A timer and a date/time picker has completely different uses. What is it that you are try to do, really?

b { font-weight: normal; }

Well any component you use will have a 1 sec timer.. you need to refresh your control on 1 second, don't you?

You could just change the text of the label continously in a loop. However:
This would cause the text of the label to flicker a lot.
It also uses all the cpu time it can, causing the computer to run at 100% cpu all the time. This will give you a lot of heat, and render the computer virtually useless for anything else.

b { font-weight: normal; }

You have to change your web.config so the forgot password page is excluded from the forms authenication control.

I am doing a project Mbile Medic.
This project aims to implement a C# based system that helps a doctor tap into his patient database at the hospital via his personal mobile phone and monitor their condition. This helps the doctor monitor his critical patients wherever he may be. The project is implemented by creating the patient database software system for the hospital. The communication module for the software system interfaces a mobile phone (lets call it X) via a serial port or a USB port (depending on the model). The doctor sends an SMS message with the patient ID via his mobile phone to X. The software system collects the message from X and based on the patient ID, queries the database for the patient details, summarizes it, and sends it back to X which then sends the summarized message back to the doctor. The doctor will also be able to send alerts and prescribe medication using this system.
I am using Siemens s35i.
If i send the command to get manufacturer info (AT+CGMI) am getting the response. But if i send the command to receive messages Iam not able to receive messages.. Actually i don know which commands to use. Can u please help me...

I have a matter with Ms.Access. I don't know how to pass the value from one form to another form. Also, I want to set this value to the text-box of the destination form.
For example:
I'd like to transfer the value '5' inside the code VBA of the form 'form1' to the form 'form2'. After moving successfully, I want to show this value in a text-box of the destination form. Please point me to a way of solutions.
Thanks so much...

My question is simple -> can I get full name of assembly in which resides my function that is currently running. To clarify:
<br />
static string ReturnName()<br />
{<br />
return "This function runs in assembly named:"+ Class.Property.ToWhich.U.Need.To.Point.Me<br />
}<br />
Tnx

How about Reflection.MethodInfo.GetCurrentMethod().GetType().Assembly.GetName().Name?
Or something like that.

System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
But you were close
Tnx a lot!

I'm drawing a few shapes on an img field on a windows form by overriding OnPaint, and using a double buffer as many people have detailed here. However, my shapes disappear after they are drawn. If I put a Refresh() at the end of my OnPaint override, it works (but obviously bogs down)If I set a timer it flickers at the rate of the timer.
What am I doing wrong?

Uf, that happend a lot when I first used drawing. What I learned is that drawing directly in OnPaint event isn't good solution in most cases, better draw it in Form_Load for example.
What you must know is that in this case you need refresh you drawing in Form's Activated event... because if you hide ur Form (which happends a lot when in debug mode) and than show it again your precious work will be gone...
If you follow my suggestion and drop function calling in Page_Load then you'll have code like this:
<br />
Form_Load()<br />
{<br />
DrawStuff();<br />
}<br />
<br />
Form_Activated()<br />
{<br />
DrawStuff();<br />
}<br />
In case you stick with OnPaint() I guess simple this.Invalidate(true); in Form_Activated should do the trick.
I guess someone will eventualy give you right answer but if you get stuck, drop a code - that will help us to help you.
cheers

Thank you for the response
I am still a bit confused, however. One of the shapes I'm drawing I'd like to follow the mouse as it moves over the img box - So I would have to refresh() each time the mousemove event triggers, correct?
If I put the refresh() in the mousemove event it seems to work fine as long as the mouse is moving, but as soon as the mouse stops, the shape disappears. This is really frustrating!
Thank you for any help - mutty

This is working for me... even if Refresh in MouseHover is commented... but maybe you should try uncommenting it.
<br />
private void pictureBox1_MouseHover(object sender, System.EventArgs e)<br />
{ <br />
}<br />
<br />
private void pictureBox1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)<br />
{ <br />
Refresh();<br />
}<br />
<br />
private void pictureBox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)<br />
{<br />
using (Graphics g = this.CreateGraphics())<br />
{<br />
PaintEventArgs pa = new PaintEventArgs(g, this.ClientRectangle);<br />
g.SmoothingMode = SmoothingMode.AntiAlias;<br />
<br />
pa.Graphics.DrawLine(new Pen(Color.FromArgb(255, 0, 0, 0)), <br />
new PointF(MousePosition.X-10, MousePosition.Y+10), <br />
new PointF(MousePosition.X-20, MousePosition.Y+20));<br />
} <br />
}<br />
In any case, if you can't get it to work, drop me .cs on pele@zig-zag.net and I'll look into it.
Cheers

