This article should have everything you need about doing UI for your Service. A Service is by definition, a program without any UI... so it's tricky to go out of that box.

Hai all I have a problem related to changing the color of text in a rich text box.What I want to do is lets say I have 10 lines of text in the rich text box.I want to change the color (highlight) the color of text from line no 3 to 7.
Pls help.

Selecting the text you want colored, then setting myRTB.SelectionColor should do it.

|

Thanks dear
But the problem is how to select the text.
Ex: I want to display the text like this
for (int i=0; i<10; i++) {
console.WriteLine("Hello world\n");
console.WriteLine("I'm here\n");
}
and I want to color the for statement only.How can I
select the text releted to for statement without statements
inside the for loop.
Plaese help.

hi ...
i exactly can not understand what do you want ...
but for select a text in rich text box and change it's color you can write follow code ...
richTextBox.Text = "test";
richTextBox.Select(2, 2);
richTextBox.SelectionColor = Color.Blue;
|

Hi,
the easiest way is to color the text while adding it to the RTB:
int start=rtb.SelectionStart;
rtb.Add("some text");
int end=rtb.SelectionStart;
rtb.Select(start, end-start);
rtb.SelectionColor=color;
If that is not possible, you must somehow parse the existing text to find
the piece you want colored (e.g. by locating/counting the newlines).

Thank alot for u're help.
But the problem is not solved totally.
The number of characters which change the color is not static for everytime.
It changes time to time.
So can U pls tell me how to color the text from (2 , to the end of the text)
Thanks again dear.

I created an installer project for my C# windows forms app, but it won't overwrite previous versions of the program. The users have to go to their Add/Remove Programs, and uninstall it there, then the new installer will run. I can't find anything about this on Google or in the MSDN. I found reference to a property of OverwritePreviousVersion, but I can't find it in my project anywhere? I've looked through all the properties windows of the application, and of the installer project...
Where do I set this option? I just need it to overwrite the EXE file really... the rest of the stuff can stay... well I'd need to update the shortcuts in the programs menu too I think...

So you just need to overwrite the previous installed versions while installing ?
In that case, just check the properties of the installer project. In the property window, you will find an attribute - 'RemovePreviousVersions'. Set it to "true"(sorry for previous mistake, just set it to true) and i hope it will work.
btw, thanks for your reply to my post.

There is no such thing on my project. That is what I'm saying... I could send screen shots... I have no idea what I'm looking at. I've read the articles that talk about that property, but I can't find it on any of the screens in my Visual Studio. I know it sounds stupid, but it's just not there?!
|

So you are in a strange situation. This option may vary from version to version. I am not sure. I use visual studio 2005. I don't know about other versions..
One more thing, i know you have already checked everywhere for this option. So it's silly to say it again. But still, just to make sure, there are 2 property pages. One if you right click on the SetUp project and click on property. Then you'll see a property page but you can't find it there. But if you just select the setup project, then in the property tab, you should find it. But i know, you must have checked it and can't find it. So I don't know what can be the solution. Hope that, someone else can help you.
Regards
Chayan

Hehe... that's just me. I'm a real bitch online sometimes but I'm actually a friendly and generous person - I'll buy coffee for anyone, maybe even dinner. In my world, I don't meet people in person too often, so it's a nice treat when I get to do that.

I have developed a .Net application. But sometimes it faces some problem during uninstall. For example, if i manually delete the folders, without uninstalling it, i can not re-install it. Then i have to manually delete entries from registry by searching.
I thought that i will delete registry entries automatically with a program and with the some help from the members of this forum, i developed it. Now i am facing 2 main problems-
1. Sometimes, even after deleting all the entries from registry(except those legacy, that can not be deleted), still i can not reinstall my application. It's quite strange. It has no registry entries(except few that can not be deleted) and nothing in C drive. But still when i try to install it again, it says - "Previous version still exists". Can anyone tell me, how can it be existing when i deleted every thing from my PC and registry ?
2. While my program deletes entries from registry, it also deletes some other entries that should not be deleted and makes my system unstable. Is there any specification that, i need to delete only these keys and values. I saw in few software specification, they say to delete only from "LocalMachine\Software\" and 1 or 2 other place.
Sorry for so long message. But i am really confused and need to solve this problem. CodeProject has always been the best source of help for me. Hope i will get some help this time too.
thanks

That's one reason I'm using .Net settings and staying away from the registry.

Sounds like you aren't being accurate with your registry key names. Sorry I can't help more, but if you're just saving preferences or data, the new type of settings file would work well.
