Hi All,
Is there a control somewhere that allows you to display HTML text in a text box on a Windows form?
Reason I am asking is that I am currently using a Rich Text control, but we run 2 systems (one a windows system and one a web system) off the same database. The web developer have asked that we change all our rich text boxes to HTML controls so that he can display it on the web.
So in essence I would need something that would be able to read raw HTML code (from a database) and display it on a windows form so that it looks more or less the same as it does on the web.
Hope that makes sense!
Thanks a lot in advance for any replies.

Hi,
the WebBrowser Control shows an HTML page if you call Navigate() or assign a string to DocumentText; by setting some properties you can make it a view-only Control.

we have several documents where we have steps for installtion of a software and they vary for each version released.
Steps may include :
Third party tools to install
Prerequisites
Procedure/way /steps to follow during installation
For each new version there will be some changes in this documentation.
When a person want to install software of particular version (say 2.2) he may go to documentation and follow the steps.
But everytime it is hectic to go for each version documentation and look for changed steps.
So my idea is to develop a web application where i can compare the differences in each version (for example i want to get the steps that differ during installation for version 2.2 and 2.3 )

Not a bad idea, and easily implemented. Assuming the user knows which version he/she is trying to install, you can provide a listbox with all the available versions. When the user selects a version from the list, your application can respond with the correct documentation for the selected version. You can do this in multiple ways.
One would be to rewrite your existing documents into separate instructions for each version, convert them to webpages, and serve up the right version when a selection is made. Another would be to create a single page, and modify its contents based on the selection before returning it to the user. Yet another would be to store each possible step in a database, then select the relevant items to assemble a webpage displaying the proper instructions for each version.
The last would be the most difficult, but it would make it easier later to add new steps for future versions to the database and provide code to assemble it correctly.
I'll be watching for the article here when you finish the project.

I'm trying to develop a windows application where i can get connected to remote server and look for process state.
We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.
So our aim is to develop a windows application where i can get connected to servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)

Its simple its like File System if you have access to your Remote Servers then you can easily do.

Hi Guys,
I intend to develop a desktop application and my targeted audience are small business companies, they usually have a P3/P4 system with 256mb of ram running winxp and might not have good internet connection. I want to know the best application development tool.
I thought that I should use LINQ TO SQL, so i would be facilitated with new features of .net, but requirement of this feature is .net3.5 installed on client machine which makes deployment of the application a big headache.
My requirements are RAD of GUI and business logic with very easy deployment, like a DELPHI applicaiton.
I am using a DELPHI application and its installation file is of few MBs and installed with in few mins without much pain, on the contrary .net deployment taking too much time and irritates client.

Why not use Delphi? There's nothing wrong with it, and it has a strong following. A bigger hammer is not always a good solution, but it sounds as if you're trying to find a reason to use a big hammer when there's no reason for it.

Other than your desire to work in .Net, is there any business case for using a tool that will hog resources and possibly annoy your customer?

Well reason behind going for .net is that, I am a .net developer, and for DELPHI there is learning curve, and I am not sure its worth learning DELPHI?

I haven't seen much Delphi-related work lately. Take a look at some Delphi-code and try to estimate whether it's worth it for you. Alternatively, you might want to consider installing a smaller .NET runtime, something like Mono

I have Windows Form which is implemented as per singleton pattern and having TableLayoutPanel as container on it for other controls to be placed on it and it is generating an anonymous problem regarding controls movement in which they change their position when set as mdiChildForm of a mdiParent Form. In this scenario if a windows Form is not being implemented by singleton pattern then it is working fine and if not then the Controls like lable and others are changing their location when the form appear on screen inside mdiparent second time by the user. The further detail regarding this problem is described below.
There are two Forms named as UI-1 and UI-2 and one Is the MDIParent Form named as MainForm.
Form UI-1 has the singleton pattern implementation and can only be initialized by GetInstance() method as you can see from code given below.
The code In the UI-1 Form:
public partial class UI1 : Form
{
private static UI1 frm;
public static UI1 GetInstance()
{
if (frm == null)
{
frm = new UI1();
}
return frm;
}
private UI1()
{
InitializeComponent();
}
public void ShowLabelCoordinates()
{
MessageBox.Show("Location: " + this.label1.Location.ToString() + " Position: "+
this.label1.PointToScreen(this.label1.Location).ToString());
}
}
Form UI-2 is with its usual constructor and can be initialized directly from it as you can see from code given below.
public partial class UI2 : Form
{
public UI2()
{
InitializeComponent();
}
}
The code in the main Form which is actually a mdi Parent Form.
UI1 frm = UI1.GetInstance();
frm.MdiParent = this;
frm.Show();
frm.Focus();
frm.ShowLabelCoordinates();
UI2 frm = new UI2();
frm.MdiParent = this;
frm.Show();
frm.Focus();
Sample Application has been attached at this link

Any immediate assistance will be highly appreciated.

