Disable the add button on the click event of the add button and enable it back when you think it is appropriate.

I understand how to embed cmd.exe into a VB.net form and redirect output but I want to use other utilities such as pstools.exe from sysinternals to redirect its output to cmd.exe from within my vb.net app. Im trying to set up a package to check status of users on a domain/network.

Didn't you mean you want to hook and read the output of the pstools? Redirecting it to cmd.exe would cause the output (of pstools) to become the input of cmd.exe.

Hi,
I know how to open a word document vb.net but i have been trying to open it inside a form with no luck. Can anyone guide me on how to do that?
Thanks

You can insert one managed Form into another by setting the former's TopLevel property false, and its Parent to the latter. You need to do something equivalent to Word's main form (which isn't a managed Form).
So this is what I would try: open the Word process with Process.Start, then invite its main window into your Form by setting its parent (use P/Invoke to call SetParent[^] in user32.dll); I don't know about the native support for TopLevel, I can only hope you won't need it.
Here is my first try in VB.NET:
Private Sub btnWord_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWord.Click
Dim p As Process = Process.Start("H:\test.doc")
Dim word As IntPtr = p.MainWindowHandle
Dim panel As IntPtr = Me.Panel2.Handle
SetParent(word, panel)
End Sub
<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Public Shared Function SetParent(ByVal hWndChild As IntPtr, ByVal hWndNewParent As IntPtr) As IntPtr
End Function

No way.
VB.NET doesn't support this.
Only by opening word.
|
|
|
|

you can open MS Word (or any other app) inside your managed form, as I already told him days ago. Of course it needs Word, but it does not need a separate main window.

Hi Luc,
yes, I agree, your solution works. But you are opening the word application and you just set a new parent to the word main form.
My understanding of the question was, just to open the word document inside a vb.net form (or any other form). Richtextbox (or any other control) can not open a worddocument. So is seems to be impossible just to open a word document for display similar to a richtext file in a richtextcontrol.

So i have a basic idea of an application i want to build in my head. It involves having to add a menuitem to the Shell/Explorer ContextMenu of Windows. Here's how it should work.
1. On first time use, you are to install the menuitem by clicking a button. There's also an uninstall button to remove the menuitem from the shell contextmenu.
2. Then, once it's installed, this menuitem only shows up when you rightclick on one or more files with the .bsp file extension.
3. When you have one or more bsp files selected, you rightclick on one of them to make the contextmenu appear. From there, you click the new menuitem.
4. Then i want a form to show up with a listbox. This listbox should hold the full paths to the bsp files that the user had selected.
I got as far as point 3 and im stuck on point 4. How do i go about getting the paths of the selected bsp files into the listbox on that form?

Nobody knows? There must be way to get this to work.
Im able to retrieve commandline arguments using the %1 parameter, but if i select more than one bsp files and click the menuitem in the explorer contextmenu, Windows launches multiple instances of my application. I just want it to start once, and add the path of all the selected bsp files added to a listbox.
I've also tried the %2, %PATH% and %L parameters but none of them work.

Hi,
Earlier I used only Crystal reports. I never used any RDLC reports. Now I try to use it in VS2010.
As like usual I added one Dataset [xsd] and it contains Datatable1.
Now How can I use this Dataset1? & DataTable1.?
And from my program Button1_Click
Dim MyDtbl1 As New DataTable, NRow As DataRow
MyDtbl1.Columns.Add("one", Type.GetType("System.String"))
MyDtbl1.Columns.Add("two", Type.GetType("System.String"))
MyDtbl1.Columns.Add("three", Type.GetType("System.String"))
For J As Integer = 0 To 10
NRow = MyDtbl1.NewRow
MyDtbl1.Rows.Add(NRow)
MyDtbl1.Rows(J).Item("one") = J + 1
MyDtbl1.Rows(J).Item("two") = J.ToString
Select Case J
Case 0
MyDtbl1.Rows(J).Item("three") = "zero"
Case 1
MyDtbl1.Rows(J).Item("three") = "one"
Case 2
MyDtbl1.Rows(J).Item("three") = "two"
Case 3
MyDtbl1.Rows(J).Item("three") = "three"
End Select
Next
ReportViewer1.Refresh()
ReportViewer1.LocalReport.ReportPath = "C:\CodeProject\My Documents\Visual Studio 2010\Projects\MyReportPjct\MyReportPjct\Report1.rdlc"
ReportViewer1.LocalReport.DisplayName = ?????
ReportViewer1.LocalReport.DataSources.Clear()
Dim MyRptDtSource As New Microsoft.Reporting.WinForms.ReportDataSource
MyRptDtSource.Name = ???????????
MyRptDtSource.Value =???????????
ReportViewer1.LocalReport.DataSources.Add(??????)
ReportViewer1.LocalReport.Refresh()
ReportViewer1.Visible = True
Any Ideas For Me !!!
Thanks & Regards

Anyhow I found the answer and let it be useful to someone like me....
ReportViewer1.RefreshReport()
Dime RpDs1 As New Microsoft.Reporting.WinForms.ReportDataSource
'Here We have to mention the actual Report's Dataset Name
RpDs1.Name="DataSet1"
RpDs1.Value=MyDtbl1
ReportViewer1.LocalReport.ReportPath="C:\CodeProject\My Documents\Visual Studio 2010\Projects\MyReportPjct\MyReportPjct\Report1.rdlc"
ReportViewer1.LocalReport.DataSources.Clear()
ReportViewer1.LocalReport.DataSources.Add(RpDs1)
ReportViewer1.RefreshReport()
ReportViewer1.Visible = True

Hello,
I was reading an artical and there was a line of syntax I hadn't seen
before and I'm curious what is it doing behind the scenes:
Dim v as single = 2293.22
Dim sh as short = New Short?(v)
Short doesn't have a constructor so how did the '?' allow it?
Thanks.
Nathan

Erik,
Re-looking it, it obviously has something to do with nullable types but do you have
any idea why declaring it as nullable allowed a constructor?
Thanks,
Nathan.

Yes, declaring a variable as Nullable(of T) is the same as using T?, where T would be the underlying value type, so for example:
Dim s as Nullable(Of Short)
Dim s as Short?
These two declarations are equivalent. The reason why you can use a constructor is just becouse Nullable(Of T) has one. Replacing Nullable(Of T) with the underlying T? does not change that fact. Here in spain just call it a "syntactical sugar".

Very helpful. Thank you for the explanation.

That's very interesting. I have never seen that either.
