Hello,
I am trying to get my program to open an external program. I also plan to make this portable, so I made a folder for my program to go to.
It's like this: Click OpenOffice and my program manager will go to:
Vegrard Suite\Vergard\OpenOffice\program\soffice.exe
This folder is located in the root directory of the program; wherever this root directory is in will make the program read the folder that's in its root directory.
The problem, however, is that I can't get the program to launch without going to a fixed location on the C drive "C:\Users\User\My Documents\Visual Studio 2010\Projects\Vergard Suite\Vergard\OpenOffice\program\soffice.exe". The idea is that wherever you put the application folder (Vergard Suite) , the program will always refer to the folder that the application is in to open the program (Vergard Suite\Vergard\); therefore, it can be made portable (like Windows 3.11: wherever the WINDOWS directory is located, Windows will go to the program's folder that was specified).
How do I get this to work???

Your question doesn't make a lot of sense. It may be obvious to you but the description is missing some critical detail.
Why would OpenOffice be under your Projects folder?
There are two paths to be aware of when launching an application. The first is the fully qualified path to the executable you're trying to launch. What this path contains is entirely dependent on when the application is installed. How are you getting this path?
The second is the "Startup Directory". This is what the current path should be when the target application is launched. Normally, this path doesn't matter at all, but some apps do require it. How are you going to determine if the app requires this and how are you going to determine what this path is?
There are the "well-known" paths that Windows supplies. Using the Environment.GetFolderPath() method will return the path of certain folders using an enumeration value to determine which folder you want the path for. See the documentation for GetFolderPath()[^] and SpecialFolder enumeration[^] for more information.

This is what I mean:
Say you want to launch a program called "Banana" through the program manager. The program manager is located on your desktop. The program manager will check inside its folders, not the entire C: drive for that particular PC, for this program, and finds it at:
\Vergard\Banana\Banana.exe
The program will then launch Banana.exe from \Vergard\Banana\Banana.exe, not C:\Users\Me\Desktop\Vergard Suite\Vergard\Banana\Banana.exe.
Now say that you copy Vergard Suite to your flash drive. You go to your friend's computer and try to launch your program through the program manager. What's supposed to happen is Vergard will go to \Vergard\Banana\Banana.exe, not C:\Users\Me\Desktop\Vergard Suite\Vergard\Banana\Banana.exe. This can be proven effective if it works. It's like that command in batch scripts: ".\Vergard\Banana\Banana.exe".
How can I get it so that my program mananger will execute a command similar to the bstch command to open that file, no matter where the program manager's files are?
Oh, about the OpenOffice: I put it in the Projects folder to test the program manager's ability to OpenOffice.

You still have to build a complete path to the .EXE, not a relative one. This is because the relative path would be relative to whatever the "current directory" is and that can change without your code knowing it.
Since the folder is under your program files folder, you can get the path to your own .EXE by using Application.StartupPath. You can then build the remaining path to the target .EXE using the methods in the Path class[^].

|
|
|
|
I just realized this... Is it possible to have my application run that bstch script command? I know people have made CMD redirects before, so theoretically, it should work, right?
|
|
|
|
|
What "bstch" command? There's no such thing in Windows and any script lanugage I know of.
|
|
|
|
|
Oops... I meant batch script.

|

Yes, you can run a batch script using the Process class.

Open a command window. Type "Path".
Those are the folders that Windows searches if you do not specify a location. If it ain't in there, it won't be found, unless you specify a full path.

I have a CommonDialog that uploads a picture (jpeg) and then saves it to a specific file. It works fine in Windows XP, but not in Windows 7. I have it open in My Computer and then save to a remote temp file. The prblem is that Windows 7 gives you the last location you either viewed or saved to and not the folder that you hard coded into the VB6 program. Is there a way around this? Is there a way to turn the option off in Windows 7 or a different Dialog to use in VB6?
Here's my Code:
Public Sub subUploadImage()
Dim stFromFile As String
Dim stToFile As String
Dim inCnt As Integer
st_MYCOMPUTER_CLSID = "::" & "{20D04FE0-3AEA-1069-A2D8-08002B30309D}"
stPath_Ols_Photo_Temp = "i:\programs\old\photo_temp\"
On Error GoTo ErrorHandler
frmSubjectMaint.CommonDialog1.InitDir = st_MYCOMPUTER_CLSID
If frmSubjectMaint.CommonDialog1.Flags = cdlCancel Then
Exit Sub
End If
frmSubjectMaint.CommonDialog1.Filter = "JPEG Files (*.jpg)|*.jpg"
frmSubjectMaint.CommonDialog1.FileName = ""
frmSubjectMaint.CommonDialog1.Flags = cdlOFNHideReadOnly + cdlOFNOverwritePrompt
frmSubjectMaint.CommonDialog1.ShowOpen
stFromFile = frmSubjectMaint.CommonDialog1.FileName
frmSubjectMaint.CommonDialog1.InitDir = stPath_Ols_Photo_Temp
' frmSubjectMaint.CommonDialog1.InitDir = stPath_Ols_Photo
frmSubjectMaint.CommonDialog1.Filter = "JPEG Files (*.jpg)|*.jpg"
frmSubjectMaint.CommonDialog1.FileName = mskSsn.Text
stToFile = frmSubjectMaint.CommonDialog1.FileName & ".jpg"
frmSubjectMaint.CommonDialog1.ShowSave
FileCopy stFromFile, stPath_Ols_Photo_Temp & stToFile
' FileCopy stFromFile, stPath_Ols_Photo & stToFile
If Dir(stPath_Ols_Photo_Temp & stToFile) <> "" Then
If Dir(stPath_Ols_Photo & stToFile) = "" Then
FileCopy stPath_Ols_Photo_Temp & stToFile, stPath_Ols_Photo & stToFile
Else
inCnt = 1
If Dir(stPath_Ols_Photo & stToFile & ".old" & inCnt) = "" Then
Name stPath_Ols_Photo & stToFile As stPath_Ols_Photo & stToFile & ".old" & inCnt
Else
Do While Dir(stPath_Ols_Photo & stToFile & ".old" & inCnt) <> ""
inCnt = inCnt + 1
Loop
Name stPath_Ols_Photo & stToFile As stPath_Ols_Photo & stToFile & ".old" & inCnt
End If
FileCopy stPath_Ols_Photo_Temp & stToFile, stPath_Ols_Photo & stToFile
End If
Kill stPath_Ols_Photo_Temp & stToFile
End If
frmSubjectMaint.lblNoPhoto.Caption = ""
frmSubjectMaint.imgPhoto.Picture = LoadPicture(stPath_Ols_Photo & stToFile)
Exit Sub
ErrorHandler:
Select Case Err.Number
Case 52
Call subErrorRoutine("There is no disk in the specified drive. Do you want to upload from a floppy diskette?.", 4)
If inUserResponse = vbYes Then
Resume
Else
frmSubjectMaint.CommonDialog1.InitDir = st_MYCOMPUTER_CLSID
Resume Next
End If
Case 58
'Already on file
Resume Next
End Select
End Sub

