I solved the problem; it was something real stupid: that picture control, that I used to place child dlg on parent dlg, was set to be visible - it occured to me that is should be put as "not visible" - and all is all right now.
thank you all on topic for help.

Hi All,
I had a general query regarding modal dialogs and child windows.
Is there any way by which I can restrict a CDialog instance to be
within the client area of a parent window and yet also allow DoModal method
to work correctly ?
From what i`ve seen so far, such dialogs show the CWnd value passed to them
in the constructor as the parent/owner in Spy++ but can still be moved out of it when
the modal loop starts.
Doing a SetParent causes both the parent and dialog to hang when i call DoModal.
Thanks in Advance.

Hello,
Change the style of the dialog as "Child" from the property window and now try.
but DoModal won't work fine I think because when you do "DoModal()". the parent window being disabled thus the all of it's child windows will be disabled and you will not be able to operate anything within the new window you're showing. But the dialog will be restricted inside the parent's client area. Why you can't use Modeless dialog?

Hi David,
That sample looks interesting....i`ll try tweaking the GetOwner and SetParent part right now 
|
|
|
|

Hey Guys,
Thanks to David`s sample I found a "fix" for this issue...
u need to set the owner in the initdialog function and also manage
the visibility state urself. This, along with the code to restrict
the dialog`s movements makes it feel as though its an actual child window
and also keeps DoModal working.
Thanks to all for the help.
Appreciate it I do.

Hi,
I'm trying to use the 'inet_addr' function to convert a char IP address, but I think since the IP Address i'm passing in to the 'inet_addr' function has leading zero's (192.169.055.075), the 'inet_addr' function is interpreting this differently. Any suggestion on how to remove the leading zeros?
Thanks
char IPAddr[20]; //192.169.055.075
ulAddr = inet_addr(IPAddr);

Indeed, according to documentation, numbers with a leading zero are parsed as octal.
Provided your format is fixed (as it looks) you may use
int a[4];
char c[20];
if ( sscanf("192.169.055.075","%03d.%03d.%03d.%03d", a, a+1,a+2,a+3) == 4)
{
sprintf(c, "%d.%d.%d.%d", a[0], a[1], a[2], a[3]);
}
eventually c[] contains the address without leading zeros.

It would be greatly appreciated if anyone could point me towards a good serial communication class and demo running in a thread. I've found quite a few but none are fitting my needs.
Thanks!

This is again related to the Listboxes in VC++ MFC. I have a listbox containing the list of parameter names which are retrived from a text file say XXX.txt.In this XXX.txt,the values are stored in the format as given bellow.
Parameter No1.
Parameter Name1.
Parameter Value1.
Parameter No2.
Parameter Name2.
Parameter Value2....and so on...
So for example it is as:
1
abc
ee34
2
rtrt
ff45
.
.
.
and so on..
So now among these values,all the parameter names are listed in the particular listbox. Now using this listbox,if I double click on the a particular parameter name among the list listed in the listbox,that parameter name must be retrived from the listbox along with its parameter number and its parameter value which are available in XXX.txt text file and should get stored in another text file say YYY.txt.Similarly I must be able to do multiple selection of parameter names from the listbox and store all of them along with their parameter number and parameter value at once in YYY.txt.
Can anyone suggest me how to go about the above problem.

You should associate the number and value to the name when populating the list box.
Here's how you can do it.
Create a structure having one member for number and another for name.
When reading the first name, create an instance of the structure and initialize its members.
For example when "abc" is read, the created structure instance will contain "1" and "ee34".
Use the CListBox::SetItemDataPtr to associate the structure instance to the index where "abc" is inserted.
To retrieve it you would then use CListBox::GetItemDataPtr to get an instance of the structure.

