It does move on it's own. How are you reading the file and why are you using the Win32 API to do this?

VB6 or VB.NET ? msdn.microsoft.com has all the GDI+ docs for VB.NET, and my GDI+ articles translate pretty easily to VB.NET also.

Here is the way how to Display records on Crystal report from SQL Server. Suppose You have a database with the name MyDatabase which contains many tables and you want to display records from table1 . To do so you've to follow these steps
1) First Create a new form Say MyReportForm then add
Crytalreportviewer from toolbox
2) Now suppose you want to show the roport when user clicks the Report button .Add follwing lines at top of the form which contains Report button
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
3)Write the following code in the click event for Report button .
Dim FRM As New MyReportForm
Dim rpt As New MyReport
try
Dim LogInfo As New TableLogOnInfo()
Dim LogInfos As New TableLogOnInfos()
LogInfo.ConnectionInfo.ServerName = "."
LogInfo.ConnectionInfo.DatabaseName = "MyDatabase"
LogInfo.ConnectionInfo.UserID = "MyUserName"
LogInfo.ConnectionInfo.Password = "Mypassword"
LogInfos.Add(LogInfo)
rpt.Refresh()
FRM.CrystalReportViewer1.LogOnInfo = LogInfos
( FRM.CrystalReportViewer1.SelectionFormula = "{Table1.SomeField} = " & SomeCriteria & " " )
FRM.CrystalReportViewer1.ReportSource = rpt
catch ex as exception
msgbox(ex.Message & ex.stackTrace)
End Try
Note that Statement in paranthesis is optional only if you want to show records by filtering on the basis of some criteria.

Thank you very much for your answer. But I have a problem with

Dim rpt As New MyReport
this line and
TheOnlyFalcon wrote:
FRM.CrystalReportViewer1.LogOnInfo = LogInfos
( FRM.CrystalReportViewer1.SelectionFormula = "{Table1.SomeField} = " & SomeCriteria & " " )
this line.
The first one is not recognized by the vs.net. It appear the blue line under it. The second one is not correct. Can you give some more reallity example?

Oops!!!!!!!!! Two problems
Your first problem is becuase you may have not added a report to your project to do so from solution explorer right click your project then select add new item from the dialog box selec crystalreport and assign it any suitable name "MyReport" in this case VS.NET will create a class for your report.
Your second problem is because you may not have added a crystal report viewer add it from toolbox if you have still problems then contact me at cyberboy_137@hotmail.com
Many regards

Thank you very much for your comment. I have correct the problem and the code could run without any error. But there is nothing appear on the screen. Here is my code that I used:
Private Sub Button1_Click(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim FRM As New MyReportForm
Dim rpt As New MyReport
Try
Dim LogInfo As New TableLogOnInfo
Dim LogInfos As New TableLogOnInfos
LogInfo.ConnectionInfo.ServerName = "."
LogInfo.ConnectionInfo.DatabaseName = "VSA"
LogInfo.ConnectionInfo.UserID = "kanel"
LogInfo.ConnectionInfo.Password = "scn-co"
LogInfos.Add(LogInfo)
rpt.Refresh()
FRM.CrystalReportViewer1.LogOnInfo = LogInfos
FRM.CrystalReportViewer1.SelectionFormula = _
"{tblAnalysesChildCase.ChildName} = 'eQOn eGOn'" ' & SomeCriteria & " ")
FRM.CrystalReportViewer1.ReportSource = rpt
FRM.CrystalReportViewer1.Show()
Catch ex As Exception
MsgBox(ex.Message & ex.StackTrace)
End Try
End Sub
Thank for your help!!