You could use the VB.NET OpenFileDialog; there was a toolpack aimed at those who have to migrate from VB6 to VB.NET, that also showed how to call .NET code from VB6.
Alternatively, you could build one from scratch.

We aren't using VB.NET for this. Otherwise we would just convert the entire program to VB.NET. How would you suggest I "build one from scratch".

I know; the suggestion would be to extend your application using some other language than VB6.

The same way any form is built in VB6. That's what the dialog is, just another form with textboxes and buttons.
You're welcome btw

When an row in a ListBox is selected, it is highlighted a nice deep blue.
If that ListBox loses focus, the ListBox's selected row remains highlighted in blue.
However, when a ListView loses focus (and it's HideSelection property is set to false), although the selected rows remain highlighted, the highlight is no longer a nice deep blue but rather a barely visible light grey.
Is there a way to change the highlighted color of ListView's selected row when the ListView no longer has focus?
Thanks,
Jim Dolson

The control is using the system colors to paint itself.
If you want to change the colors it's using, you'll have to paint the control yourself. C# Custom Paint ListView[^]

In addition to Dave's answer, it's usually not worth the effort. Unless you use the highlight-color as defined in the system-colors, your blue would default to red on my desktop
If it's merely to get consistency then do consider the fact that you are adding code that might throw exceptions/have bugs, while the only advantage is color-consistency (one that is still a non-default, and hence, unexpected)
If you are letting the user make a selection, then you could consider using checkboxes to indicate the selection.

Thank you gentlemen. I've decided to leave the default behavior alone.

Hello !
I'm using Vb.net 2013 , Entity Framework , SQL Server 2008R2 and SMO.
I want to disconnect from database and set offline.
I try this code using SMO:
conn = New ServerConnection()
conn.ServerInstance = serverName
srv = New Server(conn)
Dim db As Database
db = srv.Databases(databaseName)
db.setoffline
But the problem is that the application hang on the last line and doesn't respond.
Is there anything that I should do with entity framework before set the database offline ?
Thank you !

You can't use EF to offline a database. You have to use the normal SqlCommand and SqlConnection objects to execute the query yourself.

Hi Everyone,
I have used below code do open word document from a VB Application with OLEWord control, While opening it below error message is displayed.
"Open Database Connectivity Error" and details below description displayed.
"ODBC Error: [[Microsoft][ODBC Driver Manager] Data Source name not found and no default driver specified
SQL State: IM002
Return Code: SQL_ERROR"
Note:
1. Error occurs randomly.
2. after clicking OK to the Error Message word opening properly.
Code and Images attached.
Kindly help me regarding this issue.
Code:
Dim mWordDoc As Word.Document
Set Data.Recordset = Rx_db.OpenRecordset("SELECT reg_object FROM REGISTER WHERE reg_id = " & vRegId)
If Not Data.Recordset.EOF Then
Data.UpdateControls
If OLEWord.OLEType = vbOLEEmbedded Then
Set mWordDoc = OLEWord.object
If Left(UCase(OLEWord.Class), 13) = "WORD.DOCUMENT" Then
Set mWordDoc = New Word.Document
OLEWord.DoVerb vbOLEOpen
End If
End If
End If
Data.Recordset.Close

Check your connection-string; it's not related to Word, it's related to the query.

Thanks for your reply.
My connection string like below
"ODBC;DSN=SampleDSN;;UID=SampleId;PWD=sample;"
The error says default driver missing where can we set default driver for specified ODBC connection

I am trying to mirror a VB frame to RightToLeft direction. I succeeded to mirror the frame, but all the text of frame components(Labels and text box) are mirrored too.
Is there any way to prevent the components to be mirror?
Const WS_EX_LAYOUTRTL = &H400000
Const WS_EX_NOINHERITLAYOUT = &H100000
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
Get
Dim CP As System.Windows.Forms.CreateParams = MyBase.CreateParams
If Not MyBase.DesignMode() Then
CP.ExStyle = CP.ExStyle Or WS_EX_LAYOUTRTL
End If
Return CP
End Get
End Property
When I tried to add "OR WS_EX_NOINHERITLAYOUT " the frame didn't mirror at all.

I did tried to populate my usercontrols to 3000 times and my form crashed.
