I'm writing an ASP.net web page to create new users, and its all going very well. I can create users, set almost all of the AD fields and configure a password. The one thing that is bugging me is the profile path field (profilePath in AD). Everytime it attempts to commitchanges, it bombs out. I've tried changing the format I send it in from \\servername\sharename\username to \\\\servername\\sharename\\username (this is how the output of csvde displays this AD field). Its not a permissions thing as I've set the path where the share and NTFS permissions are set to full control for everyone. I'm now configuring 20 or so AD fields, but this one is going to drive me mad!!!!
This is the section of code:-
Dim ADLocation As New DirectoryEntry("LDAP://DCNAME/" & LDAP_PATH, "domain\accountname", "password")
Dim NewUserAccount As DirectoryEntry = ADLocation.Children.Add("CN=" & txtSamAccountName.Text, "user")
.
.
NewUserAccount.Properties("profilepath").Add("\\servername\sharename\username")
NewUserAccount.CommitChanges()
Any help much appreciated.

I was wondering if anyone has had experience in displaying DXF or DWG files (file type produced by AutoCad - a design application) within vb.net. An example of code would be great
Cheers

Hello Simon,
Ok I have done something similar for my company. You can go 2 ways.
First way: Using the OCX control called DWGTHUMBNAIL.OCX. This one can only see DWG and in a small preview window. It should be part of your AutoCAD. If not you can look on the internet. I don't remember from the top of my head for the address though. Any ways. The code for first way:
'===========================================
Private Sub File1_Click()
On Error Resume Next
File1.SetFocus
DwgThumbnail1.Visible = True
If Right(File1.Path, 1) = "\" Then
fullpath = File1.Path & File1.List(File1.ListIndex)
Else
fullpath = File1.Path & "\" & File1.List(File1.ListIndex)
End If
DwgThumbnail1.DwgFileName = fullpath
End Sub
DwgThumbnail1.DwgFileName = fullpath
'===========================================
DwgThumbnail1 = The name of the control DWGTUMBNAIL.OCX in your form
File1 = The FileListBox control
fullpath = the path of your dwg drawing.
Second way:
Using a OCX control from Invisio. I am not sure if this control is freeware or not. Please check before use.
Code for this:
//==============================================
Private Sub File1_Click()
On Error GoTo Err_han
If Right(File1.Path, 1) = "\" Then
fullpath = File1.Path & File1.List(File1.ListIndex)
Else
fullpath = File1.Path & "\" & File1.List(File1.ListIndex)
End If
DwgThumbnail2.FileName = fullpath
Exit Sub
Err_han:
MsgBox "File is in use. Please try later.", vbInformation, "File in use"
//========================================
DwgThumbnail2 = the name of the INVISIO.OCX control in your form.
File1 = The FileListBox control
fullpath = the path of your dwg drawing.
Please not that the above code work OK in VB6. I haven't tryed it in VB.NET but i don't think it would be any problems. Hope this helps.
Still trying to find the way

Hello,
I need some help in image control. When I press the next button on the form the image should be change with next record and similarly with previous and last buttons.
|
|
|
|
|
what kind of a question is that?
|
|
|
|
|
You should change the Picture property of the image manually.
Image1.Image = Image.FromFile ("Image.gif")
|
|
|

I suppose that you use VB6 as the interface and ms access as the database. In you access file create the table that you want to store an image path. In that table suppost that you have many field with difference information in clude the field of the photo too. In the field of your photo, don't use OLE object as the data type. Use Text as the database instead of OLE Object. Then on your form when you want to select the picture you will use common dialog to open the picture that you want and return the string of the picture path. Use LoadPicture function in vb6 to load the picture base on the path to that picture. So when you add the record you will add the string of path to the image in your record.
Working with this way is save your database a lot of space instead of using an OLE Object. When you move back or next you just load the picture by using the path that store in the database. I used to do this before and its working very well