I'm just going to take a stab in the dark here and hope someone has some information about this.
We need to move our development environment inside of Citrix. Unfortunately we are still using Visual Studio 5.0, and haven't been able to upgrade due to compatability issues with third party software we are using.
I cannot get our project to build inside of Citrix. I get an "Error executing Link.exe", with no other errors at all. The first thing it's trying to build is a static library, and I can see that it creates all of the .obj files, but apparently never creates the .lib and then the Link.exe error occurs.
Just to eliminate the possibility that my large project can't find something it needs, I created a new "Test" workspace, created a new static library with just some comments in it and built, and outside of Citrix it builds fine, but inside Citrix I get these results:
Compiling...
Test1.cpp
Creating library...
Error executing link.exe.
Lib Test.lib - 1 error(s), 0 warning(s)
Then I tried a new .exe, just accepted all the Wizard defaults and tried to build, and also get the same type of error in Citrix:
Compiling resources...
Compiling...
StdAfx.cpp
Compiling...
ChildFrm.cpp
MainFrm.cpp
TestMFCApp.cpp
TestMFCAppDoc.cpp
TestMFCAppView.cpp
Generating Code...
Linking...
Error executing link.exe.
TestMFCApp.exe - 1 error(s), 0 warning(s)
So it kind of appears that I'm unable to build anything inside of Citrix. I thought it could be a permissions issue, but I now have Admin rights and am still getting the same error.
So I have a feeling there may be a compatibility issue with our old version of Visual Studio in Citrix, and unfortunately Microsoft doesn't support 5.0 anymore, so I'm afraid we may be in a bit of a bind. (I.e., my development may come to a screeching halt when they move all of our servers next weekend).
If anyone has any information about this and/or knows of any potential workaround to try, I would be most grateful.
Thanks in Advance.

'need'? Is that because your IT department/management have told you that you have to? If so, not being able to update a (mission-critical?) app is probably good leverage for keeping your current development setup
It appears that your problems are with linking - is it possible to see if a later linker works a) under Citrix, and b) with VC5?

The reason we 'need' to move to Citrix is that when our app runs it connects to various databases, and all of our database servers are being moved across the country (instead of being housed in the same building where I work). So... outside of Citrix, I'd still be able to write and build code, but to do any sort of debugging or just running the app to see if things are working would be painfully slow. So, it seems like for perfomance reasons, we're almost going to need everything to be in Citrix.
We've asked about potentially keeping a test server here with some fake copy of the databases we're using, just enough for us to be able to run with... But were told flat out "NO".
So... How would I go about trying a later linker? Thank you.

What about building external to Citrix, deploying to a network drive available to Citrix and using remote debug between host & Citrix?
AmVal wrote: So... How would I go about trying a later linker? Thank you.
To get a later linker, copy link.exe from a later install of Visual Studio. To try it out, I'd create a makefile from your VS project (you could do that in VS5.0, yeah?) and use that. Before running the makefile, add the directory containing the link.exe to path in front of the Visual Studio directories.
I'm afraid it's difficult to be of much more 'help' - I moved off VS5 about 10 years ago, and haven't used anything older than VS2003 since about 2004.

Well, I did discover that when I try to build in Citrix, I am getting some failures/errors showing up in the Event Viewer. The Security tab shows a Failure Audit related to Privilege Use. And the System tab shows some TermServDevides Errors.
I've been put in the Admin group and had the C drive completely opened up to me security-wise, but I still get those errors.
Others who are building with newer versions of Visual Studio aren't having any problems at all.
Any other ideas how to get around that???
Otherwise I will probably start looking into Remote Debugging, which I'm not familiar with. I hope I can find that for 5.0!

Try Debugging Tools for Windows[^] - that's pretty much independent of the Visual Studio version (and is very useful to have around anyway!).

Hi
I did following:
CBitmap *pBitmap = Gdiplus::FromFile(wfname);
Gdiplus::Graphics gr(dc);
gr.SetPageUnit(Gdiplus::UnitPixel);
gr.DrawImage(pBmp, p, 3);
The image drawing is very slow. How can I improve the image drawing? how can I force image be loaded into memory?
Thanks,
|

By doing this:

only once maybe ? Make the pBitmap variable a member of your class and load the bitmap from the file only once.
