The referenced article uses StretchBlt() to scale the image.

If you want to zoom a bitmap, that is the same as stretching it. So use the StretchBlt() function. By specifying the destination coordinates to be larger than the source coordinates you will get the effect of zooming in. By making the destination coordinates smaller than the source coordinates you get the effect of zooming out.

Look up StretchBlt() (or CDC::StretchBlt()) in MSDN for more information.

database problem

hi all!!

i have a small problem. i have designed an application which uses MS-ACCESS to log data. now, my application can be started only by administrator. when i log in as any other user other than the administrator my application will not start. but if i had started it as administrator and then logged in as any other user, it should run. The application no doubtedly runs but the the logging does not happen. i think this happens because, the databse gets closed when i log off as administrator. is there any way that i log off but the database does not close. or any other solution that u ppl can suggest me.

are you sure, your app is running after logout??
is it a normal windows app? I'm sure, all user-apps are killed on logof.

my application is interfaced to a driver that i have written. the application is destroyed no doubt. but the driver is not until shut down. so when i log in i re-create the user-land windows application. will event log work in my case instead of database?

I wrote a service, and this service has some connections to a access-databse and a ms-sql server database... and it works quite well.
so... theoreticly.. your approach should work Blush | :O

Open/Save Dialog

Ok, in most of the Open/Save dialogs i see professional programs using it has 5 buttons on the left side (History, Desktop, My Documents, My Computer, and My Networking places)

i am already familiar with how to use the CFileDialog class, but i cant get those buttons to show up, so is just becuase i havn't found the right parameter to add, or does MFC just not offer a template class for that?

I believe all you have to do is #define _WIN32_WINNT 0x0500 in your stdafx.h file. Just be aware that your app will not work on Win9x or NT4 if you do.

This won't work because the MFC libraries and DLLs have the old size of the OPENFILENAME structure (76 bytes vs. 88 bytes) compiled in.

You cannot use CFileDialog for this. You must use GetOpenFileName()to get the "Places" bar. Just remember to omit the OFN_ENABLEHOOK flag. Its presence will cause the "Places" bar to not show up.

Does anyone know how to redirect the dial button message in Outlook, so that it will call a custom dialer other than the 'standard' dialer.

Happy programming!!

Seems you want to introduce a functionality of your own to an existing event handler of a button right ? If i am right you have to write COM based plug ins for Outlook . I did it long back . But a perfect example is available here at CP itself if i remember well. you may search in PlugIn section ..

Want an Example of EnumPrinter Function

Hi
I want to write a console based simple application. Which on executing gives the name of all printers that are currently connected to network.

The function to do that is EnumPrinter and it's prototype is as :

BOOL EnumPrinters(
DWORD Flags, // printer object types
LPTSTR Name, // name of printer object
DWORD Level, // information level
LPBYTE pPrinterEnum, // printer information buffer
DWORD cbBuf, // size of printer information buffer
LPDWORD pcbNeeded, // bytes received or required
LPDWORD pcReturned // number of printers enumerated
);

Can any one plz give me exact example of how to do this ?

Thank you

I dont think an Example is needed here. Just go through MSDN and see what all these parameters are doing. You will get to see the sample values of these parameters as well. However, if you are getting error in a specific argument, then tell us.

And if you are confused how to call an API from VC, its simple Smile | :)

. Just call it as a normal function.

Think Negatively, It makes you creative Confused | :confused:

EnumPrinters(PRINTER_ENUM_NETWORK, NULL, 1, (LPBYTE) lpPrinterInfo1, dwSize, &dwSize, &dwCount);
 
lpPrinterInfo1 = new PRINTER_INFO_1[dwSize];
 
EnumPrinters(PRINTER_ENUM_NETWORK, NULL, 1, (LPBYTE) lpPrinterInfo1, dwSize, &dwSize, &dwCount);
 
for (DWORD dwIndex = 0; dwIndex < dwCount; dwIndex++)
    TRACE("]%s[\n", lpPrinterInfo1[dwIndex].pName);
 
delete [] lpPrinterInfo1;
