Hi,
a keyboard key has autorepeat, so it will generate multiple KeyDown and KeyPressed
events when you hold the key down. A mouse button does not.
If you need a repeat for the mouse button (or a faster repeat for a keyboard key)
you can use a Forms.Timer that runs all the time, and checks whether the ccndition
is satisfied (either key is down or mouse button is down).
For "key is down", set a variable lastKey to the key that is down in KeyDown,
and set it to Keys.None in KeyUp; for "mouse is down" use Control.MouseButtons
(there also is Control.ModifierKeys for CTRL/ALT/SHIFT).

Mouse down is a single thread event -TRUE
But you can use multi threading in it.
start a thread on mouse down and
stop it on mouse up

you can do it using two events:
1. when mouse down
2. when mouse get off the button range
in step #1, you know that the mouse is down. in step #2 you know that the mouse left the button, then you can stop the thread you started in the first event!

Wondering if anyone can point me in the right direction, as a starting point, in building a frame accurate High Definition Video player i.e. must be able to control the HDV at the frame level. Have been spending time looking into various SDK's like WMV HD, DirectShow and DirextX with no clear concensus on the correct direction. Any pointers would be apprciated. Thanks

Hello ,
I have one class in C# which I need to post into messagequeue as an message.
I am using XmlMessageFormatter. Problem is the message posted in to message queue is in Ascii format not unicode. I need it to get posted in unicode format.
Can anyone help it out.
Though attributed my class as [StructLayout(LayoutKind.Sequential , CharSet=CharSet.Unicode)] it didn't work out.
Please suggest me.
thanks,

Hello,
Create two ArrayList's.
Iterate over the Items, split the item with ',' char.
Add the splitted results to the ArrayList's!
All the best,
Martin

Hi,
I have a small c# console program which is deployed on a network drive in over 100 sites. However when I update the code and redeploy the executable I have to manually phone each user and set the .net framework security on each machine. Is there an easy way around this. Can I write some code top handle this?
Thanks
John

Hello frnds,
i want to read the mobile no. entered in txtbox digit by digit....

Use the TextChanged event.
Standards are great! Everybody should have one!
|
|
|
|
|
try this :
for(int i=0;i<textBox1.Text.Length-1; i++)
{
MessageBox.Show(textBox1.Text[i].ToString());
}
When you get mad...THINK twice that the only advice

I think you could use the textBox1_KeyDown(object sender, KeyEventArgs e) event for your textbox...here you have e.KeyCode and other more properties that can help you very much.
Just call me Valy...

(This application is a Pocket PC application)
I have the following problem:
I create a dataset in code and add some rows to it. Then i show these rows using a datagrid.
<br />
<br />
DataSet ds = new DataSet("dataset");<br />
DataTable mytable = new DataTable("vizite");<br />
DataRow dr1, dr2;<br />
<br />
DataColumn dc = new DataColumn("bifat1");<br />
dc.Caption = "bifat1";<br />
dc.DataType = System.Type.GetType("System.Boolean");<br />
<br />
DataColumn dc2 = new DataColumn("bifat2");<br />
dc.Caption = "bifat2";<br />
dc.DataType = System.Type.GetType("System.Boolean");<br />
<br />
mytable.Columns.Add(dc);<br />
mytable.Columns.Add(dc2);<br />
<br />
<br />
dr1 = mytable.NewRow();<br />
dr1["bifat1"] = true;<br />
dr1["bifat2"] = false;<br />
mytable.Rows.Add(dr1);<br />
<br />
dr2 = mytable.NewRow();<br />
dr2["bifat1"] = true;<br />
dr2["bifat2"] = false;<br />
mytable.Rows.Add(dr2);<br />
<br />
ds.Tables.Add(mytable);<br />
<br />
dataGrid1.DataSource = ds.Tables["vizite"];<br />
<br />
This part works the way it should it shows:
+----------+
|True|False|
+----+-----+
|True|False|
+----+-----+
After this i want to change in the dataset all "True" values to "Yes" and all "False" values to "No".
This is how i wanted to do it:
<br />
<br />
int i;<br />
<br />
for (i=0;i<ds.Tables["vizite"].Rows.Count;i++)<br />
{<br />
object cell = null;<br />
string cellstr;<br />
<br />
cell = ds.Tables["vizite"].Rows[i].ItemArray[0];<br />
cellstr = System.Convert.ToString(cell);<br />
if (cellstr == "True")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[0] = "yes";<br />
}<br />
if (cellstr == "False")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[0] = "no";<br />
}<br />
<br />
cell = ds.Tables["vizite"].Rows[i].ItemArray[1];<br />
cellstr = System.Convert.ToString(cell);<br />
if (cellstr == "True")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[1] = "yes";<br />
}<br />
if (cellstr == "False")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[1] = "no";<br />
}<br />
<br />
}<br />
The problem is this code is not doing anything...i cant see the changes. The table is still the same

Hello,
What does the debugging tell you?
Is the code were you set a value to the Item excecuted?
If yes, maybe you only need a "Refresh()" or "Invalidate()" of the control.
Apart from that:
Use "else if".
string.Equals
Don't always access an Item over the whole Indexer structure (Row actRow)
All the best,
Martin
P.S.:
Just saw that it is your first post here on the forum.
Your question is detailed and has a good subject statement! (But you should use the "pre" Tag for code snippets)
Got my '5' to say: Wellcome!

The code inside the if is executing i've checked when i debugged the program.
The instructions inside these 'if's are executing as they should
<br />
if (cellstr == "True")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[0] = "yes";<br />
}<br />
if (cellstr == "False")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[0] = "no";<br />
}<br />
<br />
cell = ds.Tables["vizite"].Rows[i].ItemArray[1];<br />
cellstr = System.Convert.ToString(cell);<br />
if (cellstr == "True")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[1] = "yes";<br />
}<br />
if (cellstr == "False")<br />
{<br />
ds.Tables["vizite"].Rows[i].ItemArray[1] = "no";<br />
}<br />
I really don't know what the problem is! 
I've tried with this.refresh and this.update too...well i'll try with invalidate too. though i have a feeling it wont work. 
...
It doesn't.

This doesn't work either. I don't think that i get no changes because i need to make refreshes.. but i don't know what else should i do or what am i doing wrong.
