Hi everybody. Long time no messaging. I got an easy question. How can you make a window with a thin (2D) border? BECAUSE I DID THIS IN THE PAST! Less than 3 weeks ago! And now I can't do it any more. It's incredible! I'm totally frustrated! I tried combining so many flags that I think I went through all the possible combinations except the right one.
Take for example this simple way to create a window in a standard Win32 application. This shoud create that 2D window but it's still 3D!!! I remember that in the past when I removed that WS_THICKFRAME attribute, it looked 2D. But it isn't working any more. Aaaaaaaaargh!!!!!
<br />
LRESULT CALLBACK WindowEngine (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)<br />
{<br />
return DefWindowProc(hwnd, uMsg, wParam, lParam);
}<br />
<br />
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)<br />
{<br />
MSG Msg;<br />
WNDCLASSEX wceData;
HWND a;<br />
<br />
wceData.cbSize = sizeof(wceData);<br />
wceData.style = 0;<br />
wceData.lpfnWndProc = WindowEngine;<br />
wceData.cbClsExtra = NULL;<br />
wceData.cbWndExtra = NULL;<br />
wceData.hInstance = hInstance;<br />
wceData.hIcon = NULL;<br />
wceData.hCursor = LoadCursor(NULL, IDC_ARROW);<br />
wceData.hbrBackground = NULL;<br />
wceData.lpszMenuName = NULL;<br />
wceData.lpszClassName = "testClass";<br />
wceData.hIconSm = NULL;<br />
RegisterClassEx(&wceData);<br />
<br />
a = CreateWindowEx<br />
(<br />
NULL,<br />
"testClass",<br />
"Some title",<br />
WS_OVERLAPPEDWINDOW &~ WS_THICKFRAME,<br />
10,<br />
10,<br />
100,<br />
200,<br />
NULL,<br />
NULL,<br />
NULL,<br />
NULL<br />
);<br />
<br />
ShowWindow(a, 1);<br />
<br />
while(GetMessage(&Msg, NULL, 0, 0) > 0)<br />
{<br />
TranslateMessage(&Msg);<br />
DispatchMessage(&Msg);<br />
}<br />
return 0;<br />
}<br />

Hi Richard. Nope, unfortunately it doesn't help. Did you try WS_BORDER with the code above? If you put that WS_BORDER style, the window will still have a title bar. There is not noticeable difference between WS_BORDER and WS_CAPTION.
Pf... totally weird. WS_POPUP | WS_BORDER creates something of a 2D window but I am definitely sure that I was able to create a window with caption, maximize, minimze buttons AND 2D ASPECT! And now I can't do it no more. Aarggggghh! I'm so pissed off! I gotta dug up from the grave some of my old code apparently.

I need a way of limiting the user to enter only integers. The code below goes in an endless loop if any character other than a digit is entered on the screen. I can not use the isdigit() or isalpha() functions as they can only be used for character types. How should I change my test condition to accommodate this? The data2 variable is of type int.
while ((data2 <= 0) || (data2 > 12))
{
cout << "Please subunit number: ";
cin >> data2;
cin.getline(buffer, 99, '\n');
}

Do you mean to have your range of valid values to be (-inf, 0) U (13, inf)? I think you mean to do this:
while (data2 >= 0 && data2 < 12)
{
cout << "Please subunit number: ";
cin >> data2;
cin.getline(buffer, 99, '\n');
}

I want to allow integers greater than zero and less than 12. Initially I used the && operator. But when I type in a number out of this range, it jumps out of the while loop and never asks me to enter a valid number. Oddly enough, it worked with the || operator with the screen prompting me as appropriate for numbers out of range. But the program fails in both cases if I type in a non-numeric value.

That will allow all integers below or equal to 0 or greater than 12, but reject anything that is from 1 to 11. What you want is: (data2 >= 0 && data2 < 12).

Personally, I'd let the user enter whatever and not read anything until he or she hits enter. After he or she hit enter I'd try and decide if what they typed was a valid number; doing something like
<code>
char buff[1024]; //whatever the user entered
unsigned int value;
int charsRead;
bool validEntry = false;
while(!validEntry) {
//prompt the user
//get a line from the user via whatever method...
if (sscanf(buff, "%u%n", &value, &charsRead) == 1) {
//can further compare charsRead w/ strlen if you want, ie
//test strlen(buff) == charsRead
//
validEntry = true;
}
}
</code>

That is what cin does ... with far less code.

