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

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".

So, how do I solve this refresh problem now?
|
|

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.
------ Rebuild All started: Project: NSMAnalysis, Configuration: Release Win32 ------

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.

Have you searched CP for "CEdit context menu"?

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

There is a MDIchild window which has the CEdit class. Initially page up and page down keys were working.On setting the virtual key codes for page up and page down, page up and page down is not working. How do I enable the functionality of Page up and page down

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.

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? 
WINDOW_WIDTH and WINDOW_HEIGHT are both global integers.
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

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
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

Your code has several flaws.
Try
int iLen = _tcslen(lpCmdLine);
for (int i = 0; i < iLen - 2; i++)
{
if ( lpCmdLine[i] == _T('-'))
{
if (lpCmdLine[i+1] == _T('h'))
{
WINDOW_HEIGHT = _tstoi(&(lpCmdLine[i+2]));
}
else if (lpCmdLine[i+1] == _T('w'))
{
WINDOW_WIDTH = _tstoi(&(lpCmdLine[i+2]));
}
}
}

It took me a few minutes to understand your code (had to search through all the help files for all that stuff I've never seen before)
It looks like it should work.
But it doesnt
error C2664: 'wcslen' : cannot convert parameter 1 from 'LPSTR' to 'const wchar_t *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
error C2664: '_wtoi' : cannot convert parameter 1 from 'CHAR *' to 'const wchar_t *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
error C2664: '_wtoi' : cannot convert parameter 1 from 'CHAR *' to 'const wchar_t *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
And could you please give me some hints as to why my code is flawed? I was already aware there was something wrong with it, hence the reason it doesn't work.

OK. These errors arise because the LPSTR nature of lpCmdLine. Use:
int iLen = strlen(lpCmdLine);
for (int i = 0; i < iLen - 2; i++)
{
if ( lpCmdLine[i] == '-')
{
if (lpCmdLine[i+1] == 'h')
{
WINDOW_HEIGHT = atoi(&(lpCmdLine[i+2]));
}
else if (lpCmdLine[i+1] =='w')
{
WINDOW_WIDTH = atoi(&(lpCmdLine[i+2]));
}
}
}

thankyou, your code works flawlessly.
Bloody legend :P
Now, may we discuss the bad things I did in my original snippet so that I may learn from it in the future? That would be nice

Your original code:
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[];
}
}
1. sizeof(lpCmdLine) = sizeof(LPSTR) = 4 (on 32 bit systems). You should use strlen(lpCmdLine) instead.
2. Since the code inside the loop accesses lpCmdLine[n+5], the loop itself cannot run on the whole lpCmdLine's range available.
So the loop controlling condition should be (n < strlen(lpCmdLine) - 5) to
prevent buffer overrun.
3. You wrote your own version of atoi, but it is wrong: suppose pCmdLine[0] to pCmdLine[3] containing the right input for the number, the (brute force and simplified) code for a atoi-like function may be
int value = 0;
value = pCmdLine[0]-'0';
value *= 10;
value += pCmdLine[1]-'0';
value *= 10;
value += pCmdLine[2]-'0';
value *= 10;
value += pCmdLine[3]-'0';
