Seems like a convoluted way of doing things to me. If you have the opportunity to redesign it so that the data is stored in a database of some sort rather than text files then you'll have a much more robust solution.
The only way you can detect that a file's contents have actually changed is to read it. The way you can tell if a file has been touched (i.e. written, modified or created) is to inspect the file's creation date or modified date in the file system. At the very least you'll then be able to detect and read only the changed files and not all 56.
As an advanced topic you can also be advised of a file's change of status by some system events, but this is I think beyond the scope of this forum. There are articles on The Code Project that discuss this issue if you wish to pursue it.

I'm using the new report object in .net 2.0. I created a report but when the report runs it displays records I do not want to see. I would like to have a form displayed before running the report that allows the user to define what records they want to see on the report. I think I want to use parameters in my query I'm not sure how to set all this up. Any help on this would be much appreciated!

I have a somewhat complicated problem. I have a project that when it deploys actually has two exe's. One is used as a shell program, it uses an xml file to determine and call the most updated version of the sub program. It then removes any outdated sub programs to clean up the file structure. The issue that I'm running into is that after installing with a windows deployment project and then updating the program (through code already written in the sub program) the shortcuts that were created during the setup/install process no longer work. It throws an error because for some reason it is trying to find the .msi file that it used to install the program. The shortcuts point to the shell program, which doesn't change at all during an update. If I use windows explorer and just click directly on the shell program, it works fine. And creating a NEW shortcut to the exact same shell program works just fine too. So maybe since the file structure around it changed it thinks it's damaged and it's trying to run the setup to fix itself????? I was hoping this would come down to a setting in the setup project that I need to change, but I'm having trouble finding help on it. Does anyone have any ideas how to make this work so my users will not have to delete and then recreate their shortcuts?

Hi Guys
I need a favor again to somebody who had experience with printing report procedure, I have a simple program with a crystal report as the report generate,however when I want to printing out the report I have to running a program which connected to crystal report and click the printer icon on that crystal report preview to printing out my report.
Could you please to tell me the way to printing out my report directly without preview it ?, if you can please tell me the command and show me the complete procedure that I have to follow.
If this command not need a crystal report as the report generate please tell me what kind a program should I use for the main report generator.
Many thank for you
Best regards
ICE

I haven't done it before, but I will in the near future so I've been looking around for similar information. I think to print without using the print preview all you need to do is set the PrinterOption properties of your crystal reports ReportDocument object. Then call the PrintToPrinter method of the ReportDocument object. (This is what I've gotten from Visual Studio 2005) I know this doesn't answer all of your questions, but maybe it can help get you started.

This bit of code seemed to work for me. (I use a PrintDialog control to allow the user to select which printer they want. And again, I am assuming you use Visual Studio 2005.)
Select Case PrintDialog1.ShowDialog
Case Windows.Forms.DialogResult.OK
ProductionWorksheet1.PrintOptions.PrinterName = PrintDialog1.PrinterSettings.PrinterName
ProductionWorksheet1.PrintToPrinter(1, False, 1, 1)
End Select
-- modified at 9:05 Thursday 8th June, 2006
ProductionWorksheet1 is the name of my ReportDocument object which is found in the toolbox under the Crystal Reports section.

Hi
you can use the printOut command of the report.
i.e.
on the click event of the print button....
CrystalReport1.printOut false
the parameter false is used to diable user prompt. the other parameters are self explaining.
(Note: I am using crsytal reports 9 and VB.6)
Bye

VB.net / sql
myrow = DS.Tables("psrec").Rows(0) '1 record - 24 fields
Dim myIntArray(24) As Integer
For i = 0 To 23
myIntArray(i) = myrow(i)
Next
Array.Sort(myIntArray)
maxunits = myIntArray(24)
wat leaves me stumped is that since the array starts from 0, it should end at 23. However, the maxvalue can be found at myIntArray(24). when i print the array using the code,
For i = 0 To 23
Console.WriteLine(myIntArray(i))
Next
I always get 0 for myIntArray(0) for every record and the actual values are displayed from myIntArray(1). Therefore, one value is missed since the array prints till myIntArray(23). The last value is at myIntArray(24).
Can you explain this to me...
With Best Regards,
Mayur

Since you have
Dim myIntArray(24) As Integer<br />
For i = 0 To 23<br />
myIntArray(i) = myrow(i)<br />
Next
you never set the last value in the array, value myIntArray(24)
That is the value which is missed?
However, I would think the array should end at myIntArray(23)

mayhem_rules wrote: Dim myIntArray(24) As Integer
This is an array of 25 items. To declare an array of 24 items you use:
Dim myIntArray(23) As Integer
The number you supply when declaring an array is not the number of items, but the highest index to be used.
I think that there are quite some VB programmers out there who constantly declares arrays that contain one too many items and never realise it, becase it seldom causes any errors.

It's in C# but the idea is the same.
ReportDocument doc = (ReportDocument)crystalReportViewer.ReportSource;
doc.PrintOptions.PrinterName = "Your Printer Name";
doc.PrintToPrinter(1, false, 0, 0);
