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???
Thanks in Advance

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
if this code can help me 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

I am developing an application in .NET to solve VRP, without using ArcGIS Server, but I can not find a complete sample code, I used other samples such as routesolver and get help from them, but I faced Exception in INASolver.Solve that shows I didn't load NAClasses correctly, I will be really thankfull if you could help me.Please!!!
I get COMExecption on the line : INASolver.Solve(...), details:Invalid input in NAClass

line = "==XXXT08746=05/01/09 15:13 112 4 IT 0:01'22 0 #2 ";
string Duration = line.Substring(64, 9).Replace("#","[#]");
int s = Convert.ToInt32(Duration.Substring(1, 2));
int s = Convert.ToInt32(Duration.Substring(1, 2));
int y = Convert.ToInt32(Duration.Substring(3, 2));
int l = Convert.ToInt32(Duration.Substring(6, 2));
int NDura = s + y + l;
---->>>> Error System.FormatException: Input string was not in a correct format.
So what should I do with this ?

This is very silly mistake which u can trace it out.
yueru wrote: int s = Convert.ToInt32(Duration.Substring(1, 2));

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

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.

I don't understand how the code has got compiled!

Submit it to Microsoft critical bugs department

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.

i need to get customer information from a java web service my client app is a C# . instead of calling the web service several times i want to get customer object , to do this i use a customer xsd and generated two classes one for c# and other of java ,then i added those classes to relevant party, in the java web service i create a customer object and fill it with info and send to c#, but in C3 it say that the passed object can't be implicitly cast ,any idea to solve this .

Whenever you modify the java code you need to update the references(proxy classes) in C# and then compile it.
I don't understand your problem exactly but hope this helps you.

I have my form currently set up with a treeview and a listview. The treeview shows all the folders with check boxes and the listview shows the files within the selected folder on the treeview.
I am trying to create a backup program which can successfully backup selected files/folders and successfully restore these at a later time.
My question is if anyone can give me any ideas on how to approach this? I'm thinking I would use an output textfile showing which files/folders were backed up and their fullpath?

Hi,
How do i select the whole listViewItem line (all the subitems of an item) when trying to copy it in the clipboard?
I have a listView with 5 columns. When i try to select 1 row it only selects the first column value not the whole row..
any ideas?
Regards,
Alex

Assuming this is a Windows Forms ListView.
I don't know if it will make any difference to a drag-drop operation, but ListView has a FullRowSelect property, which er... well it does what it says on the tin.

Set the FullRowSelect property to true.
for example,
listView1.FullRowSelect = true;
