Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
I am creating an SDI to plot a picture pixel wise using pDC->setpisel()
I have a large 2D vector which is generate in PLOT button in a dialog . On pressing the 2d vector is generated. How will I pass this 2D vector to ONDRAW(CDC*pDC). So that i can process further the vector and put as pixels using for loop.. I donot know if ::Postmessage could workout.. How to use it if it does so??
I would be highly thankkful for ideas and sugestions

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
Easy. The vector belongs with your app document class. Document is accessible from your view any time.

But how do i call the ONDRAW () from the ONBUTTON() in dialog class.. The vector was declared and created ONBUTTON function itself.. Actually it reads a text file and geenrated the vector..
I am bit new to visual C++ 6..

You must never call OnDraw directly. Instead, you call pView->Invalidate().

And again, the vector belongs with your document class. This is your data to make drawing on.

Yes that is true but pView->Invalidate() doesnot work.. It shows undeclared identifier

Then set up a pointer to your view as a member of your dialog and set it before you call DoModal, or pass the view's pointer in as the parent of the dialog when you create it, and call GetParent from inside the dialog.

What is a pView and where do you call this line from?

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
I have push button () in dlg.cpp file..There I have generated the vector by reading a text consists of number for calculations..
pView i declared there.

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
For eg in the

//Do the operations
pDC->SETPIXEL(i,j,RGB(values,values,values) //I get values from VECTOR

Where "there"? :confused: And how?
And what does it have to do with a pointer to existing View class object?
BTW, did you ever hear there is a lot of samples in MSDN, also for SDI with Doc/View architecture?

The vector has to be accesed in ONDRAW() which i will be using to calcute RGB values and use them in plotting pixels. I hope the problem is clear now..
Yes during my search i could find those links but I donot know those links donot work.. I think in this country it doesnot work...

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
You're not listening to the advice being offered. That tends to stop the help from coming.
As mentioned, data belongs in the document class.
Your dialog needs access to your view so it can invalidate it. I told you a couple of ways to set that up.
In OnDraw, call GetDocument() to get the data from the document object.
If you're going to ask for help, you should listen to it.

I did look at it. At this point all I can really say, and I don't mean this in a bad way as everybody starts somewhere, is you're not understanding some very fundamental concepts of OOP and doc/view architecture.
Do you understand classes and their member variables?

Again, the vector should be a member of the document class. It should not exist in the dialog class.

yess yess and i do understand that.. It was sucessful what u had suggested..
I need an if condition in ONDRAW() so that when i call invalidate if (invalidate is called) then follwo the plotting instructions;
Now How to acess the vector in ONDRAW()...
Please donot mind. from last 10 days I am struggling.. May be in confusion state i am asking silly questions.. I am in learning stage also and beginner.. Gradually once I pickup and understand it i will be able to do..

You show us no real project. So we have to answer with something that you have to adopt in your code some way proper for your real code. In case you're not able to do that, you're stuck, no matter how sorry you are about this.
To have a conversation both sides must speak the same language. So, please put aside your current project and try to analyze the sample Victor recommended you, as well as other samples from MSDN site. Play with the samples, modify them and see what effect your changes cause. Buy (or lend from somebody) some books on MFC programming and work those through. When you understand the concept, please come back, you're always welcome.

Ok I followed all the instructions as given.. All codes compile successfully without any errror. But during execution it gets stuck.
I found that this statement makes the loop stuck and ends the SDI
pDoc->RGBVector.push_back(temp)
pDoc- is a CContourPlotDoc pointer declared in CONTOURdialog (userdefined) header file inherited from CDialog class
RGBVector- declared in CContourPlotDoc.h file which stores the RGB values in vector
temp is RGB value vector 3*1 and pushed into RGBVector
It is done so that I can access the RGB vector in ONDRAW()
Is there any syntax error. or the methodology is wrong??

Once it is updates the vector declared in Document.h I can acess it in ONDRAW()

But you failed to use code tags when posting code. The code you posted is unreadable without proper use of code tags.
Second:
Code:
LPTSTR lpData = new TCHAR[500];
ZeroMemory(lpData,500*sizeof(TCHAR));
You're using vectors all over the place, so why did you not want to use it here? Because of this, your code has a memory leak every time you call OnPlot.
As a matter of fact, all you need to do is declare an array since you know the size already:
Code:
TCHAR lpData[500] = {0};
pEdit->GetLine(0,lpData,500);
If for some reason you wanted to use vector:
Code:
std::vector<TCHAR> lpData(500);
pEdit->GetLine(0, &lpData[0], lpData.size());
Either the array or vector version will not cause the memory leak.

