Hi!
Thanks for reply. Yes i am using a thread, but i dont think that thread is blocking the UI thread because i did not made any change in thread part, it is same as before.
Stil i have checked by setting breakpoint in form's constructor, as you suggested, but no clue! no error or exception and every thing went normally..
is it possible that solution file of my project is somehow corrupted?

You could also try setting a breakpoint for the background thread. My bet is it's somehow blocking the UI from drawing.
Most helpful would be to post your code here.

Hi!
Thanks for reply, i have done all work again since last backup and now my project is running perfectly.
I still dont know what was the fault in previous code but i can not afford to figure out the problem due to time constraint...
It was very kind of you to help me. Thank you very much for all this help, i will be looking forward to get more help from you in future.
Regards,

What sort of project is it ? If you set breakpoints, is it running properly ?

Christian Graus!
Thank you for reply, it is a project related to mobile to PC communication. i am using GsmComm library for SMS and Phonebook managment.
It does not show any error or output even if i set break point, project is compiled and status bar shows "Ready" message, but no output is showed.
one more thing! i am also using thread, and i am starting it when startup page loads, previously it was also working perfectly.
Please suggest me what i am missing and what is the reason of this strange behaviour.
Thanks,
Regards,
Affan Ahmad Toor

So where do you expect to see output ? The program is running fine, right, just no output ?

Hi!
Thanks for reply, the output must be displayed after program is compled successfully, just like normally happens.
yes you are rite, program is running fine but no output is generated. did i do something wrong? what is the reason behind this?

If this has already been addressed, just point me in the right direction, please.
I'm trying to make an automatic wallpaper changer (using that user32.dll api that everyone uses, although there are differences among the parameters they choose). What I've done works fine on a PC at work, but it won't work on my Inspiron e1505. I understand it not wanting to display anything but a bitmap, but it didn't even want to display bitmaps on the laptop. Does it have to do with my Inspiron's odd-sized display or something (it's wider than normal displays)? Any ideas?

Can you post your code? We're otherwise in the dark.

I guess the modifications I did to it (while using a work PC... yeah, I know, but I wasn't on the clock) did the trick. Now it works just fine. I was saving images using myBitmap.Save(string filename) when I should have been using myBitmap.Save(string filename, ImageFormat.Bmp). I don't know why that would make a difference, but it did. It still doesn't answer the question of why it wasn't displaying images that were originally bitmaps, but, hey, it works now. Thanks anyway!

hi
so my problem is already explained in the subject, i can't seem to be able to embed an icon in my application and then specify it as a shortcut icon for example for the user's desktop.
in fact the only way i found, to choose an icon for the shortcut is to add an .ico file to the main project but this is not good at all because i don't want users to be able to see a separate .ico file in my program insatllation folder.
i guess there's a trick to do it but i didn't find any help on that 
thx in advance

no one knows how to do that !?

