Hello,
I am building an application that requires data to be entered into a control that looks like the Data Grid. Basically, it should mimic the functionality of entering data into MS Excel. I know the Data Grid is primarily used to display data binded to a data source, such as a DataSet. Is there any way to display a blank data grid and use it for data entry? If not, what do you experts suggest that I do to get the results I'm looking for?
One possible solution that I came up with was to bind the data grid to the table that the data is destined for. Next, I would add one row of text boxes that would represent each column below the grid. The user could then add the record to the data grid (and underlying table) by typing the details into the the textboxes below the grid, followed by clicking the "Add" button. However, a grid will not appear unless there is data in the underlying table to be displayed. The empty data grid control does not look attractive on a form.
I remember building an application in vb 6.0 where I got around this by placing textboxes over the cells of the data grid control. However, I can't remember exactly how I did this, or if it would even work with the .NET data grid control.
Any help would be greatly appreciated

I want to add a PictureBox to another form. But when I go from form1 to form2, the picture in form2 won't show. Why is this?
I use this code:
dim frmForm2 as new form
frmForm2.showdialog
I've also tried just frmForm2.show
What am I doing wrong?
Should I create a new picturebox in code?
I need sleep....zzzzzzzzzz
Thank you

I am handling an upgrade from VB6 to VB.NET and want to use the opportunity to improve coding standards and overhaul some old code.
I would like to use the MS Code Advisor to check up the code before going into the transition phase. To do this I would like to extend the set of rules to cover a much broader range of coding standard rules. Apparently the Code Advisor can be extended in two ways; first by using VBScript regexps, obviously somewhat limited in scope; second by implementing the IRuleHandler interface to add your own rule classes. However althought the first is copiously documented (no doubt because it is self-explanatory) the second receives no attention whatsoever, and I can't google it anywhere.
Does anyone, know of docs on the interface and the available support routines?
Thanks
Onuk

i have a program that goes into a folder looks into each subfolder and gets all the .jpg files and stores the file names in an array which i then use to insert the path into a msde database. My problem is either one of two things happen
1.the form freezes but the program still does what it needs to
2.or the program simply just freezes
the machine i am using has 1 ghz processor and 786 mb ram and my uses will not have computers even close to this so anybody have any suggestions?

you mean something like this :
VB:
<font color="blue">Private</font> <font color="blue">Sub</font> Button3_Click(<font color="blue">ByVal</font> sender <font color="blue">As</font> System.Object, <font color="blue">ByVal</font> e <font color="blue">As</font> System.EventArgs) <font color="blue">Handles</font> Button3.Click
<font color="blue">Dim</font> someStuff <font color="blue">As String</font>
<font color="blue">Dim</font> i <font color="blue">As Integer</font>
<font color="blue">For</font> i = 1 <font color="blue">To</font> 4
TextBox1.AppendText(someStuff & " : part : " & i & vbCrLf)
<font color="darkgreen">'/// do your stuff here .</font>
<font color="blue">Next</font>
<font color="blue">End</font> <font color="blue">Sub</font>
putting your stuff to do where it says "TextBox1.AppendText"
<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
{
<font color="blue">switch</font>(twins)
{
<font color="blue">Case</font> ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
<font color="blue">break</font>;
}
}

Thanks. But I don't quite understand how to implement that in my program. It's maybe best to show you the code in question.
<br />
Private Sub K_Sten_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K_Sten.Click<br />
/.../<br />
End Sub<br />
<br />
Private Sub K_Sax_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K_Sax.Click<br />
/.../<br />
End Sub<br />
<br />
Private Sub K_Pase_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K_Pase.Click<br />
/.../<br />
End Sub<br />
<br />
Private Sub K_Klar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K_Klar.Click<br />
/.../<br />
End Sub<br />
<br />
Private Sub Huvud_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
/.../<br />
End Sub<br />
<br />
Private Sub K_Ny_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K_Ny.Click<br />
This is where I want to go back to: Sub K_Sten_Click; Sub K_Sax_Click; Sub K_Pase_Click; Sub K_Klar_Click.
All of my subroutines runs independent of each other.
<br />
<br />
Private Sub M_Avsluta_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles M_Avsluta.Click<br />
/.../<br />
End Sub<br />
<br />
Private Sub M_Om_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles M_Om.Click<br />
/.../<br />
End Sub<br />
//OT

are you saying you want to cause the triggering of all those buttons in an event? so the loop causes these to do something : Sub K_Sten_Click; Sub K_Sax_Click; Sub K_Pase_Click; Sub K_Klar_Click.
<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
{
<font color="blue">switch</font>(twins)
{
<font color="blue">Case</font> ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
<font color="blue">break</font>;
}
}
|
|

|
|
No, I just want those Sub routines to be reset when clicked on a button.
//OT
|
|
|
|
|
Now I have fixed the problem.

wFlags = SND_ASYNC <font color="blue">Or</font> SND_NODEFAULT
x = sndPlaySound(SoundName, wFlags)
<font color="blue">End</font> <font color="blue">Sub</font>
putting your sound file's name where it says "D:\Knock.wav"
hope that helps

Hi,
I have a question regarding the use of a hllapi application to screen scrape in XP. Currently I have a hllapi program that screen scrapes from a 16 bit dos app. to a terminal emulator (Attachmate's Accessory Manager) in Windows 95. The problem in converting this to XP is that the hllapi program uses an INT 7F call and the location in the vector table points to the location of a virtual device driver (vxd's are not supported in XP). I was wondering if there was a way to write a VB hllapi program that would kind of act the same way as the current program but without the direct memory calls. THANKS!!!

Yes, there is a 32-bit Windows specification for HLLAPI, called WinHLLAPI. It's focused on C/C++, but you can call it from VB6/VB.NET through the proper "Declares".
I worked a lot with Attachmate products and most of them support WinHLLAPI. Actually, most 3270/5250 emulators support WinHLLAPI and they normally provide some screen scraping samples.
Other alternatives:
The drawback is that, HLLAPI (which you are using now) and its Win32 counterpart, WinHLLAPI, although fine for single user/single machine applications, it is awful slow and too memory hungry for high-performance server applications, In this case, I discovered that by writing a TN3270 emulator I got about a 15x faster application, also saving several tenths of MB RAM.
If there is a LU6.2 transaction available, I would definitively go for APPC. Microsoft's Host Integration Server can map, through a simple wizard, an APPC to a COM+ component, easily used from VB6/VB.NET.

I've created an interface using C++/ATL which I can then implement in a coclass. What I want to do is to now build a VB COM object which implements the same interface. Is this possible or can VB only *use* a C++ coclass I've implemented in a COM server?

dim thd as Threading.Thread<br />
<br />
Private Sub threadSub()<br />
'Some Code<br />
End Sub<br />
<br />
Private Sub threadLauncher()<br />
thd = new Threading.Thread(AddressOf threadSub)<br />
thd.Start()<br />
End Sub
This makes a thread running threadSub, if you want to keep this thread running you should
add code like this:
While True<br />
<br />
End While
