Thanks all for the time taken (again!). I managed to get this far cribbing code from here and there. I am virtually there in what I want to do - it's very basic...

A1 : D4 - a 4x4 grid. I can update any value no problem. When all cells are populated, I need to drop the first column, and move the remaining 3 columns along. The VBA for this is...

Range("B1:D4").Select<br />
Range("B1:D4").Cut Desitination:=Range("A1:C4")<br />
Range("A1:C4").Select

My interpretation (using the API) is

lpDisp = sheet.GetRange(COleVariant("B1") , COleVariant("D4")<br />
range.AttachDispatch(lpDisp);<br />
range.Select();<br />
range.Cut(COleVariant("A1:C4"));

and I get 'Cut method of Range class failed'.

Any chance of you spoon feeding me this last bit please?

Cheers

Dialog (Modal) based MFC Application, fails to respond properly to 'Minimize-All', 'Restore on click from taskbar-entry', etc

Hi,

This has been troublign me fors oem time now.

I have an MFC Application which is Dialog-Based. My 'main' is constructed of initializations and a 'DoModal()' for my dialog, this is AppWizard generated code.

My problem is that my application (or rather dialog window) :

1. fails to respond to the 'Start+M' key-combination (minimize all)
2. when clicking the 'Show Desktop' icon in the quick-launch bar my application disappears, but re-appears when any OTHER application is restored.
3. fails to minimize when clicking it's entry in the task-bar (it dose maximize if it was previously minimized.

I've tried looking at CFrameWnd's implementation for help, but can't find the specifics on this one.

Can someone help ?

Thanks very much Wink | ;)

The dialog will need the WS_MINIMIZEBOX style.

Creating and saving to a file

Hi,

I have a program that sends messages over the internet. I now need to change it so that i can save the messages to a file. Can someone tell me how to read from a file, open a file, and save to a file?

In my app, all my windows come up from drop down menus. So where should I open the file ?(once I know how) In the main class or the class where all the messages are made?

thanks

Jimmy

You'll probably want to create a CStdioFile object if this is going to be a text file. Otherwise, if the messages belong to the document, take advantage of serialization. Most everything is already in place so it's fairly painless.

Hi,

Can you explain a little more for me? What do you mean that the messages belong to the document? What is serialization?

Did I do something wrong by asking the question yesterday and today? is that why you put the link to my question yesterday? If so, sorry.

No, I was just making you aware that a previous attempt was made to point you in the right direction.

I'm guessing that you have either an MDI or an SDI application. If that's the case, it's bound to have a CDocument-derived class. That class will have member variables, which might (it's up to you to decide the most appropriate spot) include the messages you are creating/sending/receiving.

Serialization is well-documented in MSDN (this tool should become part of your arsenal). Here's an excerpt:

“Serialization” is the process of writing or reading an object to or from a persistent storage medium, such as a disk file. MFC supplies built-in support for serialization in the class CObject. Thus, all classes derived from CObject can take advantage of CObject’s serialization protocol.

The basic idea of serialization is that an object should be able to write its current state, usually indicated by the value of its member variables, to persistent storage.

David, I am sorry, I didn't know where to go with the help i got yesterday. i thought maybe i would get someone to shed some light on how to understand it.

Hi people! Smile | :)

I´m starting with GDI+ , so I discovered that I have to lead too much with
the WCHAR type OMG | :OMG:

. I´ve got some problems trying to compose a string (using sprintf ) and drawing the resulting text using Graphics::DrawString() (I couldn´t convert a char *string to WCHAR).

Do you know a way to make this convertion , or to compose a WCHAR string just like using sprintf?

Thank you ! Big Grin | :-D

run batch file contents from application...help experts

Dear All,

I am developing an application in MFC VC++ Version 6.0 for Windows 2000.

I have some contents in a batch file to uninstall my driver.
I need to uninstall the driver without using this batch file, i need to uninstall it from my application only on click of an event. Can any body please tell me API to uninstall the driver using the contents of the batch file

The contents of batch file are:

rundll32.exe setupapi,InstallHinfSection DefaultUninstall 132 .\filespyw2k.inf

I tried using Winexec like

WinExec("rundll32.exe setupapi,InstallHinfSection DefaultUninstall 132 .\filespyw2k.inf",SW_SHOW);

but it showed that installation failed. If i run the batch file it easily uninstalls the driver

Feel free to ask any further queries in this regards,

Thanks
Rohit Dhamija

It's just a guess but the InstallHinfSection() appears to have the following signature:

void InstallHinfSection( LPCSTR, UINT, LPCSTR );

If that's indeed the case, you could do something like:

hLibrary = Loadlibrary("setupapi.dll");<br />
pFunc = GetProcAddress(hLibrary, "InstallHinfSection");<br />
(*pFunc)("DefaultUninstall", 132, ".\\filespyw2k.inf");<br />
FreeLibrary(hLibrary);

Or you could just call CreateProcess() using the name of the .bat file.

My original hypothesis was wrong. It's a documented function. Big Grin | :-D

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/setupapi/setup/installhinfsection.asp

Now you can just link with setupapi.lib and call the function like you do any others.

Having just #include "Setupapi.h" is not enough for a complete, working program. For a Windows program, you'll need #include <windows.h>, too.

This setupapi.h file assumes the presence of other .h files. For example, line 37 is trying to create a new type (*LPGUID) based on an existing type (GUID). If no other .h files have been included that define GUID, a compiler error is just around the corner.

I think David means

#include <windows.h>

is required too, before the include of SetupAPI. (I hate it when I forget to tick the "Do not treat <'s as HTML tags" box too!)

Hi all,
I am trying to convert MS DOC file to tiff file. How to do this?.I need to build the application on my own and not rely on third party applications.
Thanks in Advance,

I'm not quite sure I understand the requirements here. Why do you want to convert a DOC file to a TIFF file? One is an image format and the other is not. Word itself does not even have provisions for saving as TIFF.
