The best way, is just to draw to a new Bitmap / Image, and then use its save method. And there's only 2 places you can draw: The Screen, and an offscreen image.

If you want to conserve space you could create a vector file.
That is a file that saves the coordinates of the line (start point, end point, line thickness, line colour, anti-aliasing etc) and then just read the file each time you need to a draw the line(s) according to the vectors in the file.

Actually, there are two deployment options in VS. You can create either ClickOnce setup or normal setup... If you are using ClickOnce, you won't be able to registry the dlls to client's GAC..As you were saying about publishing things, I think you are using Clickonce that isn't possible to install dll to GAC..

Ummm,, with code behind when you add data to the datagridview. Can't really give an example since we have no idea what your database structure looks like.

I am looking for an help in the best way to accomplish a sync between two dataset of the same type. Meaning I have a LOCAL and REMOTE version of the database and I'm needing to sync them nightly. I have a web service that will accept a dataset and update the REMOTE version but because of a large amount of data I have a LOCAL copy that represents the REMOTE version.
I first parse in data from flat files into a RAW virsion and need to sync data between the RAW and LOCAL versions, ( RAW will trump the LOCAL).
I then use a web service to pass ONLY the changed data to the REMOTE version of the database.
Overall I'm looking of and easy, processor and memory friendly way to sync this data. Any and all ideas on the topic would be helpful.
I'm listening but I only speak GEEK.

foreach ( dsLogPro.CompaniesRow row_Raw in ds_Raw.Companies.Rows )
{
dsLogPro.CompaniesRow found_Local = ds_Local.Companies.FindByCompanyCode( row_Raw.CompanyCode );
if ( found_Local != null )
{
if ( !found_Local.Equals( row_Raw ) )
{ // raw will trump local
foreach ( DataColumn col in ds_Local.Companies.Columns )
{
found_Local[ col ] = row_Raw[ col ]; // update local with raw
}
}
}
else
{ // this must be a new row
found_Local = ds_Local.Companies.NewCompaniesRow();
foreach ( DataColumn col in ds_Local.Companies.Columns )
{
found_Local[ col ] = row_Raw[ col ]; // update local with raw
}
ds_Local.Companies.Rows.Add( found_Local );
}
}
This is the direction I'm currently moving towards. I don't believe the tables will change but the columns might change in the future so I'm really trying to keep this flexable.

foreach ( DataColumn col in ds_Local.Companies.Columns )
{
found_Local[ col ] = row_Raw[ col ]; // update local with raw
}
ds_Local.Companies.Rows.Add( found_Local );
rowsAdded++;
}
UpdateProgressBar();
}
// This will remove un-needed rows
foreach ( dsLogPro.CompaniesRow row_Local in ds_Local.Companies.Rows )
{
dsLogPro_Live.CompaniesRow found_Raw = ds_Raw.Companies.FindByCompanyCode( row_Local.CompanyCode );
if ( found_Raw == null )
{ // was not present in the raw so remove it.
ds_Local.Companies.Rows.Remove( row_Local );
rowsDeleted++;
}
UpdateProgressBar();
}
}
This is what I have ended up with and would like someone elses opinion on the code.

I've googled for a while and I'm no wiser.
The only lead I found is wmvappend from windows media sdk samples, but it's VC++ and couldent even get it to build.
Any pointers?

Hey ya'll,
I want to retrieve an image from a web page using the clipboard.
The question: I am trying to use the MemoryStream returned by GetData("DeviceIndependentBitmap") and create a bitmap for viewing from this.
I've googled and can't find squat so am asking the pros...I'm currently trying to do it this way;
MemoryStream stream = (MemoryStream)data.GetData("DeviceIndependentBitmap");
Bitmap bmp = new Bitmap(stream);
and I get the following exception: "Parameter is not valid"
Thanks,
Mike

Hi.
I'm writing an application that it use a SQL table for store and read data.
Sometime, I need to list all the registers between two dates, (there is a field of type datetime in the table).
So, I have to objects of type DateTime, ie, d1 and d2. Can anyone help me with the query string to list the registers between these two dates??.
Table name: Table1
Field datetime: birth
Query: "Select * from Table1 where birth > " + d1.toString() + " And birth <= " + d2.toString(); // It doesn't work.
I also tried with "#" characters between DateTime objects, but it doesn't work anyway.
Thanks.
Demian.

You should not use string concatenation since it opens you up to sql injection attacks. Use parameterized queries instead.
