Hello,
Do you whant to navigate with the Tab Key?
|
|
|
|
|
Yes, I need to navigation on the screen thru TAB.
Actually, Its MDI form and has two child windows displays side by side. On the first child window, when the focus is on the last control and the user hits TAB, the focus should go to the first control of the second child form.
Thanks in advace for all your suggestion/help

Hello,
I think it's best to watch lostfocus event of the last control.
Then you can set Focus on the first Focus of the child Form.
Hope that helps you!
All the best,
Martin

Hi Martin,
Lost focus can happen even when the user select someother control via mouse. I need to implement TAB navigation. I cannot do this using Lost Control event.
Let me know if there is any other alternative.

Kais

Hi,
I associate a multi-level contextMenu to a control by using contextMenuStrip. I associates right-click events
for each toolStripMenuItem, so there are many events registered
and it seems quite rather inefficiency. Are there any methods
similiar to the Toolbar that only one single click event is needed
for all buttons in the toolbar ?
Thanks

Hello everyone,
I have a regex object with "([A-Za-z0-9ığçöşüİĞÇÖŞÜ]{1})([A-Za-z0-9\sığçöşüİĞÇÖŞÜ])*$".. The pattern I want to implement is beginning with a letter/digit and continue with letter/digit/whitespace
But this pattern matches with something like 'a
Why is that and what can I do to correct my pattern..
Best regards!
PS: is there a way to make the input NOT contain two or more consecutive whitespaces ?
.:: Something is Wrong ::.

You have forgotten the ^ to match the beginning of the text.

Hi
I am displaying the available COM ports in a combo box. But the system gives me the available port names in some order. i wish to arrange it in ascending order. I tried the following
<br />
string[] strPort = SerialPort.GetPortNames();<br />
<br />
Array.Sort(strPort);<br />
listBoxUpDownPort.Items.AddRange(strPort);<br />
But this do.. like this.
COM1
COM10
COM11
COM12
..
COM20
COM21
But i wanted to be like this

How about write a funtion to sort it :
static void Sort(string[] ports)
{
int[] portsNumber = new int[ports.Length];
for (int i = 0; i < ports.Length; i++)
portsNumber[i] = int.Parse(ports[i].Replace("COM", ""));
Array.Sort(portsNumber);
for (int i = 0; i < ports.Length; i++)
ports[i] = "COM" + portsNumber[i].ToString();
}

Hi thanks for ur reply,
I also tried to sort like this
<br />
string[] strPort=new string[] {"COM1","COM20","COM21","COM11","COM17","COM18","COM19","COM7"};<br />
string strTemp = "";<br />
for(int i=0;i<strPort.Length;i++)<br />
for (int j = 0; j < i; j++)<br />
{<br />
if (Convert.ToInt32(strPort[i].Substring(3)) < Convert.ToInt32(strPort[j].Substring(3)))<br />
{<br />
strTemp = strPort[j];<br />
strPort[j] = strPort[i];<br />
strPort[i] = strTemp;<br />
}<br />
}<br />

If i have a class "ClassA" having instance of a unmanaged object in it. and when i created the instance of ClassA. if exception comes then how the unmanaged object release the memory as CLR just release the memory of the managed code/managed object

You'll have to encapsulate all the code where an exception can occur in a try/catch and release the memory in the catch case.

You really should write an internal wrapper class that encapsulates the unmanaged resource. This class should have the responsibility for acquiring and releasing the resource properly and safely.
If you are using .NET 2.0, have a look at the SafeHandle[^] class, which may save you a lot of work and hassle.
Also, you need to make sure you implement IDisposable[^] on your wrapper (or the main class if you don't use the wrapper method). Check out http://www.codeproject.com/useritems/idisposable.asp[^] for more details on implementing the Dispose pattern.

ok i am using .Net 1.1, Suppose i have not used any exception handler and also not implemented the idisposable interface then how the memory will manage.Will this be the memory leakage or unmanage object managed by CLR(if any possible way is there)?

You could use somthing like this.
ListItem item = new ListItem(message,name);
listBox1.Items.Add(item);
|
|
|
|

Hi all,
I am a newbie in C#. Can you suggest me one or two books to start learning C#? I have fair knowledge of C++ and MFC. Also please suggest me some good articles which explains the basics of C# and teaches how to do simple tasks with C#. Thank you very much for your time.
|
|
|
|
|
Just take a look through the beginner articles here. The best way to learn would be to think of a simple application you want to write, start writing it using Google etc to help you. If you become really stuck then post a question here.
I find you always learn more by hands-on-experience
As of how to accomplish this, have you ever tried Google?

Hi,
I have a datagrid that is binded to a datatable (in form of a dataview). I have a requirement that when a particular column in the grid has a value (say 'stat'), then the entire row should be painted in red(the text should be red) else black.
I have extended DatagridColumnStyles for my custom columns. In the paint method, i check for the value in the dataview and accordingly set the forebrush.However, when the user sorts the grid, although it shows the dataview to be sorted, still, the value retrieved is incorrect. I use the row parameter of paint to get the value from the dataview.
Here is the sample code
protected override void Paint(Graphics g, Rectangle rect, CurrencyManager cm, int row, Brush backBrush, Brush foreBrush, bool rightAlign)
{
bool isStatRow = false;
DataRowView rView = null;
try
{
DataView dview = DataGridTableStyle.DataGrid.DataSource as DataView;
if( dview != null )
{
string strStat = dview.Table.Rows[row]["ORD_SCHEDULE_INTERVAL"] as string;
if( strStat != null )
{
string val = strStat.Trim().ToLower();
if( val.IndexOf("stat") == -1 )
isStatRow = false;
else
isStatRow=true;
}
}
}
catch(Exception ex)
{
}
g.FillRectangle(backBrush, rect);
string str = HelperClass.GetString(GetColumnValueAtRow(cm, row), NullText);
if( isStatRow )
{
g.DrawString(str, DataGridTableStyle.DataGrid.Font, new SolidBrush(Color.Red), rect);
}
else
{
g.DrawString(str, DataGridTableStyle.DataGrid.Font, foreBrush, rect);
}
}
The code works when the grid is first painted, but once the same is sorted, this returns me errorneous values and thus paints the color wrongly. I tried using currencymanager.Current also but to no use.
Any ideas???
Please respond

Hello,
I have the SID of a user and the SID of a group. Now I need to check if the user is member of that group... So I think I should get the members and there SID of a group and then check with a for-loop if the SID is present. Is there anyone that knows how I could do that?
