Thanks!!!

Unfortunately, installation is not an option. This program runs on a stick and has to be darn near instantly accessible to whatever machine the stick is put in.

Thanks again.

I don't think you'll be able to use Crystal without installation.
When you install the Crystal runtime it installs hundreds or thousands of files in different directories.

So convert the code. There's plenty of online conversion utilities. All you have to do is Google for "vb.net c# code conversion".

There are plenty of convertors available on net, or you can convert it on your own. Or try your luck with Google.

You will benefit more if you do the C# to vb conversion yourself (with Googles help on Keywords)

Hi,

this is a C# example, you can do the same in VB.NET; there are two key factors:

1. using DirectoryInfo.GetFiles() returns an array of FileInfo which holds name and dates for each file;
2. implementing the IComparer interface to tell Array.Sort how exactly it should perform the sort.

public class CPTest_Sort : IComparer<FileInfo> {
	public override void ListDirOrderedByCreationDateTime(string dirname) {
		DirectoryInfo di=new DirectoryInfo(dirname);
		FileInfo[] fis=di.GetFiles();
		Array.Sort(fis, this);
		foreach(FileInfo fi in fis) {
			log(fi.Name.PadRight(30)+fi.CreationTime);
		}
	}

	public int Compare(FileInfo fi1, FileInfo fi2) {
		DateTime dt1=fi1.CreationTime;
		DateTime dt2=fi2.CreationTime;
		if (dt1<<dt2) return -1;
		if (dt1>dt2) return 1;
		return string.Compare(fi1.Name, fi2.Name);
	}
}

Error in ADO.Net application

LostMonkey30-Jun-09 23:05

Chaps and Chapettes,

I am getting the following error in my wee data application: -

Cannot set column 'vcGraphicCode_GRA'. The value violates the MaxLength limit of this column.

The code does a pretty standard create a new row via a oRow = table.newrow() statement, then populates oRow.<list of="" columns=""> with a set of values (no nulls here btw). Then does a table.AddRow(oRow)...this is when I get the error.

The particular column in the error is a string of 5 characters (a SQL 2005 varchar(5) column). The value I place in there is for example "00152". The table I am inserting the row into is always empty (since the table is on a form for setting up new SKU items). The table is also pre-defined in an XSD file within my project.

Yes, the error informative is pretty straight forward. However, the maximum size of the field is 5 characters and the value I am attempting to place into it is exactly 5 characters in length.

I'm beginning to think that sticking with VFP, where this operation would be a straight INSERT on a remote view, would be easier! Laugh | :laugh:

So there would be some length problem?
you did not try making the field a VARCHAR(6) or the data somewhat shorter, say "0152", did you?
you did not think about a terminating NULL character that also needs to be stored, just like C does?

Hmmm | :|

Hi Luc

No, the string being returned is EXACTLY 5 chars in length. The column on SQL 2005 is a varchar(5). However things are not getting that far...

What is happening is that my 5 char string is being rejected, not by the row, but by the table in my dataset - which is in an XSD file based on my SQL 2005 schema. It seems strange since I am creating the row from the table (table.NewRow) AND I can put the data into the new row and look at it via debugger.

My problem occurs when I do a table.AddRow(Row) - THEN it complains that the data is too big.

If the string was too long, say 6 chars or more, then I would just expect truncation to occur...not an error.

did you try with a string of length 4 or didn't you?

Then I don't know.

I do know MySQL accepts ans correctly stores strings with n chars when VARCHAR(n) was specified, however it does issue a warning when you do this. I suspected your DataTable operation did not like the warning.

Something else must be wrong then.

Smile | :)

Without a shadow of a doubt yes!

The thing that is puzzling me is that the schema is garnered from the SQL 2005 schema.

The row behaves.

It's adding the row to the table in my dataset that causes the error...I've not even fired it back to the SQL 2005 database yet!!

I'll give up and do it in good old (and I MEAN old!) VFP!!
