There is no vector in C, do you mean vector stl - Google Search[^]?

There is no vector in C !
Just arrays.

Advice read C documentation.

hi all,

i draw a image when i preview it its display ok but when i print with multiple page.

on first page its drawimage correctly but after first page it return generic error.

i really dont understand what happen here.

i m using this to draw image.

Graphics graphics(pDC->GetSafeHdc());
	Image myPNG(path);
	if(myPNG.GetLastStatus()!=Ok)
	{
		return FALSE;
	}
 Gdiplus::Status stat;
	stat =  graphics.DrawImage(&myPNG, (INT)image_rect.left, (INT)image_rect.top, 300, 300);
	return TRUE;

thanks in advance.

Where in your application is this code being called? Is it inside your OnDraw function, or somewhere else?

i m used it in

OnPrint(CDC* pDC, CPrintInfo* pInfo) function,

i really dont understand when i preview this image is visible

The only thing you can do is to step through it in the debugger to try and isolate what is happening.

is there any role of PageUnit or PageScale,

i u using
graphics.SetPageUnit(UnitPixel);

coz when i debug i dint recongze the problem,

in preview the image is display and when i print the error comes.
function is same for both.

Sorry, but as I said, the only way to track this sort of error is by using your debugger. There is nothing that anyone here can do to assist, as there is no useful information provided.

Sadly, that Generic Error is the ONLY error provided by GDI+, so debugging them can be a nightmare. Good luck.

Re: WaitForInputIdle parent process gets access exception

20-Mar-16 16:58

Hi
I am waiting for a child process to complete initialization so that I can get its window

handle

After I do CreateProcess

I use the PROCESS_INFORMATION pi parameter of The CreateProcess to WaitForInputIdle(pi.hProcess,INFINITE);

The Child process goes about its business intitializing in InitInstance returns TRUE

It has a message map

After the return TRUE from InitInstance, the parent breaks from WaitForInputIdle with a

Access Exception

Thanks

What you have detailed is correct and the recommended way to do it

So you therefore have a coding error which can be

(i) The launched process does not have a graphical interface ... must not be a console app which has no queue
(ii) The createprocess startup structure is invalid

If the launched process is yours you can go around the whole problem by using an Interprocess communication method.

If the launched process isn't yours check your code with notepad or something simple which that technique works with.

Thanks so much
I see all of the info of the startup structure can be ignored can I memset
The entire structure to NULLs

The .cb field is the only mandatory field which must be set to sizeof(STARTUPINFO);

You can memset it and then set the .cb field but it's just as easy to zero the variable creation

STARTUPINFO startupInfo = {0};
startupInfo.cb = sizeof(startupInfo);

your suggestion is fine as well

STARTUPINFO startupInfo;
memset(startupinfo, 0, sizeof(startupinfo));
startupInfo.cb = sizeof(startupInfo);

The Exception was caused by unrelated exception which I fixed WaitForInputHandle Works Thanks for your help

Checking my code seems I have already done that

embed WxWidgets in MFC applications?

Hi Everyone,

is it possible to embed WxWidgets Controls in a MFC based application?
In detail, is there a way to use wxWidget Controls inside a MFC Control? specially CView, CFormView or CDockablePane?

My problem:
I have a huge MFC appication with rich GUI features.
I need to extend this application with a feature, that user will be able to display application data by creating his own views.
I could start this task with an approach like this:
XUIFramework: A GUI Framework based on XML and MFC[^]

Actually it would work with some simple MFC controls, but there will be a lot of work to make it more functional.

So my basic idea is, to use wxWidgets because of its rich functionality. But I cannot rewrite the complete application to base it on wxWidgets instead of MFC.

An further advantage of wxWidget would be, that it should be very easy to create a runtime for other systems like linux to run the user's GUI!

I have found in internet a few comments about such an approach. some says, it could be possible. But I have not found anything concrete. If I would have a very basic sample, I could start such a project.

Any ideas?

How to Mix MFC Controls and OpenGL?

Hello,
is it anyhow possible to mix or overlay MFC Controls in OpenGL controlled screen area?

My aim is as follows:
I have 3D animation (like industrial robot visualisation). Nearby 3D objects I want to display object related information (e.g. with a CListBox Control).
I have already a lot of Controls, based on MFC Controls with enhanced functionality. I want to reuse this at top of a 3D scene?

Any ideas, if it is possible or how I should start?

Many Thanks

Richard

How to perform Expression Evaluation

Member 1239950317-Mar-16 8:32

Member 12399503

17-Mar-16 8:32

Write a simple expression evaluator that takes a string like the following as input: 1+2*(3+4).
-Only integers need to be supported
-The following operators should be supported: +, -, *.
-Expressions within parenthesis should be evaluated first.
-Then the resulting expressions should be evaluated from left to right (no operator precedence)
-Example:
4+(4-(2*3)+1)+4 = 7

The code should be written in such a way to support additional operators.

Assume the existence of a function tokenise, which could take a string and return an array of strings, for instance

tokenise(‘1+(2*3)+4’) would return [‘1’,’+’,’(‘,’2’,’*’,’3’,’)’,’+’,’4’]

and the functions isNumber and asNumber which would return a Boolean and integer respectively on a single string input.
