I have installed the Crystal Runtime Library for 64bit and recieve the same error.

Well, it looks like the app is still using the x86 version of Crystal Reports. Try forcing the app to compile as 32-bit (x86) instead of "CPU Any" and see what happens.

From what I've been reading, CR's support for 64-bit is wacky. Take a look at this[^] fine little example, which may solve your problem. And people wonder why I never use Crystal Reports...

Your right it is a 32-bit to 64 bit issue.

The issue is more dealing with
Me.AxAcroPDF1.src = frmWIPAnalysis.fileName

Adobe Acrobat pdf viewer.

Does anyone have an alternative I could use to view pdf in both 32 and 64 bit environments.

Any one with helping hand?

I don't know of any that are "dual mode" (to make up a word).

I think you're going to have to have two different libraries in your installed, one 32-bit, the other 64, and install which ever one is appropriate for the platform in question.

I have a data page header,details and and footer section of crystal report 10. I want to duplicate these sections on the same page so that the same data will be contained on each of these sections and finally printed on a single paper. so that user can finally cut the paper into two pieces. Is that possible to do so or any other solution to this problem

any one with help?

Try sub-reports

Hmm ...
If your main report is nothing but a container for 2 sub-reports and each sub-report has the same definition, then I think you will achieve your goal.

Give it a try. The only problem you may have is that you might need some sort of dataset to be bound to the main report; it should be a single value.

Give it a try. I've used it to produce a single page with 3 cross-tab reports on it; each cross-tab was a sub-report.

Hi David,
Thanks for the reply. I am using stored procedures that require three parameters from the its caller. Based on the data supplied to the stored procedure data will be generated from various table. Can u give me some hint on how to do so using sub-reports. here is my sample code for calling stored procedure to generate report.
dim rpt as new myreportname
rpt.SetParameterValue("@studid", DataGridView1.CurrentCell.Value)
If ComboBox3.SelectedItem IsNot Nothing And TextBox3.Text IsNot Nothing Then
rpt.SetParameterValue("@term", CInt(ComboBox3.SelectedItem))
rpt.SetParameterValue("@academicyear", TextBox3.Text)
GradeReportForm.CrystalReportViewer1.ReportSource = rpt
GradeReportForm.StartPosition = FormStartPosition.CenterParent
GradeReportForm.WindowState = FormWindowState.Maximized
GradeReportForm.CrystalReportViewer1.PrintReport()

Else
MsgBox("Please Set Term and Academic year to Generate Report")
End If

I am grateful for any help you may give me.

with regards,

UPDATING BOUND OBJECT NOT WORKING

Hello,

Am having a problem with updating my underlying business object from my win form grid. I have a class and a collection that implements IBindingList. The class contains a line item collection which is bound to the grid(component one grid). When I enter a new record the object gets the values without any problem and the record is saved. However fetching the same record and editing it, the properties of my object are not updated. I am wondering what it is am doing wrong. below is the code for the classes and collections and form load code. I will really appreciate any help from anyone because at the moment am confused since I thought that by implementing the IBindingList interface the two way update, form to object and object to form, is taken care of.

You don't want much do you? Expecting someone to scan through all your code and find an error. Try using the debugger and see if that identifies your problem.

I'm not looking at this at all. I don't care if the code is nicely formatted. It's just plain rude to post such a HUGE code "snippet".

You post just the RELEVANT code snippets, not the whole damn project!

You're clearly new here, so allow me to explain you a few things.

Firstly, under this forum at the very top there is a message entitled "how to get an answer to your question" or something of the sorts.

It will explain that posting an entire project as such and expecting people to debug it for you is not only ludicrous, rude and unwarranted, but it will generally get you answers like the one I'm writing.

Please post small snippets that revolve around the problem at hand, and if it something simple try searching Google or relevant MSDN documentation first.

Visual Basic Decompiler

Hi!
I need to make reverse engineering on an exe file which is written in VB. I tried VB Decompiler Lite V7.7, vbReFormer(free version) and VbRezQ however they just decompiled the code into native code. what I need to the is get the code in VB is it possible? do you any recommendation about a new tool ?
Thanks!!!

If you are after a VB.NET decompiler I would suggest Lutz Roder's .NET Reflector. I believe it is available via the Red Hat website.

Yes. I also tried it but it doesn't decompile because it complains that CLI header does not exist in the file. Because native applications does not have CLI header.

The program was written in vb.net or vb6?

I am not sure but when I decompiled with VB Decompiler Lite V7.7 version is stated as 5. as I pasted to below.

VERSION 5.00
Begin VB.Form Form8
Caption = "HLBP"
ScaleMode = 1
AutoRedraw = False
FontTransparent = True

You can't use the .NET tools to decompile this application. If it was compiled as P-code, then you might have success with this[^] decompiler. If it's compiled to native format, then you're out on your own - you cannot decompile a native executable.

You could disassemble it, but that would probably cost ten times as much as a complete rewrite from scratch.

As a sidenote; people don't like the idea of other people looking at and using their source-code. They usually put a lot of effort into writing it, and some may choose to use extra safety-precautions like obfuscation. There's a lot of money in protecting executables from what you're trying to do Smile | :)

hande5413-Oct-09 8:31

How can I decide whether code is compiled as P-code or native code? I could only get the native code of the exe file like

Private Sub Txtsex_Change() '46B130
0046B130: push ebp
0046B131: mov ebp, esp
0046B133: sub esp, 0000000Ch
0046B136: push 00402746h ; MSVBVM60.DLL.__vbaExceptHandler
0046B13B: mov eax, fs:[00h]
0046B141: push eax....

moreover I could not open your link. Is it broken?
