refresh problem in tabs

There are 3 tabs in my application. On opening the application the 3rd tab will be in focus. When i try to resize the tabwindow, 3rd will be in focus but the contents of 2nd tab will be displayed. After switching between the tabs the tabs will get refreshed. How do I solve this refresh problem?

How are you setting the default tab to the third tab at startup?

By using SetCurSel()

TCM_SETCURSEL does NOT cause a TCN_SELCHANGE message to be sent, so when you use
SetCurSel(), you are responsible for making sure the correct tab window is
positioned and shown within the tab's "client area".

A couple of weeks ago I enabled XP's automatic updates (it hadn't been upgraded since I installed XP SP1 a year ago). After the upgrade (XP SP2 and it also did some secuirty upgrade to my VS2005) I cannot build any of my code anymore. At first I got a bunch of errors, then I retarted my machine, at which point there was an error message on boot up that I've never seen before, immediately followed by an "automated" fix. Now when I try to recompile again it still doesn't work, but the errors are different.

I can't find where HDROP is defined but the error concerning DragAcceptFiles is strange. afxwin2.inl calls this function with 2 arguments but it's defined in afxwin.h with only one. How is this possible? Were the header files changed during the updates?? If they weren't how did it EVER work?

Thanks.

you have to derive the class from the CEdit and handle the WM_LBUTTONDOWN message and plant your new popup menu there!

What is bad in handling the OnKeyDown/OnKeyUp and calling the scroll if pressed key is PageUp/Down??

There are two tabs in my application. One is the parent and the other is the child. The parent tab is CView and the child tab is the CEdit control. Page up and page down are working for the parent but not for the child. I tried to implement ur suggestion but still page up and page down isn't working for the child.
Thanks

Ok, in that case it is not going to work. I had the same problem and an easy solution I found (is not the best, I know it) was to declare Hot Keys with the VK_ that I wanted to check in other views. The Hot Keys are global in the app, but locally executed. For me worked. Take a look on that.

How to use command line arguments in a win32 application?

Sauce!14-Jul-08 21:14

Hi guys,

I am trying to implement some command-line arguments for my application. I would like to be able to run the program with "Program.exe -w800 -h600" to force the resolution to be displayed at 800*600.

I've come up with this basic code that I would have thought could achieve the goal I had in mind but I get the error

error C2446: '==' : no conversion from 'const char *' to 'int' There is no context in which this conversion is possible

So lpCmdLine is a pointer to a const char, so how do I extract the information I want from it? Wouldn't it have been easier for microsoft to just implement it as an array of char's? Frown | :(

WINDOW_WIDTH and WINDOW_HEIGHT are both global integers.

// Get command-line parameters
for (int n=0; n < (sizeof(lpCmdLine) / sizeof(char)); n++)
{
    if(lpCmdLine[n] == "-" && lpCmdLine[n+1] == "w")
    {
        char w[4];
        w[0] = lpCmdLine[n+2];
        w[1] = lpCmdLine[n+3];
        w[2] = lpCmdLine[n+4];
        w[3] = lpCmdLine[n+5];
        WINDOW_WIDTH = w[];
    }

    if(lpCmdLine[n] == "-" && lpCmdLine[n+1] == "h")
    {
        char h[4];
        h[0] = lpCmdLine[n+2];
        h[1] = lpCmdLine[n+3];
        h[2] = lpCmdLine[n+4];
        h[3] = lpCmdLine[n+5];
        WINDOW_HEIGHT = h[];
    }
}

The solution probably has something to do with some hefty use of pointers Frown | :(

You should use atoi[^] if you want to convert a string (e.g. "800") into the corresponding integer.

sorry but I don't think that will work for my purposes Frown | :(

I need to be able to parse the string first for any - signs followed by either a w or h. Once I get that working then I would be able to use atoi to convert the numbers in the string but I can't get to that point using atoi Frown | :(
