warning C4312: 'reinterpret_cast' : conversion from 'DWORD' to 'CMyClass *' of greater size

CMyClass* pMyClass = reinterpret_cast<CMyClass*>(arg);

arg is a DWORD

A DWORD is 32 bits. A pointer is 32 bits. So what the heck is the compiler telling me??? Confused | :confused:

Didnt you recognize that you have now a 64bit machine on your table? So the pointers are now 64bit instead of 32bit. Smile | :)

Hi everybody,

I would like to export data from a safearray to range in excel. So, ii've read the articles Q186120 which gives an explantion and an example to do it. I've tried to test it in my application, first i ve done simply in trying to put in a specific set of range the figure "1". But when i test it it doesn't work the only first cell ("A1") is filled by "1", WHY??? So, you could find the code i've wrote, so, if someone could help me!

Thanks in advance

I think your only settings the first value. Maybe the approch with the array is not the easiest way. If done this (where is the code???) with writing to a cell and the changing the position, it worked well.
Tip: if you write in a csv (comma separated file) with ";" as delimiter excel can open it easily. If you need you can also deploy a excel macro to some strange things.
If also read in CP an article about writing to Excel via ODBC Functions, it is working.

Ooops...sorry I didn't notice that.
How about using API's like SHChangeNotify or probably write a namespace extension (I know this may be too much .. but can't think of any API as such which you can use)
I guess the best option could be try to get your hands on FileMon from sysinternals (they have the source for that ) the solution in implemented as a vxd.

To kill a win32 app via batch file

Hi all,

I have a GUI win32 application.

When one instance is running I cann't run another instance because the application is communicationg with external hardware.
Before to run another instance of this application I have to close the running application manually.

Now I want to run this application a number of times with different arguments using a batch file.

Now I wonder how I can give command in my batch so that it can close the running application before next instance of appliction starts.

Batch file may look like:

1. Test.exe arguments
kill Test.exe (1)
2. Test.exe arguments
kill Test.exe (2)
and
so on

Hope I have explain my problem.
Any help in this regard
will be appreciated
regards

write a lil app (kill.exe) that accepts command line args of the name of the app to kill
in the kill.exe get the process id of the app to kill
send a wm_close message to it

make sure the app to kill will process those messages

Hi Lauren,

Thanks for reply.
I would appreciate if you or someelse can give me a code example of killing another application B from one application A.

As least how to get the process id of an applicatin and then kill that.
Further, I guess the kill.exe you mentioned should be a Win32 application so that it can take wm_close message.

thanks again for your help

How to print/Preview the static

hi could not you suggest how to manage the following:
I have written a program which gets data from database (Access, SQL Server)
the data are shown in static.
I need these all to be send to print/print preview or to MS Word.
one more thing: how to make some statics bigger in size and some small?

thank you
if you can help send please to bek79@mail.ru

Take a look in the printing section here. There is an example of how to print a long CString across multiple pages in a view. You just need to get he text from the static into the string used, and the rest should work automaticlly. This assumes that the test in your static control is multi-line.

Saving Application settings for next restarts

Hi!
Is there any well-known way of storing application (GUI) states, so that next time when it starts, it gets all the states and show accordingly?

Please let me know of the ways of doing it.

Thank you
Shri Ram Soni

It really depends on what framework or tools that you are using to develop your application.

If you are using MFC, then you are in luck, you can simply set the registry key that your app will store all of its settings in, then call WriteProfileString and GetProfileString from your CWinApp object to manage your settings.

If you are using any other tools there are most likely methods to help ease the trouble of saving your settings. Depending if you want to save them in an ini file you can use WritePrivateProfileString. Of If you want to save your settings in the registry you will need to open a registry key and create new settings.

Good Luck

Works under UNICODE ???

Daniel Strigl9-Oct-02 20:51

Does the following function work, if UNICODE is defined and when UNICODE is not defined?

I think that the line if (c != ' ') could be a problem!
Does this line works correct in both systems (UNICODE and non UNICODE)?

(This function should remove all spaces in a string!)

const CString CSerialize::WithoutSpaces(const CString str)
{
    CString strTemp;

    ASSERT(strTemp.IsEmpty());

    // Add all characters to the temporary 
    // string, that are not a space character
    
    for (int n = 0; n < str.GetLength(); n++)
    {
        TCHAR c = str.GetAt(n);

        if (c != ' ')
        {
            strTemp += CString(c);
        }
    }

    return strTemp;
}

Re: Works under UNICODE ???

Paul M Watt9-Oct-02 21:22

the ' ' will translate to a char that contains a space or 0x20, which is 32 in decimal. In order for this to work properly in Unicode, you will need to cast your ' ' to a TCHAR, which will give you this 0x0020. Here is an example:

<br />
if (c != (TCHAR)' ')<br />
{<br />
...<br />

This will basically expand the single BYTE char to a double BYTE wchar_t which is what the TCHAR is declared as when the UNICODE macro is set.

Good Luck

My first guess would be to change (c != ' ') to (c != _T(' ')) so the space is treated as a wchar_t in Unicode builds.
