Im tying to cat an integer, such as zero. I am basically trying to count from "0000000" to "99999999" but everytime I set 'int i = 00000000" it shows up as just '0' how can I set the start value as '00000000', so that it will count as "00000001, 00000002, 00000003" and so on?

I figure if it is only going to count as zero, I guess I should count the number of values that it has counted and cat the zeros on to it. The first start was to set and array as "unsigned long int aArray[] = {0,00,000,0000};"" and so on, but that doesnt work.

For an integer, 0 or 00 or 000 etc. are all the same.
What you're saying is the way you want to visualize it.

That can be done while printing using printf.

printf("%07d", ival);

Or while converting it to a string in MFC.

CString cs;
cs.Format("%07d", ival);

is there a way to output visually using namespace std;, I havent used printf in forever

Try this:

int main()
{
   for (int i=0;i<10;++i)
      std::cout << std::setfill('0') << std::setw(7) << i <<std::endl;
}

If you mean using C++ streams, you should be able to it like this -

cout << setw(7) << setfill('0') << ival;

How can I correct MFC focus problem after closing HtmlHelp window?

26-Sep-09 7:11

I got it all worked out, my overall output is:

// intStr_cat.cpp : Defines the entry point for the console application.
//
//#include <>
#include "stdafx.h"
#include <conio.h>
#include <iomanip>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	unsigned long int o = 99999999;
	for (int i=0;i<o;++i)
      cout << setfill('0') << setw(9) << i << endl;

	getch();
	return 0;
}

Hi,

I need to get the logo of the user and put it in my application. But it should be of about 5" X 5" and jpg/bmp type only.

How do check these specifications in the image? I am using VC++6/MFC

Thanks,
Tara

You may load the log image usign a CImage object (taht is able to load both formats) and then check (or just adapt) the size.

I'm having a problem with an MFC app. I open a modal dialog, press F1,
HTML Help pops up with the appropriate context sensitive help. I close
the Help Window and can then press any shortcut key (such as Ctrl+O
for open) and the app will open the file open dialog, even though the
modal dialog is still visible and should have the keybord focus.

I'm using the new MFC feature pack.

This behavior can be duplicated with a stock MFC application. Using
the MFC Application Wizard, build a SDI app with Context Sensatvie
Help. Leave all other options at the default. Build and run the app.
Open the Help About dialog, Press F1, Close the Help Window, press Ctrl
+O, you'll see this issue.

If after closing the Help Window you click the app window or dialog
box with the mouse the focus is set properly and pressing shortcut
keys does nothing.

It appears that this might be a defect in the new MFC featrue pack
classes. Does anyone have an idea as to how I can correct this
behavior?

Thanks.

Who created this feature pack? Maybe you should tell them about it.

Google map from lat/long

My program generates a latitude and longitude and I would like to display a map of the area with the exact location marked.

Is Google Maps the best way to go for this?

At the moment I do not want the map to be embedded in my program. I would be happy just to spawn the default web browser passing it a maps.google.com URL that would display the correct Google Map with the location marked accurately.

Is there a page which describes how to construct the necessary URL ?

Also, do Google allow this sort of use for free, or would their terms require a fee for programs which spawn the map in a web browser like this?

Does this[^] help?

Why not embed a browser (IE? WebKit if you're feeling ambitious) in your program? That'd be cool!

Thanks, that's a great help. Embedding a browser sounds interesting - I'm still using VC++ 2003, would that be too old to use WebKit?

Is there anything else provided by Microsoft that can be used to create a web browser within a program's window?

Stuart Dootson26-Sep-09 11:59

Note: WebKit is the open-source HTML engine used in Google Chrome and Apple Safari. It is wrapped in a class in the Qt library.

No - but other than Qt, I'm not sure of easy ways of using it.

IE. Use the MSHTML ActiveX control. It's pretty simple and (if you've already got an MFC program running) probably easiest.

Thanks, I'll look at that. When I created ny project originally I did not have ActiveX ticked in the project wizard. I don't relish the thought of recreating the project from scratch, so is there a simple list of changes I can make manually to the project files that would add ActiveX support?

Incidentally I found a reference to Microsoft's CHtmlView which I think is a wrapper around the ActiveX control - and also a CHtmlCtrl which allows CHtmlView to be used in a dialog window. But there seemed to be comments about memory leaks.

Would it be easier/safer to go for the ActiveX control itself - I guess this is

http://msdn.microsoft.com/en-us/library/aa752046%28VS.85%29.aspx[^]

or to go for the CHtmlView/CHtmlCtrl solution?

Stuart Dootson26-Sep-09 13:09

26-Sep-09 13:09

I would have thought that CHtmlView/CHtmlCtrl would wrap the ActiveX control. I'm not sure what's required for ActiveX support in MFC - I've only used the Web Browser ActiveX control in WTL, which doesn't require you to enable ActiveX support at a project level.
