Removing the scrollbars from a CFormView derived class

Hello,

I have an Microsoft Outlook style application - a splitter window with a TreeView derived class in the left pane, and , at different times, one of various CView derived class in the right pane.

When the user resized the main application window, eventually the CFormView derived class will display scrollbars. I'd prefer for it to never display scrollbars. Can this be done? How?

Regards,
Sternocera

If the control bars appear, it means that some working sufrace of that view is not being displayed, so if you want to remove the controlbars, you may lose some working area in your view.

Possible, it is possible, but I don't know why do u want to.

I can think on 2 possibilities.

First one... Change the visible area with SetScrollSize ()

Second one... take the moment you want with WM_SIZE, take a pointer to the scrollbars and disable/make them not visible.

Greetings.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Help me to understand what I'm saying, and I'll explain it better to you

This has done it for me:

void CsplittertestView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit();

SIZE mysize; mysize.cx = 1; mysize.cy = 1;

SetScaleToFitSize(mysize);
}

Thanks,

I can't find anywhere to add a grid to my dilog window.

Is this due to my older version of c++?

What am I missing here?

hi there,
i have coded an aplication that talks to a relay board via the parallel port on my pc,it has eight relays on it that effectivly turns things on or off upon recipt of a command.
so what i want to be able to do is set an on and off sequence for each individual relay on the board,using some sort of timer as a trigger.
i think i will need eight timers that are in sync with the sytem clock and will trigger when the values match

can anybody point me in the right dirction as how to achive this

If you are using MFC, take a look in CWnd::SetTimer (...) and KillTimer (...)

without MFC i have read the function sleep sometimes, but to make a pause I dont know if it triggers code

Hello

I have written a small application which reads the registry keys present in a .txt file and tries to export each key using regedit, i.e. I read each line of the file (which is a key) and using the commandline for regedit (regedit /e "target file" "source key") I export it into a folder creating a new .reg file for each key read from the file.

Now in my .txt file there are around 11,500 keys. The keys are successfully exported till 5450, but after that calling CreateProcess on regedit returns error no. 1450 (no system resources) and all the subsequent keys are not exported into the target folder.

What could be the reason for this error to come up? And how should I change the logic so that this error doesnt come up and all the 11500 keys are exported as different .reg files into my target folder?

Thanx.

Are you closing the processes after each one is used. Windows has a resource limit of 10,000 resource handles 10,000 limit[^](or something like that) per process and if your spawning outside processes, they may count against your main process. I'm not sure how the rules work with spawned processes.

However, be informed that a resource handle can include pens, brushes, windows, etc... and depending on the type of windows or controls being created, you can hit the resource limit pretty quick.

Try closing things that might maintain handles to resources once you are finished with them as it sounds like their being maintained somehow.

Here are some links about resource handle limits...

Is this a console or a GUI application? If the former, check out getch(). If the latter, check out the WM_CHAR message.

What type of project did you opt for? With a console application, it'll likely contain one of each, making editing them about as easy as it gets.

allooba wrote:

Both, since everything is technically code. Files with a .h extension typically contain declarations, while files with a .cpp extension typically contain definitions.

Hi All,

I have created the project of MFC Activex Control and also I have included other project as a DLL in the same solution.And my Activex project is depends on the DLL project.

Here First of all I want to ask you that is it possible for the Activex project to depend on DLL project? Is there any other setting I have to make?

And now when I compile the project it gives me the error like......

Project : error PRJ0050: Failed to register output. Please ensure you have the appropriate permissions to modify the registry.

In my DLL project I have made some registry operations.How can I get appropriate permissions to modify registry? OMG | :OMG:

Thanks In Advance.

Log in with a local administrative account and try again would be the simplest approach. By default, not involving discussion of any type of UAC, only certain accounts have modify or write rights to HKLM and HKCR and it sounds like your not logged in with one of them or your IT staff has made modifications to the standard registry rights settings.

If you on a Windows Vista box with UAC turned on, you will potentially get some false positives if your not familiar with what is going on under the hood.

Thanks For Reply,,

As you told to login in local Administrative,But I am already working in administrator Account.

And my other confusion is that is it possible that IO can add other DLL in the solution in which Activex project is the main project.But here my Activex project depends on DLL project.

Thanks.

Is not going to be easy. You have the structure of the ListCtrl in your FormView, but in the preview... you will most probably need to do the work by hand.

About the example, some days ago there was a question about CListCtrl, I already answered with the initialization of the Report mode with variable width for columns.

See here[^]

By the way... take a look in the articles too. There are very good examples here[^]

if you're talking about this[^] article, then 2 things :

1) when you have questions related to an article, ask it on the forum directly at the bottom of the article, so that the autor will be answering you directly.

2) BTW, looking at the code (yes, even you you can open the zip files), this class inherits from... CMultiColorStatic.

I don't know much of the later, but it inherits itself from CStatic; but as i said previously, you'd better ask the article's author.

Any practical experiences of VirtualAlloc v.s. malloc? From MSDN, I can not find any comparisons between the two methods.

VirtualAlloc is more efficient.

malloc is a C library function interface, it is implemented by calling the OS API. More in "programming applications for ms windows" by Jeffrey Richter
