I have a DGV with checkboxes, a method processes each row and when complete unchecks the row.
This works fine, click the button and the form freezes and returns sometime later with all the boxes unchecked.
Now I introduce a separate thread to do the processing, split out the UI update and use the following to uncheck each row as it completes.
this.BeginInvoke((MethodInvoker)delegate
{
UpdateGrid(oRow, iRecords);
});
private void UpdateGrid(DataGridViewRow oRow, int iRecords)
{
oRow.Cells["Records"].Value = iRecords;
oRow.Cells["Sel"].Value = false;
}
This works fine EXCEPT the first row (which happens to be selected but this is irrelevant) does not uncheck.
Slap a break point on and the index is hit and the first row is unchecked properly so I hit F5. Now the 2nd row is left checked. Seems there is an interaction between the debugger and the thread processing.
Has anyone else seen this type of behaviour?

Dear All,
I am inserting data into Access Database using Update Queries same as store procedures in MSSQL 2005, i am passing params like following
OleDbCommand cmd=new OleDbCommand("queryName",p.con);
cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.Add("@p1", OleDbType.SmallInt).Value = secId;
cmd.Parameters.Add("@p2", OleDbType.SmallInt).Value = comDivId;
cmd.Parameters.Add("@p3", OleDbType.VarChar).Value = prob;
if (p.con.State!=ConnectionState.Open)
p.con.Open();
cmd.ExecuteNonQuery();
this works fine.
now i would like to get the equivalent insert statement of this query
after the statement cmd.ExecuteNonQuery()
how should i get the insert statement equivalent to this update query (store procedures)

If I understand correctly, you'd need a different stored procedure to do the insert, most probably with the same parameters so the code you have above would work with both - just change the "queryName"

this is cool solution,what i want, this is not the answer
i want my store procedure equivalent insert statement.
I would like to get the log of insertion,deletion,update of my queries and save these statement as a separate row in table called "tblLog"
I want to save only the sql statement into a row in the log table.

Hi,
I'm using winchm tool to create help file and its extension is wcp
and i need to call this file in c# Application.How?
|
|
|
|
|
Use System.Windows.Forms.HelpProvider(available in the ToolBox) and assign the .chm (or.wcp) file to its namespace property. On pressing the F1 key, the help file will be shown.
[Edit]:Not sure if it works for .wcp extension.

hi everybody
i m doing a small banking application
i have three tables master,transactions,ledgers
if i m entering the opening balance from master table it inserts in the ledger table and display that value properly.
if i update that value in master it updates ledger value properly.
i enter the values in grid view and save them
they are saved in ledger table as well as corresponding tables.here i m using storedprocedures for saving values.
ledger table is read only it displays only report in gridview
**transaction table have 3 columns
-------------------------------------------
date | deposit | withdrawl
-------------------------------------------
**my ledger table have 4 columns
-------------------------------------------
date | deposit | withdrawl | balance
-------------------------------------------
now the task is
if i enter amount in 'deposit'column of 'transaction table's gridview' ,it displays in deposit column of ledger gridview
for suppose
i enter amount in 'withdrawl 'column of 'transaction table's gridview' ,it displays in withdrawl column of ledger gridview
now balance will be calculated and displays in balance column of ledger's gridview
how can i calculate and displays in gridview of ledger
-------------------------------------------------------------------
date ------ deposit---- withdrawl-----balance
-------------------------------------------------------------------
1/1/2000----1500-----------0----------1500
2/2/2000------0----------1000----------500
3/3/2000-----700-----------0----------1200
4/4/2000------0-----------200---------1000
------------------------------------------------------------------
like this i need
hope u help me n this issue
with regards,

I don't see the problem, you write the transactions back to the database, presumably you have a proc to supply the ledger data so recall that proc after each transaction entry.

Hi,
I'm doing some Microsoft Word automation using Microsoft.Office.Interop.Word namespace,
in this application i'm opening a file (template.docx) and making some changes in it and then saving it.
Just when the file is going to be opened:
myWordDoc = myWordApp.Documents.Add(ref filename, ref missing, ref missing, ref missing);
i receive this exception:
Word was unable to read this document. It may be corrupt. <br />
<br />
Try one or more of the following: <br />
<br />
* Open and Repair the file. <br />
<br />
* Open the file with the Text Recovery converter. <br />
but i'm sure the file is not corrupt, i can open it in word and its data is correct.
Whould anyone please tell me what should i do now???

