hi friends.
All of you have seen that tab in visual studio where solution explorer, toolbox, properties is written and when user move mouse over them, one panel come out where we have some data in treeview. Hope you got the scenario.
Now i too have 2 treeview in my window application.
and i want the same interface which visual studio provide in my application.
is there any inbuilt control provide by framework.
Hope you understand what i want.
Thanks lot friends.

You are looking for a tab control with auto hide and run time docking feature. Unfortunately currently any window control does not provide you similar features.
However there are many third party tab controls which come with these features. You may use google to find them.

Take a look at the Dockpanel Suite[^] on SourceForge. It's quite good. If your application is meant for the average user though (as opposed to the average developer) I would reconsider using these kinds of controls, as they often find the VS way of doing things overly complex.
Standards are great! Everybody should have one!

You will need to install, installshield setup creator software. One you are done with this, you may use install shield to create a setup for it.
You may also check its help file for getting steps to use it.

Hello Sir/Mam,
I want to synchronise 2 images.when I perform operations like zooming ,panning on one image the other should get effected automatically. I have performed this in the following way......
In the mouse wheel event i am performing zooming. and mouse down and mousemove events i am performing panning.I am not using any scroll bars...
The problem is when i'm performing zooming(i.e., when i'm rotating the mouse wheel fastly then the images are not synchronised properly..I should overcome this problem.. pls help me..
Thanks,
rekha.

Well, I'd love to help, but seeing as you didn't post any code, I have no idea what you did wrong.
You should be storing the zoom for both images in one variable, so it's in sync

I assume you realise that this code is auto generated. I kind of meant just the pertinent code that you actually wrote.

actually we have posted every thing,that is why you confused , and you can observe the remaining things
in user control, and form code.
Thank you for your quick response.

I know what you did, I was asking why you couldn't take the time to create a post where I didn't have to read two huge posts looking for the little bits that are pertinent to the problem.

When I coding C# language to connect SQL Server and then. I write stored procedure to insert into table, and I want to show data immediately in datagridview in form and orthers controls.
So that, I want to coding procedure or function with C# to refresh datatabase name.
Who can help me?
If posible I thanks so much.
For example:
I using: Namespace
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;
Function:
Server srv = new Server();
Database db = srv.Databases["Database_name"];
db.Refresh();
Thanks

???, your question isnt proper, however if you wanna add DGV at runtime, then you will need to add it in the form else it wont show up
code to add control in form :
this.Controls.Add(tmpDGV);

Hello
One little thing : my intent was not tho show the DGV but to fill it with a datasource to print it with another control
Anyway the problem is the same : if the DGV is not added to the form, the Datasource has no effect.
Thank you

Hi! I have a data table called maps that had been bind to a list view. I would like to add an event to the list view that is onSelectionChange. Inside this event, when user make a new selection I will display the selected data out into a detail view. Does anyone know how to do this by using listview.SelectedValue? I am building whole thing in wpf and c#. Thanks for your help.
I had try out this code but it always return -1.
DataView view = new DataView(maps);
view.Sort = "mapTitle";
MessageBox.Show(view.Find(mapListView.SelectedValue).ToString());

Hi,
you have to register for event and create method that will handle that event.
Method could look like this:
void mapListView_SelectionChanged(object sender, SelectionChangedEventArgs e)<br />
{<br />
}
and you have to tell mapListView to call your method. you can do it in xaml like this:
<ListView Name="mapListView" SelectionChanged="listView1_SelectionChanged"
or programatically (after mapListView is created and initialized):
this.listView1.SelectionChanged += new SelectionChangedEventHandler(listView1_SelectionChanged);

When I try to perform the math below I get an answer of 0, but the result of the below should be 5.76
Int64 lpTotalNumberOfFreeBytes = 41085476864;
Int64 lpTotalNumberOfBytes = 712212955136;
Int64 strAnswer = ((lpTotalNumberOfFreeBytes / lpTotalNumberOfBytes) * 100);
Does anyone see what I am doing wrong here?
Thanks

hi,
int/int performs an integer division; you should consider one of these fixes:
- use float or double everywhere
- postpone division, hence do 100*int/int instead of int/int*100
(there is an increased risk of overflowing when doing all multiplies before all divides)
The above holds true in most programming languages (C, C++, Java, C#, ...).

You can use float everywhere as Luc adviced you. But if you for some reason need to store lpTotalNumberOfFreeBytes and lpTotalNumberOfBytes as Int64 you can covert their values in division expression like this:
((float)lpTotalNumberOfFreeBytes / (float)lpTotalNumberOfBytes )*100;
However this expression return float value so you need to change type of strAnswer from Int64 to float or convert explicitly convert result to Int64:
Int64 strAnswer = (Int64) (((float)lpTotalNumberOfFreeBytes / (float)lpTotalNumberOfBytes )*100);
But remember if you convert float to Int64 system will cut off everything behind decimal point, so in this particular case result 5.7687068 will be converted to 5.
