I'm not sure whether the so calles old style is the proper way to deal with white spaces. If I recall right its purpose was to deal with names consisting of more than 8 characters. From what In know you deal with white spaces by putting the path between double quotes:
abc.exe "D:\My Documents\myfile.xml"
Try if your shell program recognizes the file this way and if so simply prepend and append a double quote character to the OpenFileDialog.FileName.

Wrap your path in double quotes and it should work
abc.exe "D:\My Documents\myfile.xml"

Hi, I have two datagridviews A and B. I want to set the bindingsource filter of datagrid B with the "Selected Row" of datagrid A. E.g. The customer name is in A, and the corresponding orders of that customer will show up in B.
Usually this would be done with the following code if I was using a ComboBox for A:
this.myBindingSource.Filter = "Name=" + myComboBox.SelectedValue;
But for a datagrid view all i can get is "myGridViewA.SelectedRows". How do I extract the selected row and the corresponding column value (Name) from SelectedRows?
A even better method would be how would this be done if Multi select is turned in datagridview A?

Just googling your question returned answers to your question. Try this site.[^]
A word of warning, I do not think you can have a master/slave relationship with multi select. But you can find out by trying.

Hi,
I have a code fragment that handles dragging and dropping tree view nodes on each other, all in the same tree view.
All works fine, but i want to cancel the dragging operation when two mouse button are presses.
In MSDN is written:
"The QueryContinueDrag event occurs during a drag-and-drop operation and allows the drag source to determine whether the drag-and-drop operation should be canceled. A QueryContinueDragEventArgs specifies whether and how the drag-and-drop operation should proceed, whether any modifier keys are pressed, and whether the user has pressed the ESC key."
Well i put a break point in this event, but in runtime when i press on another button or press another key - nothing happened - that is - i execution does not reach the breakpoint.
I search over the internet, but NADA.
Any help will be appreciated.
elaj.

dataset --> dataset11
table --> searchOnline
column --> url
string[] --> urlString
i want to directly get all the rows in column url came into the urlString
thanks
|
|

i tried this but it wont helped
<br />
url = new string[(dataSet11.SearchOnline.urlColumn.ExtendedProperties.Count)];<br />
dataSet11.SearchOnline.urlColumn.ExtendedProperties.CopyTo(url, 0);<br />
|
|
|
|
|
<br />
url = new string[dataSet11.SearchOnline.Rows.Count];<br />
name = new string[dataSet11.SearchOnline.Rows.Count];<br />
for (int i = 0; i < dataSet11.SearchOnline.Rows.Count ; i++)<br />
{<br />
name[i] = dataSet11.SearchOnline.Rows[i]["name"].ToString();<br />
url[i] = dataSet11.SearchOnline.Rows[i]["url"].ToString();<br />
}<br />
if i write the code as above
name and url array contains same data of url Column
else
if i write it like this then they both contains data from name column
<br />
url = new string[dataSet11.SearchOnline.Rows.Count];<br />
name = new string[dataSet11.SearchOnline.Rows.Count];<br />
for (int i = 0; i < dataSet11.SearchOnline.Rows.Count ; i++)<br />
{<br />
url[i] = dataSet11.SearchOnline.Rows[i]["url"].ToString();<br />
name[i] = dataSet11.SearchOnline.Rows[i]["name"].ToString();<br />
}<br />
please help me it is a true bug or its my mistake ???

I have posted my broblem in several place.. No replys that fixed anything.
I am not sure how this began BUT I have it on several computers I have. Three running XP home, One XP Media, and One running Linux and XP Pro (which crashed!) so it is sitting in the corner! My only thought is I have a bluetooth dongle from LINK-SYSTEMS (not blaiming them) A DBT-120 that loaded a Toshiba stack. Nothing wrong with it but I wanted to use the the Microsoft stack.
Anyway, ..
Using
// Reference registry hive.
Microsoft.Win32.RegistryKey hklm = Microsoft.Win32.Registry.LocalMachine;
Microsoft.Win32.RegistryKey myportsregKey = hklm.CreateSubKey("Hardware\\Devicemap\\Serialcomm\\");
Used to return my bluetooth port COM: ports. The string returns a garbage character at the end of the COM?? string.
I'm using something like
//Display value names found in registry
foreach (String valueName in myportsregKey.GetValueNames())
{
String toport;
//////////////////////////////
// THIS string is returned OK
toport = valueName;
toport += " .. "; // just a separator
// Display ports data found in resistry
// Note that I have seen the extra character as a number.
// Example" PORT8 will display as PORT81.. Or some strange character
// It really screws you up trying to open port 81 when it's really port 8!
// String for my bluetooth ports are returned corrupted
toport += myportsregKey.GetValue(valueName);
portList.Items.Add(toport);
}
YES! I KNOW YOU FOLKS CAN DO BETTER! NOT ME!
Anyway, if I use regedit I can type anything I want into the REG_SZ and it will return as I typed it. BUT, if I reboot and try this I get the extra character after the COMM port.
I assume the registry is written to updating the serial ports.
I WOULD SURE LIKE TO SOLVE THIS.
Reinstalling everything on my computers IS NOT A OPTION!

Hi guys, i'm executing a console application using :
<br />
Process prsAlgorithm = new Process();<br />
<br />
prsAlgorithm.StartInfo.WindowStyle = ProcessWindowStyle.Normal;<br />
prsAlgorithm.StartInfo.FileName = "Lottery.exe";<br />
prsAlgorithm.StartInfo.UseShellExecute = false;<br />
prsAlgorithm.StartInfo.RedirectStandardInput = true;<br />
prsAlgorithm.StartInfo.RedirectStandardOutput = true;<br />
<br />
prsAlgorithm.Start();<br />
<br />
System.IO.StreamWriter swWriter = prsAlgorithm.StandardInput;<br />
<br />
System.IO.StreamReader srReader = prsAlgorithm.StandardOutput;<br />
<br />
swWriter.WriteLine(m_strArgList);<br />
<br />
swWriter.Close();<br />
<br />
<br />
<br />
prsAlgorithm.WaitForExit();<br />
i need to redirect the output of this console application to a textbox on a window form,
but the problem is that i want that every line written in the console application, would be automaticaly written to the textbox (and not wait until the console application has exited)...
i'm pretty sure it has something to do with asynchronousy reading a stream or something like that...?
any suggestions?
Thanks in advance,
Erik.

Hi
what we write in c#
int a;
int *p=&a;
|
|
|
|
|
You can use pointers in C#, but only in code blocks marked unsafe. Usually you use references.
As an int is not a reference type, you have to box it as an object to get a reference to it:
int a = 42;<br />
object r = a;
To get the integer value back from the object, you cast it:
int b = (int)r;
Note that boxing is much less efficient than working with the plain value types directly, as an object has to be created to contain the value.
---
b { font-weight: normal; }
|
|
|
|
|
int a;
int *p=&a
Not sure. But think it is unsafe code, As I remember it worked in the old Bell Labs 'C'.
Sorry, I just had to.. No hate here.. Just sort of 'funnin' ya!
|
|
|
|
|
unsafe
{
int a;
int *p = &a;
}
Compile with /unsafe