The problem might be the case of following line .
FRM.CrystalReportViewer1.SelectionFormula = _ "{tblAnalysesChildCase.ChildName} = 'eQOn eGOn'" ' & SomeCriteria & " ")
Actualy this will be interpreted as like a WHERE clause so
if you want to show filtered data on report then you have to use "Correct selelectionFormula" Here i can see you have not written the proper selection formula .
Example
Suppose you want to show the records of those whose ages are under 12 and you have combobox named "cboages" filled with ages of children and the daatbase field is "Child_Age" .Select 12 from cboages then click Button1 or whatever your button name is .
frm.crystalreportviewer1.SelectionFormula="{tblAnalysisChildcase.Child_Age}= " & cboages.text & " "
And to filter data on the basis of some text not numberic value use single quotes
Example
Show records for Allen
you have a textbox named txtname
Enter Allen then click your button .
frm.crystalreportviewer1.SelectionFormula="{tblAnalysisChildcase.ChildName}= '" & txtName.text & "' "
Your problem must be solved now , if there are still problems you can contact me

Hello all,
Does anybody have any idea how to detect mdb files. I really need some advice here. Maybe i should briefly explain what i am doing now.
I am working on this program where i have to print a report for Buyer's Info, Buyer's Label, Supplier's Info and Supplier's Label. Both Buyer & Supplier have a seperate database (SA1.mdb & SA2.mdb). I have created a form with two listbox. The first listbox will load & display the number of mdb files i have in the project folder. In this case i have two (SA1 and SA2). When i select either one from the first listbox, lets say SA1 which is the database for Buyer, the second listbox will then display Buyer Info & Buyer Label vice versa. Then when i select either one of them from the second listbox and proceed to the generate report button, the report will be printed accordingly.
Hmm... does anybody know how to do that? really looking forward to an answer. Thank you!

VB6 or VB.NET ? In VB.NET you can use Directory.FindFiles, which takes a filter, so you can get an array of filenames that end in .mdb.

Hello everyone,
Can i delete a file forcefully at the time when that file is in use by another process.
Thanks.
|
|
|
|
|
To remove a file that is in use by another process, you have to kill the process that has the file open.
Example:
Public Sub TermProc(byval procname as string)
Dim processes() As Process
Dim proc As Process
processes = Process.GetProcesses
For Each proc In processes
If proc.ProcessName.ToLower = procname Then
Try
proc.Kill()
Exit For
Catch ex As Exception
Debug.WriteLine(ex.Message)
End Try
End If
Next
End Sub
Then you could remove the file.
System.IO.File.Delete(path)
|
|
|
|
|
Is there any way to keep that process running and just break the access of that process with that file.
Because that process is of my application. I'm working on some project in which i have to create lot of temporary files and then i need to delete also. Sometimes in a very rare case my application process don't stop accessing some of the files so that i cannot delete those file unless i will close my application.
What do u suggest about it.
|
|
|
|
|
You do not need to figure out how to delete the file, instead you need to figure out what is wrong with your existing code. Because something is certainly wrong!
You are trying to use the wrong approach to fix what basically amounts to a bug.
If a file is open because the application needs it, and another function in the same application tries to delete that file, then obviously there is a bug in your temp file deletion operation.
If there is no bug in the file deletion algorithm, i.e. you know for sure that it never tries to delete files that are stil needed, then you have a file that is no longer needed but cannot be deleted because it is still open. In that case the bug is in your opening and closing of temp files.
Either way it is a bug, period.
Rather than trying to write additional code to force the delete of a file that is "in use" you need to carefully reveiw your existing code and determine what this set of conditions ever arises in the firtrst place.
Robert

No, you can't. If your process doesn't own the handle to the file, you can't get at it. This would be a security violation.

I see a couple of things to check.
1) The error message indicates that an indexed value such as an array is out of bounds.
2) The e.grid.cells if I recall correctly starts indexes as 0. On your line:
Dim RestrictTwelve As String = CType(e.Item.Cells(18).Controls(0), TextBox).Text
May be throwing the error as this could be out of bounds of there are only 18 items in grid.
Hope this helps....

You didn't get the answer that you wanted. I suggest you start searching and reading because the answers that you want are WAY TOO LARGE to post in any forum. Next time, try asking a more specific question about what you don't understand. Don't ask a qeustion about getting a documentry made about the in's and out's of what you want to write.
The ability to do research, on your own, and learn the skills you need on-the-fly is the PRIMARY skill you need to survive in this business.