Hi all could any one show me how to collect the bold part data from a webbrowser controle . I want to collect those data and place them in a listview and use the color code to color the name in listview. I be happy if some one show me how this can be done. The nubmer of rows in the table are dynamic.Thanks
Note: i want to extract the name and color1 and color2 data from webbrowsser controle as shown in pic
[IMG]http://i5.photobucket.com/albums/y180/method007/extractData.jpg[/IMG]
webbrowser html code:
<html><br />
<br />
<head><br />
<meta http-equiv="refresh" content="60"><br />
</head><br />
<br />
<br />
<p><ul><table border=1 cellpadding=4<br />
<br />

david i am new to visual c++ 6 . i came from visual basic 6 and it is hard for me to use that code. could u tell me step by step how to use that code. I do not know how to implement it. i already have an mfc form with webbrowser on it that loads a specific webpage .

You'll need this in your CDialog-derived class:
BEGIN_EVENTSINK_MAP(CMyDialog, CDialog)
ON_EVENT(CMyDialog, IDC_EXPLORER, 259 , OnDocumentCompleteExplorer, VTS_DISPATCH VTS_PVARIANT)
END_EVENTSINK_MAP()Then put that other code into:
void CMyDialog::OnDocumentCompleteExplorer(LPDISPATCH pDisp, VARIANT FAR* URL); After the DocumentComplete event has been received, the OnDocumentCompleteExplorer() method can then be used to extract the data.

Isn't your project a dialog-based application? Put the code in your CDialog-derived class (i.e., CFindUserDlg).

My project is MFC as u see in the pic . I have no idea where i have to put your code!!! what part should i put your code and what your does without listview !!!! see the pic and tell me wha should i do ? i am dong this in visual c++ 6.
unfortuney the way u explain is like i am 10 years experienced c++ prorammer which i am not ,i just started!!
[IMG]http://i5.photobucket.com/albums/y180/method007/project.jpg[/IMG]
could u just make a project and add a webbrowser with a html code that i gave u and show me hwo to extract that data and place it in listview.That way i do not have to explain over and over what i have in mind!!

I think you need to get more experience in general C++/MFC before doing this, Adding and Extracting HTML from a web browser is not a really complex task, but it needs to have some more knowledge.
have a look at those articles :
http://www.codeproject.com/miscctrl/#HTML+Browser+Controls[^]
it should help you a lot.

As I mentioned already, put the code in your CDialog-derived class (i.e., CFindUserDlg). If this is troubling for you, perhaps you need to start with a less ambitious project. It makes no sense to dive into a project such as this when even the basics of VC++ are new to you. Start with something simple so that you can get comfortable with the IDE. Otherwise you'll just frustrate yourself (and others).

David i do not have CFindUserDlg !!! as u see in that pic i have FindUserDlg.h and FindUserDlg.cpp . Which one and what part ? Furthermore, i do not see any part of this code refrencing a url . How it will do the work if it does not access a url !!!
<br />
You'll need this in your CDialog-derived class:<br />
<br />
<br />
BEGIN_EVENTSINK_MAP(CMyDialog, CDialog) //{{AFX_EVENTSINK_MAP(CMyDialog) ON_EVENT(CMyDialog, IDC_EXPLORER, 259 /* DocumentComplete */, OnDocumentCompleteExplorer, VTS_DISPATCH VTS_PVARIANT) //}}AFX_EVENTSINK_MAPEND_EVENTSINK_MAP()<br />
Then put that other code into:<br />
<br />
<br />
void CMyDialog::OnDocumentCompleteExplorer(LPDISPATCH pDisp, VARIANT FAR* URL);<br />
After the DocumentComplete event has been received, the OnDocumentCompleteExplorer() method can then be used to extract the data.

The files (FindUserDlg.h and FindUserDlg.cpp) contain the class (CFindUserDlg). Open the files to verify.

<br />
enum { IDD = IDD_FINDUSER_DIALOG };<br />

All
I have a situation where I want to use an environment variable in the path during linking with VC7.
A) is it possible to use environment variables in the path to your OutputFile in the linker options?
B) If so, what is the syntax to use an environment variable in the linkers OutputFile options.
Thanks for your time
Dave

|
|
|

Configuration Properties:
Output directory:$(PATH_OF_ENV_VAR)
Linker->$(OutDir)/$(ProjectName).exe
where PATH_OF_ENV_VAR is your env variable.
You may need to restart your machine.
similary you can use $(var) in other options also.
Hope these help.
Regards
Abhishake Lahare

Thanks Abhishake
I ended up finding it after some scowering of the documentation. The very important step is what you mentioned. The re-boot. You have to re-boot after setting a system environment variable. That held me up for about 20 mins too. 
Thanks again
Dave