Hi All,
I have a VB6 project which uses OleCreatePictreIndirect to create a bitmap.
When this is converted to VB.NET (a change forced on me but IT services) it no longer seem to work. The code compiles but throws a;
SystemNullReferenceException: Object not set to instance of an object.
Code used is below and was originally sourced from the standard microsoft example.
Public Declare Function OleCreatePictureIndirect Lib "olepro32.dll" (ByRef PicDesc As PicBmp, _
ByRef RefIID As GUID, ByVal fPictureOwnsHandle As Long, ByRef IPic As IPicture) As Integer
Private Function CreateBitmapPicture(ByVal hBitmap As Integer, Optional ByVal hPalette As Integer = 0) As System.Drawing.Image
Dim r As Integer
Dim Pic As PicBmp
Dim IPic As IPicture
Dim IID_IDispatch As GUID
Dim PicTypeBitmap = 1
' Fill in with IDispatch Interface ID
ReDim IID_IDispatch.Data3(0)
ReDim IID_IDispatch.Data4(7)
With IID_IDispatch
.Data1 = &H20400
.Data4(0) = &HC0S '&HC0S
.Data4(7) = &H46S '&H46S
End With
With Pic
.Size = Len(Pic)
.Type = 1 'PicTypeBitmap
.hBmp = hBitmap
.hPal = hPalette
End With
MsgBox(Pic.Size)
MsgBox(IID_IDispatch.GetType.ToString)
' Create Picture object
r = OleCreatePictureIndirect(Pic, IID_IDispatch, True, IPic)
'Return the new picture
CreateBitmapPicture = IPic
End Function
I have read some posts stating that the OleCreatePictureIndirect has changed in .NET but as I have no .NET experience and no reference material, the detail given in the solutions is lost on me.
Could someone please explain in relatively plain english the situation and the solution???
Could you also recommend some good reference material for getting up to peed with .NET
Any help greatly appreciated
Cheers

Hello world 
I've written an app that employs disconnected data via datasets. I had a situation lately where a user modified over 10 records (out of a total of 25 contained within my dataset). When the user tried to update the datasource with their changes some of those records violated database rules. The user then had to manually scroll thru the dataset SEQUENTIALLY to see which records caused the update to fail. How do I modify the app so that in such a situation it automatically displays the first record that causes the update to fail?
If it is any help, the app was built using the Data Form Wizard in VB.NET.

I have a suggestion that u might wanna look at,
what you can do is to highlight those records that caused the problems and let user rectify.
BTW : I am curious, how can u let user update fields that can cause DB error? wanna leave an example here?
thx

You're thinking along the same lines as me. However, the question is, how does one determine which records are the rogues? For example, if we are sending 5 records back to the datasource but one has caused a concurrency violation, how do we know which one has caused the violation? 
As for your question I think it's just a case of highlighting the field (on the data-entry form) that caused the error, allowing the user to correct the data, then allowing them to save the data again (via the appropriate command button on your form).

I just received a call to debug a TAPI problem.
The company that created the control no longer exists.
Problem: When the VB App finished making a call and downloading via modem, it closes the program without giving a reason. This only occurs on machines running Win2000 or WinXP. The program was origanaly written and tested on Win2000 (also tested on Win3.1, Win95 and Win98).
Could this have something to do with Windows security updates?
Any ideas would be helpfull.

Hi there,
I'm trying to create a DAL. Therefore I'm analyzing the DotNetNuke project and extracting code to create my own DAL. Thusfar I managed to talk to the database (with DataProvider.Instance). Now I'm trying to use a FillObject method, but I seem to be stuck at this point. I'm getting the following error 'System.Reflection.TargetException: Object does not match target type'. The error occurs in the sub CreateObject (last catch) at the following line 'CType(objProperties(intProperty), PropertyInfo).SetValue(objObject, Null.SetNull(CType(objProperties(intProperty), PropertyInfo)), Nothing)'. I was trying to isolate the problem (in sub Testing), but I can't figure out what's going wrong. I'm new to this stuff (that is working with a DAL, filling objects automatically) and I'm not an DotNet expert. Could someone explain to me what's going wrong? Does it have anything to do with trying to fill a wrong instance? Here's my code:

My VB6 program can't find referenced dll unless it located under windows directory.
What should I do in order that my VB app will search for referenced dll in local directory first?
|
|
|
|
|
Can you post the way you use the dlls?
Because when referencing a dll, OS first looks in the SAME directory that your application is running, then looks in the system folders.
