A CButton is a Window, WIndows have Rect (GetWindowRect() function). Rect gives you height and width. So it's not a straightforward as posted but easily obtainable.

Sorry, the other poster is right. Use
CRect rect;
m_Button1.GetWindowRect(&rect)
rect.Width()
rect.Height()

Assuming the coordinate system is correct (Client View, Control View, Screen View), which is a big assumption at this point, the line
m_Button1.MoveWindow(myRect.right, myRect.bottom, seems to want to put the left edge of the button at the right edge of the main window, therefore, it's not visible since it's off the right side of the main window. Similarly for the y coordinate, you're putting the top of the button starting at the bottom of the window, therefore it's outside the viewing area

The first two arguments to MoveWindow are the new X and Y coordinates of the upper left of the window. You are putting all your things at [5,5], on top of one another. No wonder it doesn't seem to work.

Hi,
I have a piece code which I wrote several years ago. This code was written on a XP system with VS2005.
The code worked fine and in fact the existing .exe still works fine on some machines.
Now, this code seems to work on some machines and not on others. I suspect the difference between target machines in 32 or 64 bit, though that may be totally wrong... The development machien is 32 bit XP machine and the machine on which it fails is a Windows 2008 Server R2 64-Bit.
The code will still CoInitialize's and connects just fine and the 'logging in' also works.. Its the call to:
hresult = ptrRS.CreateInstance(__uuidof(Recordset)); // E_NOINTERFACE error
which fails.
This is a snippet of the code:

Hi!
I have don this thing before using VC++ and MFC. But my new owner  don't want to use VC++. So I decided to port the whole thing to Win API. Generally this should be easy, but I have problems with the DLL part somehow.
When I make a basic DLL with only the dll_process_attach and just the initalization and some mouse handling, the DLL works! But when it's got basic TLS code to save my custom control class address for multithreadding support, it just don't work. The test app isn't start at all - and it isn't shows up in the TaskManager. AND where I got confused. If I comment all the added lines it still not change a thing. Even if I clear all generated files and recompile.
Did someone do this before? Dose anyone have a template to this? I confused because I did done it in VC++ and it's working.
Please help! Thx!

Ok! The basic problem is solved. I have forgotten to change the class name in the resource.
Btw the TSL thing isn't working how it's presented in the Win API programming help file. So if someone has working solution for DLL with TSL - or a way to store an address of the class for every thread - I need it badly!
Realy, I don't know if I need to do this TSL thing for running different instances of a control, but if not, then how to store the class's address?
Thx for any help!

Hello Friends
I am creating a map of key as string and data is of One class Object reference.
As i am inserting data into map as i am getting new string,so before loading new object I am deleting last object.but As i delete object,It is clearing from map also.
Here is the sample of code
class Test
{
int a;
int b;
}
map<string,Test*> mapTest;
As I run a loop of my some condition
On adding every new string that is some file name i am reading file values into that class.
Test* obj = new Test();
for(.......)
{
...
...
reading File int obj pointer
And then inserting into map
mapTest.insert(make_pair(string,objTest));
}
delete obj;
obj=NULL;
Any Suggestions.
Thanks & Regards
Yogesh

But If i dont delete then it is eating my memory.
As i my Class Size is too Long bcoz I am using for reading a file.

Well, how exactly do you expect to process the information in your objects if they are not in memory? If your application is memory constrained then you need to reduce the requirements by reading and processing your file one record at a time.
|
|
|
|

Hello,I agree with you that for memory constraint i need to create one object and processing should be done.I was doing this previously.
But my requirements are changed i need to keep in memry until application doesnt close.So that if user chooses same file I dont need to read it again.
This is the scenario.
Any Ideas.
Thanks & regards

Think about this logically: you need all the records from the file in memory at the same time, so the laws of physics state that you will consume record_count x record_size bytes of memory at minimum. The only alternative is what I suggested earlier, read in only the records you need at any one time. The overhead to do this is unlikely to be great enough to cause you any major problems.

Hello
I am totally agree with you Mr. macCutchan.
And we were doing like that but now Requirements are changed.

Well you need to look at your design as there is no way you can have this data in memory without it using space in memory!

because map keep reference to memory allocated to the object, since you deleting the obj afterward the actual memory got deleted and reference in map just point to deleted memory!.
if memory is not constraint you can create copy of memory variable when inserting into map!,however at the time of clearing of map you have to manually delete memory associated with the variables.

Thnks Alok,But my main constraint is memory here only.
Is there any other idea to erase memory after i use in map?
As you told map keep reference of object pointer.
Then how can i use map as a storage container of class objects.
Is there any other way to store class objects in some STL and then delete tht newed class object.
Bcoz otherwise if we dont delete then heap memory will get full or memory leaks.
Thanks In Advance.

it's depend on the way you implement the collection class, in your case your container is of string and object pointer.

see if you want anything readily available, it should be present in memory,see if you delete the newly created class-object using new, the object is lost till you have copy of same available for you. there is no way AFAIK to have something with having nothing.
Now, this a design issue not programming issue, so you can relax  , design can be created only if i have full requirement otherwise there always flaw in design which can lead to defects

First, when you delete an object using a pointer then other pointers, including the copy you stored in the map, will not be changed - instead they will then point to invalid memory. Trying to use them causes undefined behaviour. In short: don't do that!
Second, don't store pointers, store the objects instead. That way you'll save one pointer entry per entry, and the map will destroy the objects once you remove the entry from the map.
Third, from other comments I've gathered that you cannot actually afford to keep the whole map in memory. If that is the problem, then my best advice is: do not try to program that! Instead, use a database. The only alternative would be to selectively remove rarely used entries from your map and reread them later, when needed. But that would be inefficient, if the file you are reading is not itself indexed in some way. not to mention that such a paging mechanism isn't exactly easy to implement. A database however has these mechanisms, and rereading individual records back into memory later is fast.

For discussion sake, if we kept object instead, still it will create copy of original object (see it call copy constructor,if not properly implemented, there can be problem of shallow copy and dangling pointers), however the only advantage i know would be you don't need to worry about destruction as OOPS by heart take responsibility of destroying of object!

You're right, of course, but I deliberately left out these details as they didn't appear to be relevant. There's many ways to deal with this, and the best probably would be to make a map of smart pointers, but that would require even more memory, and since that appears to be the main problem here I didn't bother to suggest it.

Hi Developers,
Today I ahve faced a strange issue, that my application is gettong crsshed in release exe but not in debug mode.
The scenario is that i am clicking on the items of a tree controls very rapidly. It is searching functionality & top searched (from the user) has given on the tree. Code of click event of that tree is mapped like this
ON_NOTIFY(NM_CLICK, IDC_TREETOPSEARCH, &CRepLiveSearch::OnClickTopSearch)
And the function is here.
UINT uiFlags = 0;
const MSG* pMsg = GetCurrentMessage();
CTreeCtrl* pTreeCtrl = (CTreeCtrl*)GetDlgItem(pNMHDR->idFrom);
CPoint point(pMsg->pt);
pTreeCtrl->ScreenToClient(&point);
HTREEITEM ht = pTreeCtrl->HitTest(point, &uiFlags);
CString szSelWord = m_suggestionTree.GetItemText(ht);
szSelWord = szSelWord.Left(szSelWord.Find('('));
m_edSearch.SetWindowText(szSelWord);
*pResult = 0;
Can u tell me what may be the problem.
Thanks.
Amrit Agrawal.
