How do you find the application from the registry? Do you use HKEY_CLASSES_ROOT?

Now we are a bit off from my area, but if you know either CLSID or ProgId, there are functions for COM like ProgIDFromCLSID and CLSIDFromProgID. However, I don't know if they work for the guid in Uninstall-path. I've understood that for example Microsoft Office is just one entry in Uninstall but it has several com components for all products (word, excel etc).
AFAIK installer keeps it's own inventory under HKEY_CLASSES_ROOT\Installer\Products. Also all CLSID's are under HKEY_CLASSES_ROOT\ClSID. In products folder most products have Transforms entry and the guid in that seem to reference to the installation folder in SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.
That's about all I could come up with.

Hi
I am having a problem with the order of the columns in my data grid. I have set the order I want in the data grid property Edit Columns. When I run the project 2 columns are way out of position. I tried to move the out of position column using column order but it is ignored. I then tried coding the position using event private void GridDisplayOrder(). I listed all rows in order from left to right. I get the message object reference not set to an instance of an object. Not sure how to get around this error. Here is the event I use
private void GridDisplayOrder()
{
Grid_Property.Columns["pContract_NO"].DisplayIndex = 0;
Grid_Property.Columns["pProperty_ID"].DisplayIndex = 1;
Grid_Property.Columns["pVersion"].DisplayIndex = 2;
etc
etc
any assistance would be appreciated

You need VisualSVN[^] which is a plug in for Visual Studio.

I am going to create a custom control and want to add an ability. When it get focused then It appearance should change through GDI.
for example I am creating custom label.
Then how will i get my target.
Problem is that I am only able to change the object at Paint event, here I can make changes to my object through GDI but I want When my object get focus or it is being clicked then I want to make changes via GDI.
Any hint will be appreciated.

can you not just invalidate the control when you handle other events such as click?
userControl1.Invalidate();
this will cause the control to repaint itself, in which it will call the Paint event

is it C# support macro like c++? if not Why ? is it any standard they are following.
In C++ we can do MUL(X,Y) X*Y like this.

These are different languages, with different features, that's it.
This question is kinda like a holywar starter

0) Just because you *can* do something in C++, doesn't mean you should.
1) Macros can be used to circumvent the strong typing requirements of C++. Side effects are possible, and that's bad.
2) Macros cannot be debugged.
Macros that contain code are evil and should be avoided whenever possible.

Have to agree on all points. Macros are about the most evil feature C/C++ have to offer. The looong, late, sleepless nights dealing with macro expansion bugs...what a night terror.
All I can say is, THANK GOD C# doesn't have macros!!

Using macros, you can redesign your coding 'language' on the fly until your code doesn't even remotely look like C++. If you've seen as much bad C++ as I have, you know why many consider macros evil.

This is not a question, but is too short to be an article. Learn from my mistake.
Yesterday, I was testing a windows service I wrote using Visual Studio 2008 on a Windows 2000 machine. I had originally targeted .Net 3.5 when I created the project, and had to re-target the assemblies to 2.0 before installing it on the target machine. When I installed it, the event log would say that the service started successfully, but a few seconds later, I would get an error event - an invalid operation exception.
I removed EVERYTHING from the service except a keep-alive thread so it would keep running once installed, and it still threw the exception.
Thinking it might e a flaw in VS2008 when changing from .Net 3.5 to .Net 2.0, I tried creating an entirely new solution targeting .Net 2.0 from the start. It still threw the exception. And then I had an epiphany.
The installer class sets the name of the service. One thing that all windows services do (when you create them with the VS2008 template) is calls the InitializeComponent() method. I had always deleted this call in prior services I had written since it seemed like a pointless thing to do, but this time, I had left the call in. In InitializeComponent, it tries to set the service name to "Service1". This is NOT the name I gave it in the installer object. After changing the name to the same thing I used in the Installer object, it worked just fine - no exceptions.
When I changed the name of the service.cs file, I guess it missed that string in the re-factoring process. I spent four hours on this problem. BTW, the other fix for this would have been to NOT call InitializeComponent.
[EDIT] BTW, I had tested this service on my own Vista box, and it worked fine. While I was waiting for access to the Win2K box, I figured I'd fix the Service name (because it was showing up as "Service1" in the event log). I re-factored and compiled, but did not re-test it before trying it on the Win2K box (I figured the re-factor would have done what it was supposed to do). The lesson here? ALWAYS RE-TEST, NO MATTER HOW MINOR THE CHANGE IS PERCEIVED TO BE. This is proof that even the programmers with 30 years in the industry make the most rookie kind of mistakes every once in a while.

Regarding the current quality of the majority of articles, you probably would get a 5.

I don't think I've created a new Service with VS2008 yet, but I hope to remember that if I do.
And I'll likely remove the InitializeComponent.

Hi All,
I have a panel in a windows form(C# .Net 3.5) and this panel contains a varying number of usercontrols.
When there are more controls than visible in the panel I get the vertical scroll bar as desired.
My issue is that when scrolling and the controls are redrawn there is a noticible delay and causes a very unsightly display.
Does anybody have an ideas for solving this issue?
I have tried setting the smallchange and largechange values for the vertical scroll and this seems to be a solution, the only problem is that it only seems to apply when the up/down arrow buttons are clicked and NOT when I click and drag the scroll bar.
If anyone knows of a way to apply this small change value for dragging the scrollbar, I think this will be a suitable approach to take.
Thanks in advance
