Annoying, isn't it? I thought it was a little funny how he gave us an error code written in German and expected us to understand it, when this site is worldwide. Laugh | :laugh:

And yet, english is the dominant language. Why aren't we all writing in Chinese? Poke tongue | ;-P

babelfish and google have free translation services. Smile | :)

Ever heard of lingua franca? It was a term that began back when French was the dominant language. Everyone used French, to dicuss science, art, international anything.

When England became a world power dominating a fourth of the world's population, "the country that the sun never set on" or something like that, English became the dominant language.

America became the dominant world power, well, at least since the atomic bomb was created, but before that as well. Hey, they beat England to become free! Hence, the world speaks American English.

If the Chinese could become anything worth not laughing at, maybe we would be speaking Chinese.

Thanks for the tip on the translation services, though.

Someone said I should read the call trace to find a solution for this error. Well, there it is, but I don't understand it. The program which produced this error (stated above - translation just some post under my first post!!) is an empty MFC-app generated from the MFC-Application Wizard. I made NO changes to the code.

If you guys (BugDanny & toxcct) would have read my first posting and the postings from the other guys, maybe you wouldn't have judged me stupid and annoying.
No I am NOT a VC++/MFC guru like you might be. That's why I thought I could find some answers on this board.

I did read all the postings before I made my post. My post was intended as a comment on the mildly annoying, albeit funny way that you posted your error in German originally, since you seem to be able to write English as well and this is a worldwide slight. I did not judge, or even all you stupid. (This is bugDanny writing, from a computer a don't usually use.) Neither did toxcct, I don't think.

rncwnd wrote:

And that's all right. This is the place to come for questions. You do not need to be a VC++/MFC guru to post your questions in Enlighs on a worldwide site (see my earlier post on lingua franca) or to make a statement or comment along with your long stack call list.

rncwnd wrote:

And this is the perfect place to come. As another noted, I would suggest, if the error was produced just by using the MFC App Wizard, to redo the action in another directory and see if the problem reproduces. If it does, I would suggest uninstalling and reinstalling your VC Studio. Perhaps the program had gotten corrupted somehow. As an alternative, you could post exactly which selections you made in the App Wizard. Perhaps there were selections you made that put this program in this state. At the very least, someone might be able to reproduce your error.

I'm sorry if I deeply offended you. I did not intend my post to be taken that seriously.

Well, then I misunderstood you both and I'm sorry for that.
I didn't know that e.g. google translates of error messages are that good (I didn't want to translate the error message because I was afraid to give it a completly diferent signification...)!!!

My program works now. After I deinstalled VS and installed it again after a memory and hdd check... After a "new rebuild" of all my MFC-programs they worked again.
Sometimes computers drive me really crazy.

If your app was generated with the application wizard and you didn't change anything (at least, not intentionally), I'd suggest creating a new one in a separate directory and see if it produces the same error. If not, as I would expect, compare all the sources (*.cpp; *.h; *.rc) to see what's causing the problem.

Other than that, and according to the call stack you posted, the problem occurs while your dialog receives the WM_INITDIALOG message. From CWnd::OnWndMsg (the second item from the top of the stack), it's going to ATL::CRegParser::MAX_VALUE, which is weird and would indicate some corruption.

Hope that helps,

i derived my class XView from CListView. I set the mode to LVS_REPORT so that always the view is a table with Five columns with headers. Now i add values to the rows it works fine.

Now what i want is in one of the "client name" column there should be a facility to change the text on double click or so.

Thanks Rose | [Rose]

Header should rather be used for column-based operations, for example sorting (I'd however suggest HDN_ITEMCLICK for that purpose).

There are many examples on how to handle subitem edition in CListCtrl are here at the CP: http://www.codeproject.com/listctrl

Place your caption in the resource file (as with a classic button), then extract your text at runtime using GetWindowText. With an owner-drawn button, you will need to draw the text yourself.

administrative privileges of SCSI Pass through

Hello,

I am developing an USB pen drive app,
the program works well with XP(or 2000) administrative privileges,
but it doesn't work without it,
because the way I get the drive handle is(suppose the usb pen drive is E:\):

HANDLE hDevHandle;
char szDrive[]= "\\\\.\\E:";

hDevHandle = CreateFile(szDrive,
GENERIC_WRITE | GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL);

CreateFile fail without administrative privileges,
following is the description of limitation from MSDN:

You can use the CreateFile function to open a physical disk drive or a
volume. The function returns a handle that can be used with the
DeviceIoControl function. This enables you to access the disk's partition
table. It is potentially dangerous to do so, since an incorrect write to a
disk could make its contents inaccessible. The following requirements must be
met for such a call to succeed:
1.The caller must have administrative privileges.
2.The dwCreationDisposition parameter must have the OPEN_EXISTING flag.
3.When opening a volume or floppy disk, the dwShareMode parameter must
have the FILE_SHARE_WRITE flag.

item 1 cause the fail,
How could I get drive handle without administrative privileges?

Thanks,
Chandler

What about using the bullet character if your font supports it. • Like so. It's alt + 0149 or U+2022. Else you'll have to draw one yourself using GDI.

Any better solution to solve this?

I have one function with 3 parameters.
In that function I have one switch case statement which depends on first parameter of my function. Nearly the cases are 28 to 30. For each case there is another sub switch case which depends on the second parameter of my function with more cases. For different cases I am allocating different classes memory in one class object. At last the function returning that object. For this concept implementation is there any simple implementation or any other logic, any template. The cases are increasing because of new implementations. Expecting some better solution.

The sample code is:

CMyCls* CEmr:GetCls(DWORD dwDId, DWORD dwClsId,BOOL bFe)
{
      CMyCls* pCls = NULL;
      switch (m_byClsFamily)//data type is BYTE
      {
            case _FAMILY_1_:
                  switch (dwClsId) 
                  {
                        case 0x8242:
                        if (bFe || (dwDId == DB_18C453))
                              pCls = new CMyCls1;
                              break;
                        case 0x8252:
                        if (bFe || (dwDId == DB_18C452))
                              pCls = new CMyCls2;
                              break;
                  ...
                  ... 
                  }
            break; 
            case _FAMILY_2_:
            ...
            case _FAMILY_3_:
            ...  
            case _FAMILY_4_:
            ...
            ...
            break; 
      }
return pCls;
}

Here All CMyCls1, CMyCls2, CMyCls3, CMyCls4,... all are derived from a class named "CMyCls".

Any help very thankful to them. It is urgent.

Nice talking to you. Blush | :O

How to Disable/Hide Mouse Cursor ?

Amarelia29-Sep-05 22:36

Amarelia

29-Sep-05 22:36

Hi
I have asked the same question but I didn't get any satisfactory answer, so I am again posting it here....

I have a dialog based MFC application in which I have used Microsoft Web Browser ActiveX control through which I allow user to navigate the sites.

Now if I want to hide cursor, I have used SetCursor(NULL) and also tried ShowCursor(FALSE) but the problem is : When I move my mouse with little bit of speed, it shows cursor and then again hides...what seems to be the problem, HOw to overcome it ?

Or is there a way to disable mouse ? So I don't have problem of hiding cursor.

Thankx in Advance
