Hi. I created winform application.
And There is a empty tabcontrol. When i click menuitem to add tabpage,
i create tabpage and add tabpage to tabcontrol.
It is simple.^^
But, What i want to do is to hadle tabpage focus.
When i press mouse right button on a tabpage,the tabpage must have focus and
show the context menu. when i clicked context menu to close tabpage,that tabpage must be closed.
I don't know how to get the tabpage reference,when i press a right mouse button. Would you tell me the way to solve this problem?
As soon as possibe,i hope you write sample codes.
Help me,please.

Hi,
A few seconds past I asked to access a toolbar with
shortcuts.
Now I want also find a solution for followin problem :
My Form consists of a panel, in that panel I have other
panels (a panel for the header, for the footer and one for
the body). These subpanels have some controls.
Now, I also want to access the subpanel (ex. the
footerpanel) with a shortcut key and then use the arrow-
keys too scroll in the controls of that panel.
Is there somebody who have a hint?
Thanks in advance,
Vic

Hi,
I have a windows form with a toolbar and some other
controls.
Normally you access the toolbar-members with the mouse.
But how can you access the toolbar with a shortcut (lets
say for example Alt-T). So, you are positioned on the
first member, And too access the other members you have
(you could) to use the arrow-keys.
I need this things for the case that the mouse is broken.
Thanks,
Vic

I created a custom control derived from Control but it doesn't seem to have the default focus behaviour (i.e. mouse click inside the control gives it focus). If I add a handler for OnGotFocus it never gets called.
How can I make it respond to focus events?

Hi guys, i'm sorry for this post since it's clear i still haven't grasped the big picture of how this works yet, so please forgive my ignorance...i'm still very new to c#.
Can someone explain to me how i can use this code to connect to a database and display records? i'm not worried about the db connectivity, since i have that part working, but i am having a problem understanding how to use this code in sections...
for instance, i want to open a dbconnection, then run a sql query based on user input, then close the connection. The only way i know how to do this is to create ONE method that opens the database, executes the query, then closes it again. I'd rather do it in sections like what i have, but maybe that it isn't the best programming...any input on how i can structure this would be helpful.
thanks.
namespace CreateConnection<br />
{<br />
public class dbcon<br />
{<br />
String _dbString;<br />
<br />
public dbcon(String _dbString)<br />
{<br />
OdbcConnection dbConnect = new OdbcConnection(_dbString);<br />
}<br />
<br />
public void dbopen()<br />
{<br />
dbConnect.Open();<br />
}<br />
<br />
public void dbquery(String _dbquery)<br />
{<br />
String output = "";<br />
<br />
OdbcCommand cmd = new OdbcCommand("",dbConnect);<br />
cmd.CommandText = _dbquery;<br />
OdbcDataReader dr = cmd.ExecuteReader();<br />
<br />
while(dr.Read())<br />
{<br />
for(int i=0;i<dr.FieldCount;i++)<br />
{<br />
output = output + dr.GetValue(i) + ",";<br />
}<br />
output = output + "\r";<br />
}<br />
<br />
dr.Close();<br />
}<br />
<br />
public void dbclose()<br />
{<br />
dbConnect.Close();<br />
}<br />
}<br />
}

What's the difference between LocationChanged and Move events for Controls?
The documentation isn't very clear, but it reads as if LocationChanged is a superset of Move, but it seems that in practice both are called at the same time, except that Move events are fired just before LocationChanged events, perhaps.
It looks like I'll be using LocationChanged, to be safe, but if there are any suggestions otherwise, I'll take 'em!
Thanks,
Arun

      iv been trying to find some reasonable info on how to Bind DataBase Field to Column BackColor Property.
this only binds the data grids main properties back color but i need the individual Column to be bound.
dataGrid1.DataBindings.Add("BackColor",DataSource,"DataSource.Field");
Does what is below have anything that can lead me to it?????
// Use a PropertyDescriptor to create a formatted column.
PropertyDescriptorCollection myPropertyDescriptorCollection = BindingContext
[myDataSet, "Table.Field"].GetItemProperties();
// Create a formatted column using a PropertyDescriptor.
DataGridColumnStyle csField =
new DataGridTextBoxColumn(myPropertyDescriptorCollection["Property"], "c", true);
csField.MappingName = "Property";

Hello Hoang Dung,
I think MSHFlexgrid only works with VB but not 100% positive. Try the following Link and you'll see MSHFlexgrid is listed under VB 6.0.

you can use a flexi grid in C# , just add it to the toolbox :
VB:
<font color="blue">Private</font> <font color="#0000FF">void</font> button6_Click(<font color="blue">Object</font> sender, System.EventArgs e)
{
<font color="blue">For</font> (<font color="#0000FF">int</font> i=0;i<20;i++)
{
axMSFlexGrid1.AddItem("item\t" + i,0);
}
}
hope that helps.
<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
{
<font color="blue">switch</font>(twins)
{
<font color="blue">Case</font> ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
<font color="blue">break</font>;
}
}

How I can show a html page in Windows Form and scale the whole document to a smaller size. It's like when you browse a hard disk and click on html page then you can see a small preview of this page on the bottom-left in Explorer. So the quaestion is - how I can make this 'preview' window in C# ?
|
|
|
|

There probably is a better way, but here's one that almost has to work.
Open a hidden web browser, and load the desired page. Capture the image from that browser's screen, scale it down, and display it where you want it.

Hello again gurus,
When you add a INHERITED Form to your project, you get to a form named "Inheritance Picker". This form is very small in size and the items in the list are so tiny. It's a pain to figure out what to select on my monitor.
If gurus have any ideas how to improve it, I appreciate your tips so much.
Thanks again and have a great day

Hello Gurus,
I could not find where to turn on the Line Number option in C# code editor like we can do in TextPad or JCreator.
Thanks

Hi!
I am writing a kind of spy tool in c#. Now I need to find out what
files are currently used (opened) by a certain process (knowing the
processid).
I know that there is this undocumented windows function
NTQuerySystemInformation, but I hope that there is another solution.
I tried NTQuerySystemInformation, but as I am not an interop-expert
I could not make it work  ...
Is there anyone that solved that problem once, or has a code example
on how to invoke NTQuerySystemInformation in c#?
