hi!
i inherit a windows form then added a property named ListControl that is a control type.
if i'll set the value for this property, the list of possible values were already filtered by control type.
what i want is to filter it again by datagrid and listbox. so it's just like having a second level filter. how can i do this?
any ideas or suggestions will be appreciated!
thanks in advance!;)

Hi!
I am looking into how possibly I could enable users re-arrange items in a listbox or listview by dragging an item from one index into the desired index.

Hello,
I am writing two programs, one in c++ and the other in c# and am using windows messaging for communication between them. As of now, the c++ program successfully sends a message to the c# program and the c# program receives it just fine. I need the c# program to send a reply message to the c++ program after it finishes its tasks. I have ran into some problems. First off, here is the code in c# that I am using to define the SendMessage function...
DllImport("user32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public static extern IntPtr SendMessage(IntPtr hwnd, uint Msg, int wParam, int lParam);
I did some research on this dll import and found multiple variations, here is one...
[DllImport("user32.dll")]
public static extern int SendMessage(int hWnd, uint Msg, int wParam, int lParam);
does anyone know the correct variables to used so a c++ program will accept the message.
further more...
I tried both declarations of SendMessage and the c# program still did not send a reply message. Note, I used spyxx.exe to find this out. I saw that the message from the c++ program was received but no reply was sent out by the c# program.
here is how I am sending the reply message in c# program...
Form1.SendMessage( Form1.FindWindow("ConsoleWindowClass", "camController"),
REPLY_PICTURE_READY,
0,
0);
I would greatly appreciate input on this, thanks

Jesse Liberty's Programming C#, on O'Reilly press. $40 new, probably can get used for $30ish. The approach is really one of "ok, so you know the basics of programming in general, here's how you program in C#." Its not C# for dummies, its C# for programmers.

Hi,
I have an XML file which has number of nodes(written using WriteXML() from a dataset)....
It looks like....(small sample)
- <newdataset>
- <schematable>
<columnname>F1
<columnordinal>0
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>General
<columnordinal>1
<columnsize>255
<datatype>System.String
- <schematable>
<columnname>Number
<columnordinal>2
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>Currency
<columnordinal>3
<columnsize>8
<datatype>System.DateTime
........(it continues till end of file).
Here ,i need the node DataType datas(sys.string,sys.double...) alone to fetched and stored in an array for further purpose ...
How to do it?Help me
Thanx...

I think you can read the contents of the nodes only as strings. Once you've read the content of a node, you could try Int32.Parse(), Double.Parse() and so on, and see if what you've read is an int or a double or a string.
HTH. 
Cheers,
Vikram.

I need to read the value(system.string,system.double...) alone from this tag...
This is for checking a condition...
Cud u tell me yaar?
Thanx

Assuming you'll be using DOM style parsing, load the document using XmlDocument[^] and iterate through the nodes, using the Value[^] property to get the actual value.
Something like
XmlDocument doc = new XmlDocument();
doc.LoadXML(strXML);
foreach(XmlNode node in doc.DocumentElement.ChildNodes)
Console.WriteLine(node.Value);
Regards

I had created an MDI application for Touchscreen based dvpt using C# .net.
I have placed 3 panels in the MDI parent. The Top panel, left panel and center panels. The top panel displays the application name. the left panel displays the navigation buttons. The center panel displays the necessary details. Here i need to pop-up some windows to display some details. the pop-up windows are child forms. When i set the parent and pop-up these windows, they hide at the back of the panel and are not visible. If i do not set the mdiparent then they are visible. How can i overcome this problem?
Regards,
Madhu Srinivasan

The centre panel is blocking the child MDI windows. You can either get rid of the centre panel and place your user controls elsewhere, say the toolbar, or set aside an area within the centre panel, maybe another panel, and set this as the parent of the child windows (the child windows would then be normal windows, not MDI children, and set the WindowState to Maximized.
I am leaaving for work now, but if you are still having problems, e-mail me a *small* sample project and I will take a look at it when I get there.

If you only need to reference the main form from the sub-forms, then you could just set the Owner property after it is constructed.
ie from the main form:
NewSubForm form = new NewSubForm();<br />
form.Owner = this;<br />
form.Show();
...in the sub-form:
this.Owner.Text = "New Caption";

I recently found that you can associate a file type with an application through creating file types in a setup project. However, how do you handle loading the file when you double click it? Say to load all of the elements within the file into a dataset and then a sorted list?
Thanks
|
|
|
|
|
All the setup program does is associate the file type with an executable. It usually registers something like
YourApp %1
so that the file you double clicked on will appear as a command line parameter to your app. Assuming it's setup that way, all you have to do is check for the file name in Main and do the required action.

Could you post an example or point me in the right direction?

Would you need to create another static void main with a string as a parameter?
Thanks

Hi,
I've a activex browser control in a form. I've added proxy server support to the control by modifying the proxy server settings in the registry. This works fine before the browser control is created (the browser control is only created after a button on the form is pressed). However, once the initial proxy settings are commited and the browser control is created, the browser control does not respond to any new settings even though the registry shows the correct new settings. The browser control seems to be "stuck" on the old settings. How does IE apply any new settings?
Any suggestions?
Thanks
