Hi!
I have some problem relating saving datetime variable in SQL Server from C#.net application. i use Datetime.ToShortDateString() while sending parameter to Database. now the format of resulting string depends upon the regional settings of windows and SQL server takes M/dd/yyyy format or ISO format yyyymmdd. I want my application to be independent of regional settings. so i want whatever the regional setting is i should send to DB after converting to M/dd/yyyy format. For this purpose i wanted to override DateTime.ToShortDateString() but DateTime is a sealed class. So what should i Do???
any suggestions??
May God help u solv ur problems as well,thx in advance!!

Don't use a string, use a parameter.

hi friends..
How to set mouse move(cursor movement) with some equal distances (like Autocad)...
|
|
|
|
|
Windows Form have a event MouseMove
The event gives you X and Y pos. After that it is all up to calculation
|

Hi friend..
can u send some sample code
|
|
|
|
|
private void Form1_MouseMove(object sender, MouseEventArgs e)<br />
{<br />
label2.Text = "Pos X: " + (e.X - posX).ToString();<br />
label3.Text = "Pos Y: " + (e.Y - posY).ToString();<br />
int a1 = (e.X - posX) * (e.X - posX);<br />
int a2 = (e.Y - posY) * (e.Y - posY);<br />
int a3 = a1 + a2;<br />
Double a4 = System.Math.Sqrt(a3);<br />
label4.Text = "Relative: " + a4.ToString();<br />
}<br />
private int posX;<br />
private int posY;<br />
<br />
private void Form1_MouseClick(object sender, MouseEventArgs e)<br />
{<br />
posX = e.X;<br />
posY = e.Y;<br />
label1.Text = "Selected: X=" + e.X + " Y=" + e.Y;<br />
<br />
<br />
}<br />
<br />
private void Form1_Load(object sender, EventArgs e)<br />
{<br />
posX = 0;<br />
posY = 0;<br />
}<br />
On windows form override the following events and place four labels. This is a simple math operation.
Edit: This is in pixel. If you write such programs and have zoom level you have to convert to mm ir inchecs.

Hi friend..
i need the cursor will move equal distance..
for example.. the cursor position e.x is 100 and e.y is 50 means... the cursor is in 120,60(e.x,e.y)...How to set manual values as cursor position...
|

Have the container for yours value. Check my sample as having click event. The current position mouse becomes 0,0 and then you can move.
But if you want to prgramaticly move mouse then i dont know. I will try look into MSDN Library

Hello!
I have a class with a bunch of properties. Sometimes I only have a string for which property I should set. Is there some smart way to copy how datatable["NameofDataColumn"] works? So I can call my class´s property as I´ve done in subject-text?
/regards

dt.Columns.Add("Email");
dt.Columns.Add("HomePhone");
dt.Columns.Add("WorkPhone");
try
{
objFolder = objNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
Debug.WriteLine(objFolder.Items.Count + " Contacts found.");
for (int i=0; i < objFolder.Items.Count; i++)
{
item = (Outlook.ContactItem) objFolder.Items.GetNext();
dt.Rows.Add(new object[] {
item.FirstName,
item.LastName,
item.CompanyName,
item.Email1Address,
item.HomeTelephoneNumber,
item.BusinessTelephoneNumber
});

There isn't one. You'll have to write it yourself. All restart does is to start a new instance of the application with the same set of conditions as the original was started within then shut down the current instance.

|

hm..in this case, the "new" instance is startet before the old is killed.
i'm not sure right now if this can be a problem, but i'd prefer to avoid this..

Yes - Which is also how Application.Restart works too. (I naturally assume that you know this already)

Why? You were happy to use Application.Restart if it were available to you.

I were happy because I didn't know the behaviour 
However, it works now.

Call Main again - but don't forget to include an exit condition somewhere otherwise you'll end up in an infinite loop.

calling main again would result in two running applications.
there are some background activities running in my app. in the main thread somewhere i'm waiting until all backgound processes finished. but if a certain time elapsed, i dont want to wait anymore and restart application, since there might be a hangup in any background process.

No it wouldn't. It would be the same application but the starting point is called for a second time.

I'm not sure you are using the word process correctly here. Do you mean process as in a ancillary application (which would be the correct use of the word) or process as in another thread?
If you mean process as in other processes (ancillary applications) then just kill the processes.
If you mean process as in another thread then kill the threads.

i meant process in the thread context.
so i'm gonna kill all running background threads and return to main.
thanks.

No it wouldn't. You're not actually going to create a new process here - why do you think Main would behave differently to any other method, none of which results in a new process?

This sounds like you are getting a bit confused architecturally. Don't restart the application - just kill the threads (be aware that this is really frowned upon though).
