Windows Forms

2 points.

1. This is the Windows Forms forum, not the ASP.NET forum. Please don't post into inappropriate forums.
2. You're trying to show a messagebox in code that runs on the server, where normally there won't be a logged in user. Don't do it.

You are best to ask asp.net related questions in the asp.net forum.

Step one - rephrase your question so it makes sense. Do you want to launch a second form ? Pass data between forms ? In any case, it sounds like the logical answer to this question will be to tell you to buy a basic book and work through it so you have a rudimentary understanding of the framework you're using.

How to show image in ListView Second Column **** urgent

27-Nov-07 0:07

OK, it's as I thought. Programming is more than dragging buttons onto a form. You create an instance of the new form in the click event and you show it. If you can't understand what I just said, that just proves you need to buy a book.

Hello,

i am working on C# 2.0 winforms.

I have a ListView, in this there are 5 columns, in second column an icon need to be displayed.

my code as follows...

listView1.Columns.Add("");<br />
listView1.Columns.Add("");<br />
listView1.Columns.Add("two");<br />
listView1.Columns.Add("three");<br />
listView1.Columns.Add("one");<br />
listView1.Columns.Add("two");<br />
listView1.Columns.Add("three");<br />
<br />
listView1.FullRowSelect = true;<br />
listView1.GridLines = true;<br />
listView1.View = View.Details;<br />
listView1.SmallImageList = imageList1; //imageList1 is having 1 icon.<br />
<br />
for (int I = 0; I <= 10; I++)<br />
{<br />
   ListViewItem item = new ListViewItem("");<br />
   item.SubItems.Add("");<br />
   item.SubItems.Add("aaa"); <br />
   item.SubItems.Add("bbb");<br />
   item.SubItems.Add("cccc"); <br />
   item.ImageIndex = 0; //this code showing image in first column<br />
   listView1.Items.Add(item);<br />
}

my problem is... item.ImageIndex = 0; is showing icon in only first column. i have to show icon in second column.

how to to do?
any sounds will be greatly appriciated.

Well, I'm sincerely delighted for you. Just this morning, I was saying to my wife - "if only I had two forms, one of which has a button 'Add' on it which could be pressed and the value appears on form 1." And ye verily, she did say to me "Get a life you sad idiot".

I assume that there's a question lurking about in there somewhere. I'm also going to go out on a limb and assume that the question is "How do I get a value from form2 to appear on form2?" Try reading this[^] article. (Sidenote - I hope that you use better names for your forms than this).

I assume one of those 'form2' instances should be 'form1'. I didn't even get that was the question, I assumed he had a bizarre bug that no-one could solve without seeing the code.

Retaining Focus in owned Forms

Hi ,

I`ve just hit an interesting roadblock in my app & would really appreciate any help / feedback. The "bug" can be replicated easily.

Basically, I have 2 forms running as 2 different processes , say Form X & Form Y.
Their properties are :
Form X : ShowinTaskbar = true , FixedToolWindow , Maximized.
Form Y : Showintaskbar = false , Borderstyle.None , Normal

We have methods on Form Y that can be invoked via Remoting to do Show(owner) , usually Form X ends up being the owner here. I`ve impleneted the IWin32Window interface and initialise it with my Form X`s handle (obtained via FindWindow)

The issue is that Form Y can NEVER retain focus (say when u click on a text box in it) and focus always gets transferred to the owner Form X. I`m not really setting an Owner / Owned relationship between them formally, say , via AddOwnedForms in Form X or Form.Owner = FormX since i guess this doesnt work across processes.

If we change the ShowInTaskbar property of Form X to false , or Form Y to true then there is no problem with the Focus.

Can someone please suggest where i`m going wrong or if theres any other action i need to do ? I dont really understand how the ShowinTaskbar property is affecting the focus mechanism , or whether this is how windows itself works.

So far i`ve tried doing a Activate() , Focus() & BringtoFront() in Form Y but it doesnt work.

SetParent isnt an option since it couples together their lifetimes i.e. if child crashes parent also crashes.

Thanks in advance

As far as i understand your problem that is when you call formY then it shows behind the formX or lost focus when you click on its controls
if yes then you can solve it by 3 ways
1.use ShowDialog()
2. before calling FormY then set its TopMost property to true (perhaps it work)
3. write this.Focus() in Deactivate event of FormY

Hi xmen_xwk ,

many thanks 4 ur reply. Right now Form Y is being shown , thats not an issue.
Actually what i`m trying todo here is make a set of Forms work together and we can interact with any form at any time even though they are in separate exe`s.
For eg: , do like minimize together , toggle between various owned forms(1 owner form is controlling a set of other owned form`s being shown or hidden),display them in a predefined part of the screen etc..

* showdialog() is a good idea but if i do it then i must close the Form Y and only then i can interact with Form X right ? so the blocking call causes problems
* Plus doing this.focus() in deactivate means i can never transfer control away from Form Y Smile | :)

* All the forms are non-topmost bcoz then they will then be minimized and restored together. Would u suggest changing the TopMost value on various events like OnMinimize or LostFocus ?
that sounds promising.will try that

Theres a "hack" i`ve tried as below with some dummy form A :

Form A (grand-owner) : Form X (Owner) : Form Y (Owned)
All are topmost=false , Showintaskbar = true only for Form X and is false for others.
This helps solve the Keyboard focus problem , but i cant really put a "dummy form" into the actual production system code.

If its ok with u I could also mail a copy of the sample project for this issue.

buddy your problem is strange for me because i still not understood what is the problem and what are you trying to do....
if you explain exact what you want (if you like) then it will be better to understand.

i just understood that you want to interact in all 3 forms....
