I just got this error yesterday with VS 2005. I thought it had been solved with SP1, but it hadn't. My solution was to access the class view from the header. Don't know why it worked.

I using Window CE API WriteFile() to write some barcode data to a file. Data is scanned and written to file ok. Problem is everything is on one line. How can I get the data in the file to be
line based. In other words, everytime I write to the file it writes a new line.
Thanks

Hi egerving,
The escape sequences for newline [^]in C/C++ is '\n'

If Randor's suggestion doesn't work, you should try writing "\r\n".

Using MFC & VC6
I am terribly confused about how to move CWnd objects around. With screen coords, client coords, dialog units, screen units, AaaRGh.
I have dialog app with button controls. From the OnSelect function of the buttons I am calling another popup dialog of my own making. I want to position the popup dialog so it obscure certain areas of the main dialog.
I am trying to use CWnd::MoveWindow() to move my popup dialog in the OnInitDialog() function to a position relative to the top left postion of the main dialog.
Which methods should I be using to get the main dialogs position to calculate coords for the MoveWindow() function in the correct units. A small example would be useful. Has anyone made a small Class to handle all this confussing translation between all the possible units and coordinte references ?

For that you want to use this route:
- Get the area of the main dialog that you want to obscure - this is most likely to be in client co-ordinates
- Convert to screen co-ordinates using CWnd::ClientToScreen[^]
- Now ensure that the child dialog covers that (screen co-ordinate) area. If you use MoveWindow, the screen co-ordinates are what you want to position the dialog
HTH!!!

Hi,
I already mentioned in my post i tried with vs2005..i want to get menu text when the user clicks any menu item in vs2005.
i am working with vc++6.0...please help me how to do this?

I suspect VS has non-standard menus (like Office….). I would use Spy++ (comes with Visual Studio) to see what messages ARE generated when you select a menu item.

use this function for get the menu item text,
GetMenuString();
Copies the label of the specified menu item to the specified buffer.
int GetMenuString(
UINT nIDItem,
LPTSTR lpString,
int nMaxCount,
UINT nFlags
) const;
int GetMenuString(
UINT nIDItem,
CString& rString,
UINT nFlags
) const;

I have installed mysql on my PC and created a database (sysops).
But I don't know how to connect and open the database.
I know how to use remote mysql, host (www...), user-name, password, database neme..,
What are connect info for local mysql?
Please help if you have experiences.

host is localhost or 127.0.0.1, rest all you should know.

Rest all you should know.
---------------------
I don't know.
Do you mean I need to create a user and password for the created mysql database?
|
|
|
|
|
Well you said you know how to connect to remote SQL so I assumed that you know about all parameters except host name.
No you dont necessarily have to create a separate user and password for every database. You can create a user in MySql and then assign it permissions to access a database. You can download MySql Gui Tools[^] to easily create users and databases.

i have one image file which contains 5 buildings ..i want to cut and save only the 5th building ,other four buildings are not shown in the image.
but when we are save the image 5th building not shown other four buildings are shown in the image...
this is my code snippet::
<code>
HDC pDC=::GetDC(0);
HDC TmpDC=CreateCompatibleDC(pDC);
CImage _image;
_image.Load(_T("//read.tif"));
int width=_image.GetWidth();
int height=_image.GetHeight();
HGDIOBJ TmpObj2 = SelectObject(TmpDC,(HGDIOBJ)(HBITMAP)_image);
Rectangle(TmpDC, 0,0, width/2, height/2 );
SelectObject(TmpDC,TmpObj2);
_image.Save( _T("D:\\newy.jpg"), Gdiplus::ImageFormatBMP);
::ReleaseDC(NULL,pDC);
</code>
~~~~~~~~~~~~~Raju~~~~~~~~~~~~~

So let me get this right, you open a tif file, draw a rectangle on it that is suposed to overlap some part of the picture and then you save the image to another file, right? (Btw why do you specify Gdiplus::ImageFormatBMP for the Save call while you are trying to save a jpg?) Your problem is that not the part of the image is overlapped you want? Why don't you move the rectangle then?

how to create one rectangle piece of image from existing image??
this is doubt

Ah well, create a new bitmap in memory with the required size, blit from the source image to the target image the part you want to cut out and then save this new bitmap.
So something like this:
HDC pDC=::GetDC(0);
HDC TmpDC=CreateCompatibleDC(pDC);
CImage _image;
_image.Load(_T("//read.tif"));
int width=_image.GetWidth();
int height=_image.GetHeight();
HGDIOBJ TmpObj2 = SelectObject(TmpDC,(HGDIOBJ)(HBITMAP)_image);
int newWidth = width/2;
int newHeight = height/2;
HDC NewDC = CreateCompatibleDC(TmpDC);
HBITMAP NewBitmap = CreateCompatibleBitmap(TmpDC, newWidth, newHeight);
HGDIOBJ NewTmpObj = SelectObject(NewDC, NewBitmap);
BitBlt(NewDC, 0, 0, newWidth, newHeight, TmpDC, 0, 0, SRCCOPY);
SelectObject(NewDC, NewTmpObj);
DeleteDC(NewDC);
SelectObject(TmpDC,TmpObj2);
::ReleaseDC(NULL,pDC);
CImage newImage;
newImage.Attach(NewBitmap);
newImage.Save( _T("D:\\newy.jpg"), Gdiplus::ImageFormatJPEG);
DeleteObject(NewBitmap);
I am not saying this code works or if it compiles at all, but it can be a starting point for you to get the idea, good luck.