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
First. The code is almost unreadable because of using no code tags.
Second. What is pDoc- > RGBVector definition?
Quote:
Code:
std::vector<int> temp;
temp.push_back(R);
temp.push_back(G);
temp.push_back(B);
pDoc->RGBVector.push_back(temp);
Third. RGB perfectly fits into 32bit:
Code:
COLORREF temp = RGB(R, G, B);
EDIT: the latter means, there's no need to pile arrays on arrays. BTW, it seems you never care about cleaning RGBVector.

For calculation puroposes i need values and so do i store it in vector format.. I have attached a screen shot as weel as i have quoted the code. Please have a look.

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
Why are you declaring vectors in your dialog? Stop it. As I said before, it's really clear you're missing some fundamental concepts, more than can be introduced and explained in forum posts. Stop what you're doing. You're over your head. Spend some time learning how MFC, doc/view and dialogs work, and spend some time learning the basics of OOP. You can't learn this stuff by guessing and trial and error. It's too complicated.

That doesn't address the issue about the memory leak.
How many times is OnPlot() called? Multiply that by 500 (or more) bytes, and that is how much total memory is leaked by that function. So if the function is called 1,000 times, that's 500,000 bytes leaked. Sooner or later, your app will die due to the memory leakage.
There is no need to be using new[] in that OnPlot() function. Either declare a regular array, or use vector<TCHAR>. It makes no sense to use vector everywhere and then not use it for what vector was designed for.

Paul McKenzie

ONPLOT() is not called repeatedly. On pressing the PLOT button in a dialog box designed it starts executing the codes writen to generate the RGB vector.
Further I would like to make a note that when i remove this line
Code:
pDoc->RGBVector.push_back(temp);
everything works fine..Loops and all run fine.. Nothing gets stuck ..

Maybe this is the main point. Declaring a pointer never means you're allowed to use it uninitialized. Declaration doesn't do any magic, it just allocates some memory and instructs compiler about what type it is. You must fill it with the address of your doc class before first use. Man, seems GCDEF is right, and you have to get back learning pointers before doing anything real.

And you're going to keep getting mad because you're trying to do too much too soon. There is a HUGE learning curve with C++, MFC, OOP and Windows programming, especially when you try to do them all at once as you are. I would expect it to take months to learn all you need to learn to do what you're trying to do. If you're expecting to bang this out in a day or two, you need to adjust your expectations.

Then why did you ignore to learn something using MSDN samples I referred to in one of my previous posts?

Can you suggest me some good books or tutorials where i could understand. I followed up some books like Visual C++ in 21 Days and some such books.. There I just find how to add something and plot something .. but i dont find as simple i am looking for..
MSDN tutorials are not working. May be that could have been benficiary but bad luck...its not working in this country

You showed a lack of very basic understanding in C++, not handles or MFC classes. But you cannot expect to understand MFC or any other framework without good knowledge of C++ basics. I would suggest you to switch to some other language, like VB.NET or C# (Express version from MS is for free!), where the learning curve is not that steep.

Well, MSDN works just fine all over the world, in US, Russia, Japan, Israel, Europe but fails to work in India. Very bad news.

Whatever you're related to, any branch of engineering or science, computer, mechanical, whatever, you cannot skip learning basics. BTW, no matter what language you eventually choose, start reading books more solid than "..in 21 days" crap.

I can suggest you to make use of Search here on CodeGuru. There are lots of recommendations already made before, and there's no need to duplicate that.

If you didn't install VC++ samples then could search for their download in MSDN. For example, here you could find "Microsoft Visual C++ 2008 Sample Library"...
PS you have to learn using MSDN and other Web search. Try Google, it will help you! :rolleyes:

Re: Pass a vector from a pushbutton in dialog class to ONDRAW () in the view.cpp
Heloo every one.. The problem is solved. I designed the SDI and I got the results as i wanted. Thanks every1 to the hints given by every1.
Special thanks to GCDEF who gave the main hint for solving it. I could understand how to use it. I guess learning visual C++ is sit and solve any problem then get practiced to it
Thanks every1