i need some information on this project if any wud like to help me out on this plzzzz......
I need the following:
1. The software tool must work over network, so that any user on his client station can manage or create VOIP accounts with different access control.
2. We get from the VOIP-Provider the Login & Password for each Phone number. We must create approximately 50,000 VOIP logins by the provider For our “Order Service” by each client WE MUST know on the “Softphone Client” from what registered phone number come the call with the registered Name by the VOIP provider.
3. We will install the Phone client Software later on each workstation to connection to PBX server
4. The PBX server MUST run on the VPN line. If the VPN line cuts any technical reason MUST immediately cut all VOIP registrations to provider and wait that the VPN is working and automatically registered again ALL registered VOIP numbers by provider.
5. To the tool MUST existing following function: One time in the month (so that we not loose by the provider the phone number) must call each registered phone number the other registered phone number! Not only ringing the number also has automatically to take the call for 1 second and hang up and take the next phone number.
6. When we added more VOIP accounts must also automatically added to the function under NUMBER 5!
i have got some source from this site i think u guys shd check this out

Hi,
how can open office be used in .net web/windows application for converting excel to pdf
Thanks
|

Why do you need to use open office to create a PDF? 
There are plenty of PDF libraries that you can use from your app and when I did a search, there's someone who has already done what you need. It's called ExcelReports[^].
It is a crappy thing, but it's life -^ Carlo Pallini

line = "==XXXT08746=05/01/09 15:13 112 4 IT 0:01'22 0 #2 ";

int y = Convert.ToInt32(Duration.Substring(3, 2));

This is very silly mistake which u can trace it out.

In above four lines, check wat is the value of (Duration.Substring());
it may be null or may not be in format to convert to integer.

Finally what is the value you are expecting in the
Duration string ? Do the debug and verify if it has the desired value or not...

The quick answer:
int s = Convert.ToInt32(Duration.Substring(1, 1));
Why?
Try changing your code to this:
String line = "==XXXT08746=05/01/09 15:13 112 4 IT 0:01'22 0 #2 ";
string Duration = line.Substring(64, 9).Replace("#", "[#]");
string a = Duration.Substring(1, 2);
string b = Duration.Substring(3, 2);
string c = Duration.Substring(6, 2);
int s = Convert.ToInt32(a);
int y = Convert.ToInt32(b);
int l = Convert.ToInt32(c);
int NDura = s + y + l;
You will discover that duration equals " 0:01'22 " and so the string you are trying to parse is "0:" - thats why you keep getting the error.
Also this line:
string Duration = line.Substring(64, 9).Replace("#", "[#]");
Is kind of wierd as the Replace has no effect - as I mentioned Duration == " 0:01'22 ". No "#" there...

Thank you
I 've got it even if I've made alot of mistake like u said
now is my code
string Duration = line.Replace("'", "[']");
string LineOO = line.Replace("#", "[#]");
string Date = line.Substring(12, 8);
if (line.Substring(11, 1) == "=")
{
string Time = line.Substring(21, 5);
string Linein = line.Substring(27, 10);
string Lineout = LineOO.Substring(38, 1);
if ((string.Compare(Lineout, "0") > 0 || string.Compare(Lineout, "0") == 0) && (string.Compare(Lineout, "9") < 0 || string.Compare(Lineout, "9") == 0))
{
string Number = line.Substring(40, 20);
string Status = line.Substring(61, 3);
string NDuration = Duration.Substring(64, 10);
string b = NDuration.Substring(3, 2);
string c = NDuration.Substring(6, 2);
int y = Convert.ToInt32(b);
int l = Convert.ToInt32(c);
int NDura = y + l;
string Cost = line.Substring(75, 3);
string Detail = line.Substring(79, 2);
string Network = line.Substring(82, 8);
and it work
Thx

There is still room for some improvement. 
Instead of getting a one character string, you can get a character. You can change this:
if (line.Substring(11, 1) == "=")
to:
if (line[11] == '=')
You can use the >= operator instead of doing both > and == comparisons. You can change this:
if ((string.Compare(Lineout, "0") > 0 || string.Compare(Lineout, "0") == 0) && (string.Compare(Lineout, "9") < 0 || string.Compare(Lineout, "9") == 0))
to:
if (string.Compare(Lineout, "0") >= 0 && string.Compare(Lineout, "9") <= 0)
However, you can use a char instead of a one character string there too:
char Lineout = Line00[38];
if (Lineout >= '0' && Lineout <= '9')
or simply:
if (Char.IsDigit(Line00, 38))
Despite everything, the person most likely to be fooling you next is yourself.

Wowwww
It's so short and simply but I've never knoww.
thx very much
Code is ok but I 've just want to know how to decrease time to do it coz I have 10,100 data and it took a long time.

I while back I wrote this method that you can use to replace Int32.Parse, and that is about ten times faster. That could help to speed up it a bit.
public static int ParseInt32(string text) {
long value = 0;
long sign = 1;
bool first = true;
foreach (char c in text) {
if (c >= '0' && c <= '9') {
value = value * 10 + c - '0';
} else if (c == '-' && first) {
sign = -1;
} else {
throw new FormatException();
}
first = false;
}
value *= sign;
if (value < int.MinValue || value > int.MaxValue) throw new OverflowException();
return (int)value;
}
Despite everything, the person most likely to be fooling you next is yourself.
