This only works if every line is exactly the same length in the file. Then it's easy to calculate the offset and you know how much space you have left. But, if you use the default methods of writing files, then each line is not going to be the same length.

Since this would just execute each SQL command in order, why are you even using multiple threads??

Hi all,
Is there a way to add details to a database from a form?
I'm not really sure about the commands.
help please!
Thanks.

It sounds like you don't know much about databases ? What do you want to add ? tables ? columns ? rows ? A row would be an entry, as in, basic data. The web abounds with examples on how to do that, examples which you'd find much easier to follow than a few sentences offered in a forum reply.

I think u want to save records on a form to a database...
if this is the case then u should have a database containing atleast one table that has the same matching columns as the fields on your form...
and then write a code to save those fields values to your database table

Dear all,
I had used partial class to extend typed dataset(ex. add a method to TypedDataTable) in my windows-base applications and it works well.
But when I try it in a web services project, those extend functions which is visible within web project, but invisible to client.(I create a windows-base application then add web references point to that web project, client application will not be able to use extend function, properties etc.)
Is it true that Extending a Typed DataSet Using Partial Classes is not available in Web Services Project ?
Or is there anyway to enable it ?
Thanks for help.

Hi... is there any coding where I can tell a path is a folder or a file?
private void FileOrFolder(string path){
if(){//// condition is path is a folder
}
else if(){/// condition is path is a file
}
else{/// unknown condition.
}
}

I believe that File.Exists is one way to find out if something is a file.

There is also Directory.Exist in System.IO it is part of File
|
|
|
|
|
in my coding format how should I put it???
if(File.Exist(path)){
}
else if(){ /// Find whether is folder?
}
else{
}
|
|

Assuming you don't already know it's a folder, use Directory.Exists as well.
I assumed you knew it was one or the other, in which case, File.Exists would answer the question

ok thanks...
if it is a folder.. I wish to know whether is there any file inside.. is there a shortest possible coding?
|
|
|
|
|
It's either File.GetAllFiles or Directory.GetAllFiles, returns a string array of file names.

Hi,
\
I have two winform classes in question. One has a combobox. When the use picks a selection, it should display this text in the new class. I ahve this working from combobox to combobox and checkedlistbox to textbox but can't figure out combobox to textbox. Please note that the text in the combobox is a concatenated sql string from two columns, Firstname + Lastname as Fullname. I tried putting Firstname in the constructor and also lastname.
In the first form I have used
private void updatebutton2_Click(object sender, EventArgs e)
{
UpdateRole updateRole = new UpdateRole(Convert.ToInt32 (rolecomboBox.SelectedText));
updateRole.Show();
}
The second one I have said
public UpdateEmp(string Fullname)
{
this.Fullname = Fullname;
InitializeComponent();
}
public string Fullname;
private void UpdateEmp_Load(object sender, EventArgs e)
{
this.FirstnameText.SelectedText = Fullname;
}
}
Thanks. Cant figure it out.

Hi guys, I have the above step working if I store the image from picturebox on the hard drive and then use filestream to save the image. I am trying to skip the step of saving the image on the hard drive and instead save the image straight from the picture box onto a SQL 2000 database. Please help!!!

Save the image to a MemoryStream using Image.Save(stream, ImageFormat)[^] method. From the memory stream, you can read the bytes pieces by piece, just like it was a file. Then you can write those bytes to the database.

Thank you for your response. This works perfect. I appreciate your help.

I know how to read from the database. I was trying to save straight from the picturebox, either way thanks for your response. I got it to work by using memorystream.

I'm modifying my original posting...
If anyone knows of a good *working example* for reading, displaying and filtering as many as 20,000 XML records inside a WinForm, please direct me to said example.
Please do not waste my time with bread crumbs concerning ideas and approaches. I just want a working example. Period.
Thanks in advance! Mark
