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.

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

webbrowser html code:
<html><br />
<br />
<head><br />
<meta http-equiv="refresh" content="60"><br />
</head><br />
<br />

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!!

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

Greetings:
I have long been aware of how difficult working with property sheets can be, but whenever I get down to having to deal with one, it never fails to amaze me just how awful they truly are...
Anyway, I set out to make a property sheet where the pages can be re-ordered. Can't do that, I know, so I set out to make it so that if I wanted to insert a property page into the sheet that was NOT at the end, I would actually remove the pages AFTER the point where I wanted to insert the new page and then re-add the pages that were already there.
This worked fine until I tried to INSERT a new page at position ZERO. It seems that if I remove ALL of the pages from the sheet, the property sheet spontaneously commits suicide. Isn't that nice? Who at Microsoft thought that this would be a good idea? What is so wrong with a property sheet that is blank for a few microseconds before it is populated or repopulated?
Can anybody lend some advice here, if not sympathy would be accepted. I really need my property pages to be ordered in a certain way and I will have to insert new pages and also re-order existing ones.
Thanks in advance,
Mark, Toronto

Hi Again:
Shortly after sending off my rant, I realized that my delemma had a simple solution:
In any case of inserting a page, including in the ZERO position, add the new page first, then remove all of the pages that you want to have positioned AFTER the new page. Then just add them all back.
Adding the new page FIRST ensures that the property sheet is never naked.
That's my story.
Regards,
Mark
PS: I still think that property sheets are stupid...

I'm looking for a control that incorporates both CCheckListBox / CDragDropListBox. I've attempted to use CDragDropListBox code from this site (non OLE version) but I'm having some problems after moving a list item and attempting to "check" that item.

Hi All,
I am facing high performance problem when working with CListCtrl with owner draw data and styles.
When i am inserting around 5000 records it takes more time. I want to avoid this delay. My idea is insert around 100 records initially and in background insert the remaining records. So user no need to wait till insert operation completes. Which is the best solution to solve this type problems.
Different ideas in my mind are
1) Use thread function to insert the data as background process
2) Insert the data into the list control when user scroll the list
3) Use the Peekmessage and Pump message instead of going for thread.
Please suggest me the solution/suggestion if any one faced like this problem.
Thanks.
Jerin
