I am able to create a structure inside a structure in vb.net but i am confused as to assign values to the inner structure. I want to send the root structure (which contains the value of its own as well those of the inner structure) to another procedure. Someone please help. Thanks in advance

Something like this?
Public Structure InnerStruct
Public InnerTest As String
End Structure
Public Structure RootStruct
Public Test As String
Public myStruct As InnerStruct
End Structure
Public Class Form1
Public Sub ShowInnerText(ByVal whatStruct As RootStruct)
MessageBox.Show(whatStruct.myStruct.InnerTest)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim newStruct As RootStruct
newStruct.myStruct.InnerTest = "Hello world"
ShowInnerText(newStruct)
End Sub
End Class

Expanding on Eddy's example:
Public Structure InnerStruct
Public InnerTest As String
Public Sub Init
InnerTest = "initialize your vars here"
End Sub
End Structure
Public Structure RootStruct
Public Test As String
Public myStruct As InnerStruct
End Structure
You can have subs etc, within a struct. You can also have a CTOR; although it must have parameters. Just another option for you.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Thank you very much for your help. Your code works fine. You have taught me how to do that. Previously I placed the InnerStruct inside the RootStructure and was groping around. Can it be done that way or was it a wrong approch ? Thank you once again.

|

You mean like this?
Public Structure RootStruct
Public Test As String
Public myStruct As InnerStruct
Public Structure InnerStruct
Public InnerTest As String
End Structure
End StructureThat's valid too. Just don't forget to include a field that instantiates the struct in the RootStruct

Launch a process with ShellExecuteEx, I wanted to ask if it was possible to freeze, pause the process and subsequently restart it?
Of this process for now I have available hProcess(Index) = SIX (Index).HProcess
Thank you.
With SEI(Index)
.cbSize = Len(SEI(Index))
.fMask = SEE_MASK_NOCLOSEPROCESS Or SEE_MASK_FLAG_NO_UI
.hWnd = OwnerhWnd
.lpVerb = "Open"
.lpFile = Filename
.lpParameters = Parematri
.lpDirectory = vbNullChar
.nShow = SW_SHOWNORMAL
.hInstApp = 0
.lpIDList = 0
End With
r = ShellExecuteEx(SEI(Index))

No, it's not possible to "freeze" another process and then restart it. If you don't want it running, don't launch it.

A bootloader is 512 bytes long, and has a specific two-byte signature at the end of the file. It gets loaded at 0x7c00:0x0. You get put in real mode. BIOS interrupts are available. But before you even start writing an operating system, make sure you know C++ and assembly language (especially pointers). If you need to get any more knowledge then go to the OSDev Wiki and read anything you can find. Write some code, and follow tutorials to start with

Thanks Dear,
It's really halpful for me. Can i write for OS Development in MFC VC++.
If you can think then I Can.

Using MFC?? No, you can't since MFC relies on Windows, which, of course, won't exist under your operating system.
|
|
|
|
|
No. If you want a function, then write it. You have no malloc, strlen or strcat. You're on your own in terms of libraries. If you have the base infrastructure, you could port an existing one, but that's a lot further than a bootloader. That said, GrUB does a rather nice job of loading your kernel for you - just don't expect it to be able to load a VB.Net program - that uses the .net framework, which runs on Windows, which you can't use to boot from

You want to run a VB.NET app as the boot program?? Never going to happen, since the .NET Framework relies on the existance of Windows, which won't be loaded if you attempt to do what you want.

Hello Himangshu,
I think when you are showing second report at this time Connection was already open and It generate problem for creating another connection.
So show one report at a time or Create Connection With Crystal Report by using Code and pass user name and password.
If you can think then I Can.

thanks for your reply Anubhava
I am showing only one report at a time...I have show button for each report....all reports and its show button are in different tab-page.
And I have done this through code only.
In this case what could be the problem?

I had a similar problem with a project and was never able to find a very nice solution. Basically I designed my reports off an access database that I was never really going to create or have a copy of on the user's machine. I was planning to just create an in memory dataset that matched the schema and load that with data when passing the data into the report. However, when the app runs the crystal report goes out and looks for the database at whatever file location the design database was at on the development machine. When it doesn't find it displayed the login dialog box. To work around the issue, I was forced to always include a blank copy of the design database with my program, and dynamically set a connection between my report and the design database before loading the viewer (because the path is always going to be different between user machines and the development machine). So typically you would just set the report's data source like this:
ReportDocument1.SetDataSource(dsMyDataSet)
I had to do this (I store my design database in the user application data area:
strDesignDBLocation = My.Computer.FileSystem.SpecialDirectories.CurrentUserApplicationData & System.IO.Path.DirectorySeparatorChar & "MyDesignDB.mdb"
ReportDocument1.DataSourceConnections.Item(0).SetConnection(strDesignDBLocation, "", False)
ReportDocument1.SetDataSource(dsMyDataSet)
I'm not sure if you have the same issue, but maybe this is similar and it gives you a place to start looking. If it IS the same problem, please let me know if you find an easier fix.
