They only work if you execute the action in the blank area of the control.
Probably tree control enters into modal loop when you click on items and move the mouse a little bit. In such case, messages are processed internally by routine deep inside comctl32 - you'll be unable to process them without hook.
You should handle NM_CLICK and NM_RCLICK instead.

CListCtrl
What message is passed about when the little box is being drawn to select a group of items? Or is there a message that I can respond to when a new item is selected as part of a group of items being selected in such a fashion.
Thanks!

Check LVN_ITEMCHANGING and LVN_ITEMCHANGED.

Hi,
I created a setup using the a setup project in Visual C++ .NET Standard, which works absolutely fine on the dev box, but when I try a vanilla install of Windows 2000 it complains saying it needs the .NET framework installed.
Surely MS Installer 2.0 doesn't need the .NET framework?!
Any help very gratefully received.
TIA.
Paul.

Maybe not, but perhaps your program does!

Hi Nish,
Thanks for the reply.
Nope, that's not it. We also tried adding the .NET framework MSM, which didn't do anything.
The setup complains before the program is even installed (when the setup.exe is first clicked on).
Paul.

Hmmm.
This is a wild guess, okay! But in most installers we can set the option to check for some bare minimums. For example you can set the minimum requirements to Windows 98 or say you can insist on IE 5.5 etc...
Maybe somewhere in your installation settings you have enabled the .NET runtime requirement. Thus the installer sees that the runtime is not installed and it stops!
If this was a stupid guess, please forgive me. I am just making a long shot in the dark.

As a long time C++ programmer, I find VC++ far superior to Delphi for the kind of work I do.
Delphi is a little too focused on RAD for my way of developing.

choosing either Delphi or Visual C++ depends largely on what you are doing.... although C++ executes faster, Delphi compiles in a single pass which means it will always be faster than MSVC, and most other C/C++ compiler out there.... Delphi is also based on the Pascal language, but borland have their own version, Object Pascal, which supports most features found in C++
if you want to do database programming, or large GUI-based programs (using windows common controls and such), Delphi is by far the best choice. if you plan on creating games or other performance-critical applications, C++ is probably a better choice (i am not saying Delphi is slow in any way here, because it isnt). if you want to learn programming, Delphi is far easier to learn than Visual Basic and outperforms it in just about any circumstance (Delphi executables also dont need a DLL with the runtime libraries in it to run either, but that option can be activated to produce tiny executables....)
I actually have both Visual C++ and Delphi and use them both often - which one you use depends on what you want to do (although i prefer Delphi for it's ease of use....)
in the end, it's up to you....

We do database applications and large GUI based programs, but we use VC++ because we can make very small distribution packages which is critical for us as we do all business via the internet so our clients must download the program as we do not send any software on CD.
I don't know anything about Delphi, but I'm thinking on difference might be that a setup for a Delphi built business application versus a C++ built one would be much larger.
Is that the case?
|
|

|

No. MFC apps are generally much larger than Delphi apps. If you want small C++ apps, use WTL.

i'm not exactly sure which produces smaller exe's, but delphi can create standalone versions which don't rely on msvcrt.dll or similar libraries, or a library-dependant version (which chops a lot off the output file's size, but then it needs the runtime library dll, standalone versions only link with parts they need so they're usually smaller and simpler when installing on an end-user system.... the library dependant version rocks for development because it size is comparable to MSVC, Borland C++ and even, dare i say it, VB. smaller files means i have more hard drive space, which is an issue for me at the moment, being a 'poor student'......
personally i think the output file size difference wouldn't be worth comparing - Delphi was designed to develop business applications quickly (how many games were written in Delphi? not many compared to Visual C++) and it does that task well. from a beginner's point of view, its also a lot easier to learn and use (i learnt it first) - C++ has a bit more power than Delphi, but i've never needed any features that C++ has and Delphi doesn't. once again i guess it comes down to personal choice and experience...
btw, i'm only 17 years old (last year of high school in australia), so i dont have much experience writing business apps - if anyone from melbourne/geelong area wants to change that you have my email address...

That is not true! Delphi is OOP designed, has classes, inheritance and exceptions, and VCL si a GUI class library similar to MFC. You cannot say the same thing about vb

It was a joke!
Although the original Delphi was very close to what I said. However it has evolved very nicely but is still too GUI centered for my tastes.

Okay. Let's say Delphi would come somewhere in between VB 6 and VB.NET
That's a fair compromise I guess

I had the misfortune to write a Delphi based app a few years back - I always hated the fact that you had to explicitly call class constructors with Delphi - truly gross.
