Post the code here. looks like a DDB issue. Should be using DIB if you ever want images to be printing on the printer.

this is part of my code:

Does VC++ 2005 Standard include optimizing compiler ?

I'm looking to upgrade to Visual C++ 2005 Standard and wanted to know if it includes the same optimizing compiler in the Pro edition ?

With VC++ 2003, the Standard edition did not initially come with the optimizing compiler, although this was later released for free as part of the VC++ Toolkit.

The Visual C++ 2005 Express Edition definately does so i'd take a pretty good guess that the Standard edition does as well.

<edit>Yup, it does...[^]</edit>

Mnemonics/Shortcut Key Problem

FYI, I am running Win 98 with Visual C++ 6.0.

I am writing a WIN32 Application that has 3 edit boxes with 3 static text controls. I want the user to be able to enter the keystroke "ALT-1" and be placed in edit in the first box, etc. I am creating all my windows in the WinMain function. Everything works ok when the window is displayed initially, but if I "ALT-TAB" to a different window or minimize the window then the "ALT-1" key sequence stops working. The same problem exists for the Menu shortcuts ("ALT+F" for example)

I looked at handling the WM_CREATE message but I am not sure that will really resolve my problem because it looks like WM_CREATE is handled even before WinMain is executed? I am pretty sure my problem is because I am creating all my windows in WinMain but I am unclear/uncertain what action I should take. I also don't know exactly what I should look for/search on at the MSDN website. Confused | :confused:

I know there is something I am doing wrong I just don't know what it is....

Any ideas/suggesions are appreciated Smile | :)

Thanks!

RegisterHotKey()

Re: Mnemonics/Shortcut Key Problem

David Crow9-Jan-06 3:38

Mnemonics and hot keys are not the smae thing. You need to call RegisterHotKey() if you want ALT+1 to be seen by your applicaton even if it does not have focus.

Thanks! So if I don't want ALT+1 to be used/see by my app when it does not have the focus what do I need to do? Should I be using an Accelerator Table? I thought accelerator tables were only for shorcut keys (keys that would correspond to a menu option (CTRL+O for Open) can they also be used for things other than menu options? I am confused by the terms shortcut keys, accelerators and Mnenmonics. Are they the same thing or are there differences?
Thanks for your help! Smile | :)

An accelerator is a keystroke or combination of keystrokes that generates a WM_COMMAND or WM_SYSCOMMAND message. Although accelerators typically generate commands that exist as menu items, they can also generate commands that have no equivalent menu items.

A mnemonic is a selected letter or digit in the label of a button or in the text of a static control. The system moves the input focus to the control associated with the mnemonic whenever the user either presses the key that corresponds to the mnemonic or presses this key and the ALT key in combination. Mnemonics provide a quick way for the user to move to a specified control by using the keyboard.

MFC ActiveX Control Array Transfer

Hi,

I want to transfer an array from an ActiveX Control using a method. I have figured out that I have to set up a UDT, but I'm unsure on how to do this. I am writing the ActiveX in MFC C++ .NET

If I have the following struct:

typedef struct testArgs {
int test1;
int test2;
BYTE * test3; // This is a array
} test;

How can I get this to so that it is accessible in say Visual Basic .NET.

Any help would be greatly appreciated.

Setting an integer to the Array number as opposed to the array value

Hi,

I'm currently doing a university project for a resistor value selector program.

For this project, I have the program load in a series of calculated values into an array's elements. I now require my program to find the element of the array that has the smallest value and set an integer 'a' with the number of the element as opposed to the value it holds i.e.

SEL[0] = 2.3
SEL[1] = 3.4
SEL[2] = 0.3

I need the integer a to equal 2 not 0.3.

Any help would be great thanks!

This is a logical question!!! U can easily find better logic than this!!!

int MinValue = SEL[0];
int ArrayVal = 0;

for (int i= 0; i < ARRAY_SIZE; i++)
{
if ( SEL[i] < MinValue )
{
ArrayVal = i;
}
}

Sort the array, then set a to 0.

Question about icons

Hi,

I want to insert an icon into my application's resource, but every way I do it, it comes out ugly.

I extracted an icon from shell32.dll, and tried to import it into the icon editor of VC++ .NET 2003. However, the 32x32 32bit icon has an ugly black mask around it. If I open the same icon in Axialis IconWorkshop, the icon looks fine.

How would I normally get a 32bit icon in my resource, without having VC++ messing it up?

Re: Question about icons

You can insert any icon you like into your resource file, but don't try to open or edit it inside Visual Studio because it will screw it up. The icon editor only supports up to 256 colour icons. The icon will still work correctly in your application if you don't edit it inside Visual Studio.

You need to write an image editor as an embedded control in IE, then you need to write a web service to copy the images down to the editor, and to send them back up to save at the server.

A lot of work.

When you populate the control with the names of files, are you using FindFirstFile()?

Hi, how do you go about viewing the source code in a program that I have downloaded?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
