In moving over my code, I'm now to the MFC Wizards that we created.

We used to create a property page/sheet and call SetWizardMode to activate them, but alas, that feature is no longer in .NET

So, what is our replacement feature/procedure for this? I created a form, threw in a tab control, but could not find a way to hide the tabs.

Any thoughts?!

I read that one in my research and it really didn't tell me anything. Just a kludge work around.

But talking about kludges... I hid the tab controls under a panel and life is nice again. Kludgie, but nice.

I know there is a Wizard component available, but I really don't want to spend $160 just to hide a tab.

Not bad. Did you set the tab position to bottom and added a panel with Next, Finish, Back etc. buttons?

Please Help...Tree Refreshing Problem

8-Jul-02 11:39

Yep!

First off, changed the tab control to display tabs on the left.

Then, I added 4 panels total. One on top for the heading, one on bottom for the next/back, one on right for balance, and one on the left to cover up the tabs.

When I want to see the tabs, I send the left panel to back, when I want to hide them, I move the left panel to front.

Works pretty darn well.

Hi,

Does anyone know if there is a function in C# that will refresh a TreeView? I know this function existed in J++ but does it exist in C#? I want the jobs that get added to the node to be listed alphabetically without having to rebuild the tree again. If I quit the program and then reexecute it again -- they appear alphabetically.

If anyone knows how I might achieve this without having to rebuild my tree I certainly would appreciate. Thanks.

cAptHiDDeN Eek! | :eek:

Just guessing...

MyTree.BeginUpdate( );
... (add nodes) ...
MyTree.EndUpdate( );

I'll tried that before -- close but no cigar. Anyone else know if this is a bug? It would certainly be nice if these were sorted. I am sure someone will figure it out eventually. Let's all hope so.

I am using the tree at this very moment and it refreshes just fine on it's own alphabetically. I think you must be creating the nodes wrong or something. Do you have the sorted property selected to true? It works just perfect though.

anyway peace

Any word on next version?

Damn...all that I had to do what change the sort property from false to true. I just hate it when its something that simple -- and you think it would be something more complicated. It would have been nice if J++ version 6.0 was this easy!!! hehehe

Thanks for the help.

C# construct similar to JTable

8-Jul-02 9:07

Curious if anyone's heard when the next version (or service pack) of .NET/C# is due? And does anyone know of anything new that will be in it?

Thanks!

Hi all,

In Java swing, JTable lets users modify the content of each cell and different types of construct can be associated with each table cell, eg. a drop down list, string and so on. So it is extremely flexible.

Could anyone please tell me if there is similar class available on C#? I have searched the internet for a long time and couldn't find one. Is there any workaround to handle this situation?
very much appreciated.

Extending a control used by VS Designer

I want to extend a control (MenuItem, to be specific). But I want Visual Studio's Windows Forms Designer to use my new control (call it MyMenuItem) instead of MenuItem when using the Designer to create a MainMenu.

How does one do this?

Thanks in advance!

Unless the MainMenu designer has this feature in there already you'll have to create your own MainMenu type class and designer so that it creates MyMenuItems instead of MenuItems.

porting from c to c#

8-Jul-02 6:35

I am porting some code from c to c# and the original code makes a lot of use of #define macros - is there an equivalent in c# - at the moment I am turning the macros into fuctions but it I am wondered about the performance aspects of doing this

There is no equivalent to macros in C#

Creating them as functions should work well; the JIT does a good job of inlining such functions.

thanks eric (got your book by the way Smile | :)

what about optimisation? I am doing a lot of bit wise operations and rotations in 8,16, and 32 bit blocks

at the moment I have

private static uint ROL(uint x, int n)
{
return ( ((x) << ((n) & 0x1F)) | (x) >> (32-((n) & 0x1F)) );
}

private static uint ROR(uint x,int n)
{
return (((x) >> ((n) & 0x1F)) | ((x) << (32-((n) & 0x1F))));
}

would these be optimised to IL equivalents or would I have to drop to some IL layer eg is there an equivalent of _asm

You could consider compiling the library with Managed C++, and making wrapper-classes to the library, it might save you a lot of work. Managed C++ seems quite able to cope with plain C.