Hi!
I was just wondering how I could delete 1 row from the results I get in my datagrid. Everytime data shows in my datagrid, an edit/delete button appears for every row i fetch. Now what I want to happen is that if I fire my delete button only the row aligned to it gets removed. Now my problem is that my page hangs when i click the delete button. I've debugged it and it stops right before my curly bracket
<br />
if (Page.Request.QueryString["Mode"] == "Delete")<br />
{<br />
objCol.DeleteColors(Page.Request.QueryString["key"],"");<br />
Response.Redirect ("SysColors.aspx");<br />
}
<br />
public bool DeleteColors(string strObject,string strColors)<br />
{<br />
try<br />
{<br />
strSQL = " DELETE FROM sys_colors";<br />
strSQL += " WHERE object = '" + strObject+ "' ";<br />
strSQL += " AND c_code = '" + strColors + "' ";<br />
<br />
OdbcCommand cmdDelete = new OdbcCommand();<br />
cmdDelete.CommandText = strSQL;<br />
cmdDelete.Connection = cnnDS;<br />
cmdDelete.ExecuteNonQuery(); <br />
<br />
return true;<br />
}<br />
catch (Exception e)<br />
{<br />
throw e;<br />
}
I hope I didnt forget anything this time...Thanx for all your help! Much appreciated! My apologies for the inconveniences
Kampai!!!

Firstly - what curly bracket ?
Second - is c_code always empty ? If not, this will never do anything
Third - why is your table called sys_colors ?

Third - u must admit that it is fancy name 
And what about Connection.Open()?
|
|
|
|
|
1. The "}" below my if statement
2. c_code always has data in it...but can you please explain to me the concept on why it shouldnt always be empty? Thanx!
3. sys_colors=systems colors. It's a table full of colors for each part of the company website
3.a. I've the Connection.Open(); part above my form.
Kampai!!!

if (Page.Request.QueryString["Mode"] == "Delete")
{
objCol.DeleteColors(Page.Request.QueryString["key"],""); // 2 - you always pass an empty string to compare with c_code, so it will never do anything anyhow
Response.Redirect ("SysColors.aspx");
}// 1. If it hangs here, then there's nothing else for the debugger to show you, it's gone off to another form. Put a break point in the other form to see if it gets there. I assume you've stepped through to see the rest is executed ?
//objCol
public bool DeleteColors(string strObject,string strColors)
{
try
{
strSQL = " DELETE FROM sys_colors";
strSQL += " WHERE object = '" + strObject+ "' ";
strSQL += " AND c_code = '" + strColors + "' ";
OdbcCommand cmdDelete = new OdbcCommand();
cmdDelete.CommandText = strSQL;
cmdDelete.Connection = cnnDS;
cmdDelete.ExecuteNonQuery();
return true;
}
catch (Exception e)
{
throw e;
}
3 - sys_ is the prefix for system tables, so why are you using it ?

oh...darn. About the sys_ its a pre made table by the other programers God knows who. So the 2nd parameter is what keeps it from doing anything coz its set as "".
Yeah everything else is executed except for this delete button and a slight problem in my save button. It's suppose to save the color on only one row however it saves a color i choose for every row. I guess i should explain that a color is asigned for every part of the website. For example the background color is blue then the forecolor is red. What happens is when i choose for example again green to be set as the background color, green is also set for the rest of the parts. Well thats a different problem altogether right...?

There's no naming conventions on this app ?

OK, that's by design for now ?

Yes, sounds like the SQL is flawed there.
So did you try a break point in the other page ? Does the SQL execute ? I guess it's hard to say, seeing as it does nothing right now.

Yeah it the SQL executes then when it goes back to my UI then it hangs at the bracket shown earlier. I've tried removing the Response.Redirect(SysColors.aspx); line then the delete button fires but now it doesn't do anything at all.
Im really sori for all the trouble. Im still learning c#. Thanks for your undying patience
Kampai!!!
