Yeah, thanks. I figured it out today - finally found some reference to OpenRemoteBaseKey, and it was easy from there. Only been working in .Net for a couple of months.

i had a oledb connection, adapter and a dataset
now i m trying to bind combobox with my dataset
combobox1.valuemember=dataset11.tables("table1").rows.coloumn(1).tostring
it is not giving any error but it does not show any thing in combobox.
help me
|
|
|
|

There's a ValueMember (what is the value or ID of the object selected), and a DisplayMember (what is actually shown in the combobox:
ComboBox1.ValueMember = DataSet11.Tables("Table1").Columns(1)
ComboBox1.DisplayMember = DataSet11.Tables("Table1").Columns(2)
Also, you told the combobox what the valuemember was, but no what the display member was supposed to be, so of course, the combobox came up blank. On top of that, you called .ToString() on a Column object. This will return the name of the column, not the data in that column.

I have the following simple code to place a background image and an animated image in a picture box. How can I get the animated image to be centered in the picture box?
Dim myPBImage As Bitmap = New Bitmap("Dog.gif")
Dim myPBBkgrd As Bitmap = New Bitmap("BackYardBkgrd.jpg")
PictureBox1.BackgroundImage = CType((myPBBkgrd), System.Drawing.Image)
ImageAnimator.Animate(myPBImage, New EventHandler(AddressOf OnFrameChange))
PictureBox1.Image = CType((myPBImage), System.Drawing.Image)
|
|
|
|
|
PictureBox1.SizeMode = PictureBoxSizeMode.CenterImage

Worked perfectly. Thanks!

Not sure if this is theright forum but....
Does anybody know how to turn off the feature in a visual studio .net setup and deployment project that when you change an installed file it asks you to re-install the whole app.
It is really annoying when you need to swap out a dll, ocx or exe on client site because you need to..(I know you shouldn't have to but this is a rushed job for a very large client) and then it insists on re-install replacing the dll, ocx, exe with the original....aaaahhhhhhhhhhhhhhhhhhhhh!!!!!!!
Thanks for any help on this...
Cheers

This is a built-in function in the Windows Installer service. There is not much you can do about this once the setup has been run. What happens is changing the file causes the Windows Installer to automatically put itself into Repair mode.
You have a couple of options:
1) Reissue the entire setup with the new files, have the user uninstall the original application completely, then install the updated version. This is easy enough for you to do, but your client may not be very happy about it.
2) Author a Patch project. A patch project does several things. First it replaces any files that you need to replace. Second. it finds the original installation MSI and applies changes to the MSI so that it now recognizes the updated files as being the correct ones so Repair mode is no longer automatically in initiated because the versions have changed.
Creating a Patch is way outside the scope of what you can do with the VS.NET Setup projects. You will need to download the Windows Installer SDK from Microsoft to even get started, and authoring MSI's is difficult and tedious.
Good Luck!

The one at www.rustemsoft.com works very well but you do have to pay for it, $35.00, but it does more than just single column comboboxes. It also does multicolumn combo boxes, datepicker, button control on the grid and some others.
I found a number of free, single column comboboxes when I did a web search for datagrid combobox. Actually they were projects that showed how to use the standard vb.net combo box in a datagrid.

Im currently using the VB6.0 to search for data in Access 97's database. But even i can see the comparison showing the same results, it still say "not same" then it just to the next record. Does anyone know about the reocrd searching function in VB6.0? If you know, i wish that you can help me on this matter. the following is my code.
Private Sub SearchRegNum()
Data1.Refresh
Data1.Recordset.MoveFirst
Do While Data1.Recordset.EOF = False
MsgBox "'" & Data1.Recordset.Fields(14) & "'" & " XXXX " & "'" & txtTest.Text & "'"
If Data1.Recordset.Fields(14) = txtTest.Text Then
MsgBox "SAME ==> FOUND"
txtName.Text = Data1.Recordset.Fields(2)
txtID.Text = Data1.Recordset.Fields(3)
txtRegNum.Text = Data1.Recordset.Fields(14)
Exit Do
Else
MsgBox "Not SAME"
Data1.Recordset.MoveNext
End If
Loop
If Data1.Recordset.EOF = True Then
MsgBox "Vehicle Not Registered.", vbExclamation, "error"
End If
End Sub
|
|
|
|
|
Use this
data1.Recordset.Movefirst
if Data1.Recordset.Eof = true then Exit sub
MsgBox "'" & Data1.Recordset.Fields(14) & "'" & " XXXX " & "'" & txtTest.Text & "'"
If Data1.Recordset.Fields(14) = txtTest.Text Then
MsgBox "SAME ==> FOUND"
txtName.Text = Data1.Recordset.Fields(2)
txtID.Text = Data1.Recordset.Fields(3)
txtRegNum.Text = Data1.Recordset.Fields(14)
else
Data1.Recordset.MoveNext
If Data1.Recordset.EOF = True Then
MsgBox "Vehicle Not Registered.", vbExclamation, "error"
MsgBox "Not SAME"
End If
End if
|
|
|
|
|
Use this
please make suse of the exit sub
and make sure MsgBox "Vehicle Not Registered." & " " & " Not SAME"vbExclamation, "error"
:Exit sub is one line
data1.Recordset.Movefirst
if Data1.Recordset.Eof = true then Exit sub
MsgBox "'" & Data1.Recordset.Fields(14) & "'" & " XXXX " & "'" & txtTest.Text & "'"
dd:
If Data1.Recordset.Fields(14) = txtTest.Text Then
MsgBox "SAME ==> FOUND"
txtName.Text = Data1.Recordset.Fields(2)
txtID.Text = Data1.Recordset.Fields(3)
txtRegNum.Text = Data1.Recordset.Fields(14)
else
Data1.Recordset.MoveNext
If Data1.Recordset.EOF = True Then
MsgBox "Vehicle Not Registered." & " " & " Not SAME"vbExclamation, "error"
:Exit sub
goto dd
End if

