Using C# in a winform, I'm creating a file backup program that uses a treeview/listview pair, just like Windows Explorer, only exception is that all entries have checkboxes for selection... you make your selections and then save a backup file (in XML) containing a record of all dirs/files for that job. Works fine.
In order to edit a saved job, the treeview/listview pair must be "re-hydrated", so that all selections for a given job are restored and the user can view and make changes.
I know you can programmatically check/uncheck items, but I'd like to make the selections by sending mouse click messages, just as if I were making the selections for the first time with a mouse... can't use the "node.Check = true" method because it conflicts with my job creation logic.
Is it possible to send mouse click messages programmatically...??? How is it done...?
thanks very much.

you can Invoke the tree's onmouseclick event with that when you fill the tree event object fill the node you want so as if it clicks on that item.

thanks for the reply... can you give me more info or an example of how I can send a mouseclick message to the treeview entry...???
thanks...

Ok Here is the code  what I tried !!!
you can compile and run under shell by
> csc Form1.cs
> Form1
you can derive the TreeView Class and make protected method callable via making public and calling protected method.
Hope this helps or gives hints to your stuff !!!

Please check this code first:
Console.Write("{0}-{0}","2");
I want it to write "2-{0}" not "2-2". How can I do this?
|
|
|
|

I don't know how to escape {0}, but there's another way to do what you need:
string value = "2";
Console.Write(value + "-{0}");

try \{
that's the escape sequence char.

Well, that doesn't work too, I don't really know the escape character for this but you could use the following workaround
Console.Write("{0}-{1}", 2, "{0}");
that will result:
2-{0}

hey I found it, just use {{ and }}
Console.Write("{0}-{{0}}",2);

Hi:
I'm working on a custom control that inherits System.Windows.Forms.Control. What I need the PropertyGrid control do is to hide most of the inherited properties of my custom control. There is a property BrowsableAttributes that is probably meant to do the job but I don't have the slightest idea how this is done! Is it possible for the PropertyGrid to show only the properties I specify?
10x,
Kaloyan

Using the attribute "[Browsable(false)]" should do the trick.
As an example ...
[Browsable(false)]
public string MyStringProp
{
get {....}
set {....}
}
would prevent the property grid from displaying the properity. Setting it to true then would allow the grid to display the properity.
Hey don't worry, I can handle it. I took something. I can see things no one else can see. Why are you dressed like that?

This, however, does not solve my situation... My control inherits around 30 properties from Control which I do not need. So the problem is that I want the PropertyGrid to display only those few that are specific to my control but not inherited from Control. If I use the approach you propose I'll have to add the Browsable(false) attribute to all inherited properties. And this takes a lot of time. The PropertyGrid, however, has that property: PropertyGrid.BrowsableAttributes (the last letter is the difference), which is meant to enable the grid to display only those prperties you want to display. That is what I'm asking and trying to solve in the same time.
Thanks for the response anyway...
Kaloyan
p.s. I fixed this one It turned out that PropertyGrid.BrowsableAttributes must be set to the attributes the properties I want to display have.(confusing, isn't it? )

I'd like to access the members of an event, such as the KeyDown event of a TextBox. Here's an example:
int handlerCount = textBox.KeyDown.GetInvocationList().Length;
This would tell me how many handlers are attached to this event. But the compiler doesn't like it, and gives me this error:
CS0079: The event 'System.Windows.Forms.Control.KeyDown' can only appear on the left hand side of += or -=
What's going on? How can I accomplish what I need?
Thanks,
Alvaro

check Control's event property
for example
this.Events
and it has a AddHandler and getting active handlers ..

I am getting the following exception:
"System.ExecutionEngineException In System.Windows.Forms.Dll"
... and it is occuring when the code is just about to exit the Static void Main block:
[STAThread]<br />
static void Main() <br />
{<br />
Application.Run(new Form1());<br />
}
Has anyone any idea of what could be causing this?
Cheers

I would check the destructor of Form1 or one of its object's dtors. A stack trace would be of great help.
|
|
|
|
|
do you have some kind of Active X or image you are using ?
try to trace the constructor
put a break point in Form1's ctor and try debuging from there
u will be doing F11 not the F10 which skips method debuging.
and step by step you will know exact where it fails.

I don't have any controls on the form at all.
What I do have in the form object is 4 objects instantiated from very similar classes in which I read data from btrieve table files destroy the data read and then it appears that when the 4th object has finished the form object has been GC'ed. I haven't put any destructors in for these objects and beleive this is the problem, as if I only instantiate one or two of these classes I don't lose the form object!

ExecutionEngineException is a kinda equivalent to the old Dr. Watson for Windows. If something that mscorlib or mscoree.dll (the .NET CLR) could not handle, it would throw this exception.
Any misconfigured or mailfunctioning COM components that you are using, might cause your RunTime to fail with this exception.

But unfortunatly the code is massive and my C# skills arent good enough to break it down to find what I need