Hi,
I have a dictionary of Terrain objects in a game I'm working on. Here's the class that holds a single Terrain (I didn't include the properties for brevity, but they map directly to the fields):
<code>
public cass Terrain
{
private string name;
private string description;
private List<string> tiles;
private bool blocks = false;
public Terrain ()
{
this.tiles = new List<string> ();
}
}
</code>
Another quick question: would that class be a good candidate for a struct?
I have another class TerrainManager that has a Dictionary<string,Terrain> of these.
I did have code like this to create a terrain and add it to the TerrainManager:
<code>
Terrain terrain = new Terrain ()
terrain.Name = "Grass";
terrain.Description = "The green stuff.";
terrain.Tiles.Add ("grass");
terrains.Add ("grass", terrain);
</code>
That'd be fine if there were going to be just a few, but there will likely be hundreds. So I decided this might be a good excuse to learn a bit about XML. Also this way I don't have to recompile to make a change. Here's a sample of the XML format I decided upon:
<terrains>
<terrain key="grass">
<name>Grass</name>
<description>The green stuff.</description>
<tile>grass</tile>
</terrain>
<terrain key="tree">
<name>Tree</name>
<description>They're big.</description>
<tile>grass</tile>
<tile>tree</tile>
<blocks>true</blocks>
</terrain>
</terrains>
As you can see the <blocks> element is optional and there may be one or more <tile> elements. The key attribute in the <terrain> element is the key used in the dictionary.
I got it to work using XmlTextReader. So I guess I should be happy, but I'm not, because I'm not sure it'll handle all situations gracefully and the code is a bit hard to understand after a day after writing it.
This seems like a simple thing to do. I've read about Serializable objects and thought this might help me, but those tutorials only focus on writing XML from the objects, but I don't need to write XML. I only need to read it in once the program starts and fill the Dictionary<TKey,TValue> in my TerrainManager.
I just want to do this in the simplest way possible. I'm sorry if this post was long it's my first post here. Also I'd be happy to post the code I'm currently using the load the Xml. Thanks everybody, I've enjoyed reading the articles here since starting my journey in C# and .NET.
Also I should mention I'm using Mono on Linux, but I don't think that should matter too much.

Hi Mark.
I think the simplest way to do this would be to use XmlSerializer [^]class. Using this class, you just mark your class with the [Serializable] attribute, then when you want to save your object:
XmlSerializer serializer = new XmlSerializer(typeof(Terrain));
serializer.Serialize(someFileStream, myTerrainInstance);
And when you want to load a saved terrain object:
FileStream terrainFile = ...;
Terrain myTerrainInstaince = (Terrain)serializer.Deserialize(terrainFile);

I'm also a great fan of the XmlSerializer but according to a discussion I recently had in the XML forum it does not support the IDictionary interface. Therefore instances of the Dictionary though marked as Serializable cannot be used with the XmlSerializer.

You're right, however, there are workarounds[^].

Thanks Juda, I'll give that a try. I think this is exactly what I'm looking for.

Hi all,
i'm working on CheckedListBox, where in which i am using itemCheck event To capture the checked and unchecked values of checkboxes of CheckedListBox,
But here if Am loading some values
|
|
|
|
|
The common thing to do is to set a flag that tells you to ignore the event, within the event itself. If it's on page load tho, you could just hook up the event handler AFTER setting your values.

ya i've taken a flag, saying for the first time[when count is zero] i have restricted my itemCheck event code,
but its not working
int count=0;
if (count != 0)
{
if (e.NewValue == CheckState.Unchecked)
{
lstChcked.Items.Remove(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
else if (e.NewValue == CheckState.Checked)
{
//ChklbxAdd= Convert.ToString(chklstMultipleMdfyTbl.CheckedItems.Count);
// string[] ChklbxFill = new string[chklstMultipleMdfyTbl.CheckedItems.Count];
lstChcked.Items.Add(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
}
else
{
MessageBox.Show("try to restrict this event");
}
}
I DIDN't Understand ur last line,
***you could just hook up the event handler AFTER setting your values.**

It's the same thing I'm telling you over and over again.
BTW, your count flag cannot work since you obviously defined it inside the event handler, so it will always have the same value (0) when execution reaches the if statement. The flag has to be an instance field that preserves its value between subsequent executions of the event handler. Furthermore, it would be sufficient to use a boolean instead of an int.

Thnx alot, and i am done with it,
ya i've used bool and used in pageload event.
at last,1 morre,
do u know any alternate method, to deselect all the checked values of Checkedlistbox.
for (int i = 0; i < CHECKEDLISTBOX1.Items.Count; ++i)
{
CHECKEDLISTBOX.SetItemChecked(i, false);
}
if i use this, the total days work is vanishing--i mean the rest of the code that u've helped me is not working,
anyway thnx alot for ur help,

In Visual Studio, add a Setup project. Click on the setup project's file system editor. Right-click, add special folder-> users start menu. There, add a shortcut to the uninstaller.