For some reason, the CurrencyManager will not let me remove the last item in the collection. For example, if I have a CurrencyManager bound to a collection with a Form and Control bound to the CurrencyManager. I can remove any item from the CurrencyManager just fine with RemoveAt. However, if it is the last item , it simply ignores the call. It doesn't throw and error, it simply doesn't do anything. Count remains Same, Position remains 0. Even if I try calling CurrencyManagerVar.List.Clear(),
it ignores the call. Again, no error, just doesn't do anything.
But in my Another form it has worked fine with CurrencyManager.RemoveAt(CurrencyManger.Position)
Any Problem in my code?
My code is :
CurrencyManager.RemoveAt(CurrencyManager.Position)
I have also tried with
Dataview.Delete(CurrencyManager.Position)
And
Dataview.Delete(CurrencyManager.Count-1)
And also with
DatarowView = CurrencyManager.Current
DataTable.Remove(DatarowView.row)
above all are not working

:(I have a legacy COM object that returns a hMem to a block of data containing an large array on int16's. I need to access that data through VB.Net and ultimately pull it into a local array.
I have tried just 'GlobalLock'ing the hMem handle and accessing the memory via the pointer, but that fails. Does this need to be marshalled since it is unmanaged to managed code?
Any feedback would be appreciated

Hey i have been taking a class for vb for the past 5 months or so. I am learning vb versions 5 and 6.
So to the question.
Can somebody provide code that when you click a button ,or someother action, a folder is created on the desktop.

I believe that there's a COM object that you VB6ers use to get any sort of file stuff to work.
Just so you know, your classes are teaching you a dead language. If you're learning for fun, that's fine, I hope you have a ball. If you have hopes of finding a job, then the VB6 pool still exists, but it is rapidly going to die. If you must learn VB ( C# is a far superior language ), then you should learn VB.NET if you want to develop skills you can grow with in the future.

From most of your reply's I've read on this message board you seem to be constantly looking for someone to get you "started".
Let's hear what you have to say about C# being so superior. We are all bowed at your feet and waiting for you to toss all of us ignorant, unwashed masses a few precious nuggets of your infinite wisdom.

Not at all. I come here because the .NET framework and recent experience means I can answer a lot of questions here.

Given the sarcastic tone, I'll give you one reason. C# is not dragged down by bad syntax kept because of legacy coders who are scared to learn something new. Did you know that a group of VB hacks is petitioning Micosoft to keep VB6 ? Man, I've never laughed so hard. What a pack of morons. My background is in C++ but I've learned both C and C# ( as well as lot of other languages, the point is just that I was happy to go forward and backward ) as my job required it. I'd never attack C# for not being C++, that's the point of language evolution.
Any language that invents return values for you is a disaster. A language that is not case sensitive encourages sloppy coding. A language that has never been capable of writing real world applications unless it accesses components written in a more capable language deserves as much respect as the people who cling to it in blind fear and ignorance.
Well, you said you wanted to get me started....

i am learning visual basic .net using visual basic standard ed, and a book called simply visual basic .net by Deitel. in the 2nd chapter it says to start a new windows application project with the name of Welcome, and save it to a location called c:\simplyvb, (which is a folder i made to save all of the projects that i will build in this book) then when i click on the ok button, instead of seeing the form i get the following message; "cannot find c:\programs\microsoft visual studio .net 2003\vb7\vbwizards\windows application\templates\1033\formvb" i have tried building several projects with different names and i get the same message, any suggestions on how to solve this problem would be greatly appreciated,
thank you.
Dave.
