ) , and do the same thing like in the script function described : set the returnValue property of the event object to false.

Hi,
I am developing using VC6.0 SP3 on W2K RC3.
I want to print an euro symbol on a CDC object: eventually it will be a printer CDC object, for now it is a CClientDC object on a dialog.
I can input euro symbol on notpad and here(€, hold down right Alt and enter 0128 using numeric pad), but I cannot do that in VC. I know SP4 will fix this problem. But I would like to know whether there are other solutions. For now, I just use a bitmap to work around it.
Any helps and tips are appreciated.

Hello,
I'm making an application for reading out and setting up an external hardware unit.
Because it should work also on CE, I start of with a SDI application. The application should be made ready to work with all the different hardware units we already have and are planning to make. Therefore different views for the different units.
I checked the example COLLECT of MSDN to see how you can switch between Views.
Because one unit has a lot of different readings and settings, I have to make seperate "views" for them as well. My first idea was to use a tabbed view like propertysheet / pages.
I checked how propertysheets work in a dialog-based application.
My question and my problem is that I don't know how to incorparate the two things. Where and how do I declare the propertysheet and pages to show them in a view?
Probably somewhere in a OnCreate or OnInitialUpdate, but what if I choose to change the view during runtime?
Going the whole way with CTabCtrl doesn't seem to be that easy,because e.g. you have to handle a lot of messages yourself what is done for you with propetysheet and the easy use of resource editor when using the property sheet (that's what I understood after reading some documentation
about this in the newsgroups and on the guru-sites). I maybe wrong, but the Fire example in MSDN shows me all kind of things that are not necessary with property sheet.
Can somebody help me with some directions / info / documentation / tutorial / samples
By the way:
When I started to learn about MFC I think saw somewhere that propertysheets in WinCE are always MODAL. I can't find it anymore, so maybe somebody can tell me.
Thanks in advance,
Kimball

Hello all, maybe someone can help me with this:
I'm writing a program that displays a dialog box with a progress meter and a "cancel" button. The main thread creates the (modeless) dialog box, then starts the calculation. While it is doing this the dialog box is unresponsive, so I added a function that uses
while(PeekMessage(..))
to do message processing for the dialog. It is *more* responsive, but not as much as other progress dialogs I've seen in other programs. Is there a better way to do the message translating/dispatching so that it works quicker (ex: right now if you drag the window it takes 5 seconds for the window to actually move). I'm using straight API, no MFC.
Thanks to any who can help me

I have had a similar problem and I have seen this type of questions asked a couple of times at least in the CodeGuru forum. One thing that makes a difference is your requirements. Your description does not say much about the processing being done. So I will describe a few possibilities in some general terms.
The best solution is to use the MFC "worker thread" / "user-interface thread" solution. See the MFC documentation for that.
If you are not using any MFC GUI stuff or any other MFC stuff that needs the CWinThread class and such then you might be able to create a thread with the Windows SDK. You could use an event to signal the thread that the cancel button was pressed.
Another possibility is to modify your processing so that it can be done during idle processing. See CWinApp::OnIdle and:
http://msdn.microsoft.com/library/devprods/vs6/visualc/vccore/_core_idle_loop_processing.htm
That is the online copy of something you have on your hard drive.

Does anyone know how to use GetTextExtentExPoint and all similar functions to print WYSIWYG? I tried changing the mapping mode to MM_LOENGLISH, MM_ANISOTROPIC, MM_ISOTROPIC, but it did not work. For some reason font metrics are different Even though the mapping mode of the printer and monitor are the same.
PS. I wrote my own HTML print engine, it works great. The only problem is this. Let me know if you want the code.
Thanks, Italo S Weiss.

Actually i want to take data from the pci card. I have no idea how to generate interrupts and access PCI BIOS in VC. does anyone guide me for the VxDs.

Foremost, you need the DDK from Microsoft.
Another good invesment is to puchase the VToolsD commercial device driver development toolkit. It helps with the development of VXD and NT device drivers in C. A different toolkit from the same company is used to make the WDM type drivers.
They really are time savers.
Otherwise, you spend a LOT of time doing things on your own.
There is a book about writing VXD and device drivers in C, but I don't remember the exact title.

Hello Stupid,
If u don't know how to write VXD's then don't try to take PANGA with PCI port. Stupid ppl do like u. I advise u to leave the idea of taking PANGA with pci. Just work with Parallel or serial port. U deserve only for it.
O.K,
Bye Bye

Hi!
I want to select a folder in ::SHBrowseForFolder dialog. For this, I select a folder in the callback function of ::SHBrowseForFolder in this way:
static int __stdcall BrowseCtrlCallback(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData)
{
if (lpData) {
CFolderDlg* pFolderDlgObj = (CFolderDlg*)lpData;
if (uMsg == BFFM_INITIALIZED) {
if (!pFolderDlgObj->GetStartFolder().IsEmpty()) {
::SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)(LPCTSTR)(pFolderDlgObj->GetStartFolder()));
}
}
}
return 0;
}
ulFflags of BROWSEINFO I set to zero!
It works perfect for local and mapped folders. But when I try to select an UNC path like \\bo-pc\test\xyz, it dosn't work. If I select this folder in the browser dialog once, then it works. It works also, when I close the dialog and start the dialog again. Only after close the application, the selection dosn't work any more!
Who knows something about this problem ????

I want to change the Titletext of my MainFrame at startup.
Now I use SetWindowText(...) but this only takes effect when I click on my menu (I dont know why).
But I want the text written at startup.
Does anyone know what I am doing wrong?
Thank you...

Hope This will Help
void CFAdhlyView::OnDraw(CDC* pDC)
{
CFAdhlyDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
pDoc->SetTitle (_T("Set The title here"));
}

Override CFrameWnd::OnUpdateFrameTitle(). This is a virtual function, but undocumented, so you'll need to add the prototype yourself. When this function is called, call SetText() to set the frame window caption.
The default implementation is in winfrm.cpp, line 1746. You can check that out to get an idea of what you can do with the function.

MFC uses two parts for a window title composed of a "frame window title" followed by a "document name", but the frame window title is used only if the FWS_ADDTOTITLE Frame-Window Style is set.
See: http://support.microsoft.com/support/kb/articles/q129/0/95.asp for the Microsoft Knowledge Base article "INFO: Format of the Document Template String" that describes how to modify the windowTitle and docName strings; that might be relevant for you.
The document name can be changed using CDocument::SetTitle.

Hi,
i have a few questions about developing unicode application using different input locales.
I am using Windows NT English version
First what i have done:
- i added japanese as a new input locale
- i changed the compiler and linker settings to unicode
Questions:
How is it possible to enter japanese characters into an edit field? Switching the locale in the systray doesn't
have an affect to the input to the field. Do i have to install anything else? Do i have to install an IME? if so,
where can i get it. Does this only works with an NT Japanese version?
Where can i get same more information about IME and input of characters like japanese or arabic etc.
At least, enter japanese chars into an internet explorer entry field works after switching the locale. An
additional window pops up where i can select different input modes.
TIA, Chris
