I have used this code to add data to the table with respect to Text Boxes, u can try this for Datagrid with some changes.
string strInsert;
strInsert = "insert into JobEvaluationPlanData" +
"(Plan_Id, Com_Fact, Com_Fact_Def, CF)"
+ "values('" + this.TxtPlanId.Text + "','"
+ this.TxtCompFact.Text + "','" + this.TxtCompFactDef.Text + "','"
+ this.TxtFactor.Text + "')";
if (
this.TxtPlanId.Text != "" &&
this.TxtCompFact.Text != "" &&
this.TxtCompFactDef.Text != "" &&
this.TxtFactor.Text != "")
{
OleDbCommand command = new OleDbCommand(strInsert, datcJobEvaluationPlanData.con);
datcJobEvaluationPlanData.dAdapter4.InsertCommand = command;
//Do the Insert
datcJobEvaluationPlanData.dAdapter4.InsertCommand.ExecuteNonQuery();
MessageBox.Show("New Record Added...");
RefreshData();
TxtPlanId.ReadOnly = true;
}
Thanks

Hello,
There are one Editable Gridview in my winform. This GridView is binded with DataTable. After making some changes in GridView, I want to update the DataTable that is binded to GridView.
I have tried with Grid.Update() and DataTable.AcceptChanges();. but it doesn't work.
So, How to synchronize between GridView and DataTable? OR how can I update the DataTable from DataGrid?
Thanks in advance.

Hi All,
For example im having a string like this "0:30:1A:1E:55:2"
i want to convert this string to "00:30:1A:1E:55:02"
how can i do this.
right now im split the string using ':' and then find the length if its 1 then add 0 in front of it, it works fine for me....
but i think some simpler way must be there....
so plz guide me if am wrong
With Regards
Amjath

Hello,
VS 2005
i have created a small windows application. I am wondering how can i make this into a independent program that can run as a custom action in a setup program.
Is it enough go into the bin directory and use the exe that is in there, and add that to the setup as the custom action.
The windows application uses a picture, is it best to have the picture embedded?
Many thanks for any suggestions.

Why did your post get downvoted?
Here[^] is an article that contains a good example of how to use your own code for a custom action.

Hi.
A few quick questions:
Does C# have any function that will compute crc32?
How can I port C code into C#? Do I have to rewrite it, or is there a quicker way?

No
dfn wrote: Do I have to rewrite it
Yes, that is the easiest way.
There are conversion tools that probably need some postprocessing, for a simple
code snippet it is not worth the trouble.
BTW there are some CRC articles on the CodeProject site...

Hello to all,
I am using a socket server in c# I have created based on one from the code project.
it's an asynchronous server, creating a worker thread for client.
till now only tested with one client connected.
my problem is, when I disconnect a client and the reconnect, I get an exception of type
"An existing connection was forcibly closed by the remote host"
I need my application to operate in a manner that when the client reconnects, it's still
communicating with the server on same "IPEndPoint" and keep receiving messages from it,
as if no disconnection occurred.
P.S
When reconnecting the object still holds the same handle and port but ip is changed to
0.0.0.0
when in debug I am breaking on the spot where i get the exception.
The program stands there and values are LocalEndPoint = {192.168.2.100:5001}
on that breakpoint I dis and reconnect the device, and on the same break I get these
new values LocalEndPoint = {0.0.0.0:5001};
Please help me!!!!!!!!!!!

As .txt opens with notepad as default, with what program .exe opens with?
I am aware, .exe is native to operating system. However i have a packaged program which is embedded into main program and is extracted to temp folder before execution..however with .tmp extention assigned. I can rename .tmp with .exe, I am just digging into windows internals and curious how this works.
I guess somefunction of rundll.dll is capable of executing .tmp files, but i am not quite informed about it.
Also, noticed that installshield and other installers copies executables as .tmp files and later executes them
thanks well in advance.

The EXE files are not opened by some other program, they run as is, that's why
they are called executables ! And they each can have quite different functionality.
This is different from other files (often called documents):
TXT/DOC/XLS/PPT... files always open with the same program (typ. Notepad, Word,
Excel, PowerPoint...)

I have this string :
string number = "%123293395976?;107101637=461?";
and I want to take only this part 293395 and put it in another string.
How can I do it? if you could provide me a code for that problem.
I knew that it could be done by using StringTokenizer or taken it character by character, but I don't know how to do it?
Thank you a lot for your help.

you seem to want to take a few digits out of a sequence of digits;
that certainly is not what a tokenizer would do naturally.
What makes you decide where the start and end of the substring are ?
fixed positions ? depending on earlier characters ?
have a look at String.Substring
if you need more help, try to be clear about what the context is, what those
numbers/digits represent, etc.

These digits are taken from card reader and the digits I want to take from the card reader digits is product name. By this digits I want to take I can check if the product name is inside the database or not.
I tried String.Substring, but it is not provided in my C#.
if you have or implemented any code that can these digits, I would be thankfull.
That is impossible. Look again.
What happens when you try to use it ? Compiler error ? run-time error ?
If so, show the code and the details of the response.
And if you don't know how to use Substring, look it up on MSDN, on Google,
or in all the articles here on CodeProject.

Hello
i have requirement where i need to load fonts which is
specific to my application from a folder but not from installed font directory C:\windows\fonts. I could achive this by embeddeing
the resource file i.e fonts file *.ttf.
but this solution bolts the application's exe
so i tried using AddFontResource() and RemoveFontResource()
followed by SendMessage() with broadcast so that all the applications
at runtime can read those font resource can read the font file from
the system fonts table.
but this is not happening all the applications like wordpad , msword
are able to read the fonts which i added from my application
but i an unable to create the desired font in my application
i am getting the default font as MS Sans sarifi
pls suggest me any solution to this
so that i can understand basics better

You could do this two ways...either through connecting to excel file Excel on Connectionstrings.com[^] or through Office Interop...
Going the connection string route may be the easiest, but the Office Interop way is powerful but a bit too involved to post...

Like this i am now able to read the values, but i am now copying string to string. when i tried declaring s as int array and s = (int) ran.text, i am getting error
how can i convert the ran.text string to s int array
for(int row = 2; row< 12; row++) // loop through first 10 rows excel is
{
ran = (Excel.Range)Worksheet.Cells[row, 1];
s = (string) ran.Text;
MessageBox.Show(s);
}
|
|
|
|
|
s[i]= int.Parse((string)ran.Text);
this is working for me, i dont know whether it is correct type casting or not
