So what part do you need help with ? How much have you done ?
And why do people keep posting here with email addresses ? All you'll get from that is spam, no-one's going to help you if you're not willing to read the site.

I have a DataGrid bound to a DataView. The "RowFilter" property changes dynamically based on which item is selected from a comboBox. The "table" property of the DataView does not change. If I just select different items (Employee Names) from the comboBox the the DataGrid displays the appropriate rows pertaining to that particular employee. However, when I modify some of the employees records (im trying to change data that changes the employeeID from a set of selected rows in the DataGrid). Howerver, when I run the code, the correct number of rows get updated, but all not the rows intended. Actually If I choose 5 rows, only two of the rows selected get updated plus 3 more that are higher in the row index. by the way, I consider myself a newbie (at about 40% or less knowledge)
Here are sections code pertaining to this issue.
/////////////////////////////////////////////////////////////////
/ comboBox population and dataGrid dataSource binding to DataView
/////////////////////////////////////////////////////////////////
// If no selection has been made in the comboBox
if(cbTransferFrom.SelectedIndex == -1)
{
// set the "Table" property of the DataView object
da.dvLeads.Table = da.dataSet.Tables["Campaign"];
da.dvLeads.RowFilter = "";
da.dvLeads.Sort = "Status, APID ASC";
}
else
{
// No need to set the "Table" property again,
// just re-set the "RowFilter" property to filter for the desired rows
// hTable is a Hashtable containing the Employee's Name and the corresponding
// EmployeeID
da.dvLeads.RowFilter = "APID = " + hTable[cbTransferFrom.SelectedItem.ToString()];
da.dvLeads.Sort = "Status, APID ASC";
}
dataGrid1.DataSource = da.dvLeads;
/////////////////////////////////////////////////////////////////
/ Selecting Rows from DataGrid
/////////////////////////////////////////////////////////////////
private void dataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
string temp = "";
// indexArray will hold the rowIndex for the row selected so we can know
// which row to modify later
indexArray = new int[da.dvLeads.Count];
for(int i = 0; i < da.dvLeads.Count; i++)
{
if(dataGrid1.IsSelected(i).ToString() == "True")
{
indexArray[itemsCount] = i;
itemsCount++;
temp = temp + "DataView RowIndex: " + i + " Name: " + dataGrid1[i,4].ToString() + " " + dataGrid1[i,5].ToString() + "\n";
}
}
MessageBox.Show(temp);
lblLeadSelected.Text = "Leads Selected: " + itemsCount;
}
/////////////////////////////////////////////////////////////////
/ Modifying the data in the dataView
/////////////////////////////////////////////////////////////////
string temp = "";
// itemsCount is the length of the indexArray
for(int i = 0; i < itemsCount; i++)
{
da.dvLeads[indexArray[i]][1] = hTable[cbTransferTo.SelectedItem.ToString()];
da.dvLeads[indexArray[i]][2] = hTable[cbTransferTo.SelectedItem.ToString()];
ChangeLeadsDisplay();
str = str + "-";
temp = temp + "DataView RowIndex: " + indexArray[i] + " Name: " + da.dvLeads[indexArray[i]][4].ToString() + " " + da.dvLeads[indexArray[i]][5].ToString() + "\n";
MessageBox.Show(temp);
}
This is the result:
Rows I wanted to change Rows that got changed
1. Employee 1 <-- 1. Employee 1
2. Employee 2 <-- 2. Employee 2 <--
3. Employee 3 <-- 3. Employee 3
4. Employee 4 <-- 4. Employee 4 <--
5. Employee 5 <-- 5. Employee 5 <--
6. Employee 6 6. Employee 6
7. Employee 7 7. Employee 7 <--
8. Employee 8 8. Employee 8
9. Employee 9 9. Employee 9
10. Employee 10 10. Employee 10
11. Employee 11 <--
Any help will be greatly appreciated

I can run a batch file that is in a folder on the local hard drive using "System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi);".
How do you run a batch file that in on the web server?
thanks

You pretty obviously can't run it from the client. You'd need an application running on the webserver that listens for clients and runs the batch file requested.

Hello everybody !!!
I have some question for you...... I have router connect to modem .... 2 computers connected to router..... on one of them i running Remote Server .... from the other one i running Client App that connect to Remote Server , i use connection string like
tcp://192.168.*.*:2301/ServerObj .....
the question is , if i want to connect from outside my network ( internet ) to server , what connection string i use ?? or if there some another solution for this problem ??

If your client is behind a firewall, then you can't the TcpChannel. You can try using the HttpChannel instead. If your proxy server allows HTTP traffic, then it should work fine.

http://wanaddress:2301/ServerObj and it should work ?

Hey!
Consider the folowing string:
string text = "This is a Test\r\nThere is nothing more to it that this\r\n";
If i show this in a list box the \r(CR) and \n(LF) will be switched to boxes!?
Is there any way to show "\r" and "\n" where this signs('\n' and '\r') apare insted?
Best Regards
SnowJim

Hey!
I have found out how to do:
As long as '\r' and '\n' is counting as one char it will be handled as CR nad LF.
By using this
inData = inData.Replace("\r", "\x5C\x72");<br />
inData = inData.Replace("\n", "\x5C\x6E");
The '\r and '\n' will be '\' + '\r and '\' + '\r'.
Best Regards

Hi!
Someone knows how can I implemment an History List in a TextBox?
Something where the User type a word and the control "remember" what the user has typed and shows a list (similar to comboBox) with phrases begining with the word he are writing.
If someone knows where I can get a sample or something, please help me!
Thnks in advance.
Best Regards
Robert

Search for auto-complete or auto-completion. Those words should get you to a sample that will help you out.

Hi, I have the following regex pattern declared:
private const string ParamPattern = @"(?<name>@\w+)='(?<value>.*?)'";
this is used to match all occurences of eg/ @myVar='myVal' in a string which may have multiple "params". The whole string often looks like:
somthing[@myVar1='myVal1'][@myVar2='myVal2']
so the above would find 2 matches using my regex. Here is my problem... if one of the variables has a single quote it gets cut off ie/
myTestVar='my apostrophe'd val'
the group called "value" in my regex only matches up to the apostrophe. I can easily replace 1 apostrophe with 2 so it becomes
myTestVar='my apostrophe''d val'
but I cant work out how to change my regex to ignore double apostrophes in the value group...any help appretiated.
|

Well, you could use zero-width assertions:
string s = @"myTestVar='my apostrophe''d val'";
Match m = Regex.Match(s, @"'(.*?)(?<!')'(?!')");
if (m.Success) Console.WriteLine(m.Groups[1].Value);
output: my apostrophe''d val
The (?<!') asserts that the character before the apostrophe (used in the match) is not an apostrophe. And the (?!') asserts that the character after is not an apostrophe.