Hi peeps!
I've got a Windows Forms application that opens another Windows Form as a dialog (IE ShowDialog).
When the dialog is closed I call Dispose on the object, set it to null, and then call GC.Collect().
However when looking at the memory usage in the Windows Task Manager, the memory usage never goes back down to what it started at initially.
I know that you can't determine when garbage collection is done, but I thought that was the purpose of the GC.Collect() method.
For example it starts off at 6,360k; if I open and close the dialog say 10 times, the memory usage goes up to 7,104k
I leave it running in minimized state for half an hour and the memory usage is 7,080k.
(Interestingly if I maximise it, then memory usage goes up by varying amounts, and stays there.
Minimize then maximize and it does the same again. Keep doing this and it stops increasing after about 100k of extra memory increase, but the memory never goes down to what it was before I did the 'jiggle').
I've run FXCop on the assembly to see if I hadn't implemented any Dispose functionality correctly, but it didn't highlight anything.
There's nothing in the entire application that is accessing files or databases - just what I would call standard .net stuff.
Am I overlooking something, am I worried too much, or am I just being stupid?
I've done various searching and reading on google, but still seeing this effect.

your multiple choices aren't mutually exclusive, but I trust you're mostly worrying too much. What's another megabyte?
FYI:
- it all depends on where you look. Task Manager isn't a good place. My big apps typically show both clock time and Environment.WorkingSet in a status bar, updating at 1 Hz.
- a .NET app normally does not return any free memory to Windows; it does when getting minimized though.
- it may depend on Windows version and overall memory usage situation. More recent Windows (Vista, 7) tend to keep memory full of potentially useful data (similar to your app caching something with WeakReferences)
- AFAIK GC.Collect() isn't blocking, it just initiates (or suggests?) a collection. And one of those probably is insufficient to free all dead memory, as there are generations and a finalizer queue. If you must force GC, try a 3-iteration loop with Collect+wait100msec.
- You are aware calling GC.Collect in general isn't a good idea, it messes up the nice Microsoft machinery, well that is what they claim anyway.

I wasn't aware of that, so will take it out.
Trouble with reading stuff on the internet is that a lot of what you read can be contradictory!
Another thing I have found is that it's not so easy to see tell what the developer should be disposing of in the safe way.
But I guess that's down to experience.
Anyway, thanks for the info.

you're welcome.
see, it pays off not to fish for a vague answer...
this is what I wrote in my animation article: if you need to create some objects (Fonts, Pens, Brushes, ...) either create them inside the Paint handler and don't forget to call Dispose() on them (one must call dispose on instances of a class that offers such method), or better yet create them only once and keep them alive in class members, this avoids creating a lot of new objects, followed by disposing and collecting them.

Big mistake. Task Manager show you how much memory the .NET CLR has reserved for you application, not how much it's actually using. Think of the .NET CLR as a virtual machine, a kin to Java. You're seeing the memory that is allocated for the vm, not for what's running inside it.
The .NET CLR maintains a managed memory heap. This is memory that is allocated by Windows and handed to the .NET CLR. The CLR take that memory and allocates everything out of this heap. When your app is done using an object (it goes out of scope), that memory is returned to the managed heap, NOT to Windows. So, according to Task Manager, your app will be "using" 20-30MB of RAM, when it's really only using 10.
Instead of using Task Manager, use Performance Monitor (Start/Run -> Perfmon.msc). You'll find all kind of .NET memory counters you can use to see what your app is really using.

No, it doesn't. GC.Collect only suggests that the Garbage Collector be run. It's really a bad idea to do this, unless you really understand why your doing it, how the GC works, and understand the side-effects of running it.
The GC is self-tuning. It watches how your app allocates and frees memory and tunes itself so it doesn't interfere with your app and can keep memory (free and used) organized with future performance in mind, such as allocating future object faster.

Ok, I will do that.
I guess I'll go and do some more background reading on how the CLR uses memory - I don't think I understnd it properly enough.
Thanks again, it's much appreciated.

I need to know whether it is possible to add a datagridview inside a datagridview combobox control.
For reference i am posting a image example which you will get here.If anybody can tell me where I can get the information please let me know.
