How do I reset the active directory to the directory where I started the program from without using relative or absolute paths? Is it possible? Thanks in advance 
edit: The reason I need this is that I use openfiledialogs and savefiledialogs which changes the current directory, and I have stored help files relative to the program path.

There is a property on the Dialogbox which you can specify to restore the location to the original value.

Set...
myOpenFileDialog.RestoreDirectory = True<br />
mySaveFileDialog.RestoreDirectory = True
This will prevent the app's current directory from changing and allow these dialogs to still remember the last selected path.

It sounds like you are accessing your help files via relative paths. If so, then I strongly recommend that you access them via absolute paths, which can be built based on Application.StartupPath.
The reason is if someone makes a shortcut to your app but forgets to set the working directory to the app's path, this will break all of the relative paths to your files.

You should not be worrying about what the current directory is. You should be using absolute paths ALWAYS when dealing with files. You can always get the applications directory by using:
Dim appDirectory As String = Application.StartupPath
You can make a fully qualified path name by using something like this:
Imports System.Io
.
.
.
Dim myHelpFilePath As String = Path.Combine(Application.StartupPath, "myHelpFile.hlp")

:-OHi - I have installed Visual Studio.net 2003 and it is working well with a few irratating exceptions that I cant solve - the books asume this knowledge so I I'm stuck.
First problem - in debug mode hovering the curser over a varable name in older versions gave the VALUE of the varable, in my setup I get a definition of the varable which is of no interest to me - how do I change the setup to get actual runtime values?
Second - There is no Draw toolbox - I have all the controls etc but I cant draw a line or a circle etc on a form - where is this hiding (its not in the available tools from the add dropdown).
H e l p! (please )

You don't change anything. You're getting the definition because the code either was not stopped (hit the pause button next to the run button), or your code was stopped and your trying to get the value of a variable that is no in scope. You code was stopped in one method (Sub or Function) and you're looking at a variable in another method.

It's not hiding anywhere. There are no such tools. You're expected to either draw these things yourself in code or use a PictureBox or some other control to load an image file.

Hi,
Do you know how to get path to the CD drive? If there are two CD drives, and you have inserted a CD to a drive, how do you get path to that correct drive
Thank You,
Chatura

I also want to know the answer.
I know the follow code.
System.Environment.GetLogicalDrives()
Useing this code I'll get the all drives letters. But It does not provide which is CD drive and which is hard drive.
If you found the solution. Share me your solution.
Have a nice day.

 ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) Thanks for your reply. When I was surfing the internet, I found some interesting tips.
Although they were in VB6 format, I converted them into VB.Net format and combined them together.
This program has,
A label “lblCDDrives”
Tow buttons “btnClose” & “btnOpen”
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer<br />
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Integer<br />
<br />
Private Const DRIVE_CDROM As Short = 5<br />
Const ASC_A As Short = 65<br />
Const ASC_Z As Integer = ASC_A + 25<br />
<br />
' Return the CD-ROM drive letters.<br />
Private Function SearchCDDrives() As String<br />
Dim i As Short<br />
<br />
For i = ASC_A To ASC_Z<br />
If GetDriveType(Chr(i) & ":\") = DRIVE_CDROM Then<br />
SearchCDDrives = SearchCDDrives & " " & Chr(i)<br />
End If<br />
Next i<br />
End Function<br />
<br />
Private Sub btnClose_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles btnClose.Click<br />
'Close CD Door<br />
mciSendString("Set CDAudio Door Closed Wait", CStr(0), 0, 0)<br />
End Sub<br />
<br />
Private Sub btnOpen_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles btnOpen.Click<br />
'Open CD Door<br />
mciSendString("Set CDAudio Door Open Wait", CStr(0), 0, 0)<br />
End Sub<br />
<br />
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
lblCDDrives.Text = "CD drives are: "<br />
lblCDDrives.Text = lblCDDrives.Text & SearchCDDrives()<br />
End Sub

Hi
I have a form with 7 Datagrids. I populate DataTables from a database. I create a Dataview of the tables, and apply various filters based on user selections. I then use the DataVeiw as the Datagrid DataSource. I have also used Tablestyles to give the Datagrid Columns 'Readable' columnnames, and have adjusted the width of certain columns and set the columnwidth to 0 on some columns in order to hide them. This all works great.
Now I want to add the option to Export what displayed by the datgrids to Excel.
This is easy with a Datatable, since I can use the Column Names as headings, and then use a loop
For Each Col as Datacoumn in dtMyTable.Columns<br />
<br />
For each Row as datarow in dtMyTable.Rows<br />
cells(Row,Col) = ...<br />
Next 'Row<br />
<br />
Next 'Col
I'm battling to get the datagrid back into a table format - and cannot Ctype(Datagrid, DataTable) directly.
Any ideas how I can do this. (I'd like to be able to use the column headings and column widths of the datagrid to format the Excel sheet)
Thanx
Richard

I wish I knew an answer. I've been watching this message since you posted it, hoping someone would have the answer. I've ran into the same problem recently. If you figure out how I hope you'll followup and let me know what you find. Thanks

Have you tried:
Dim dSource As Object
dSource = DataGrid.DataSource
If TypeOf dSource Is DataView Then
Dim tbl As DataTable = CType(DataGrid.DataSource, DataView).Table
'Export to Excel...
End If

Hi Dean
Thanks 4 your reply. That works, but the problem is that I have a table with 6000 records. This Table is that datasource for a DataView. I then apply filters to the dataview. (So for example now the Dataview only has 100 Records) It is these 100 records that I want to put in a new table for export.
Using your method, it returns the full source table with all 6000 records.
I'd be happy to loop through the Dataview and adding those rows to a table, but can't seem to get that right.
Richard

You can pull data directly from the dataview which would allow you to only use the filtered data:
Dim i As Integer = 0
Dim dr As DataRowView
For Each dr In MydataView
ExcelWs.Cells(i, 1).Value = dr("Field1")
ExcelWs.Cells(i, 2).Value = dr("Field2")
.........
ExcelWs.Cells(i, n).Value = dr("Fieldn")
etc
i += 1
Next

Hello,
u will have to make a setup project u can add setup project as:

- Select Project type as "Setup and Deployment Wizard"
- Select Setup Wizard From Template
- A wizard will ask u some questions just complete it
- Now u have to add merge modules for crystal report which u can add as?
* Right Click on the Setup Project
* Add --> Merge Modules
* Select Following
** Crystal_Database_Access2003.msm
** Crystal_Database_Access2003_enu.msm
** Crystal_regwiz2003.msm
** VC_User_CRT71_RTL_X86_---.msm
** VC_User_STL71_RTL_X86_---.msm
- Build the solution
- A setup will be created in Setup Project Folders's -->Debug
- Copy it and run it on client machine

You need to register with Crystal Reports first. Then in your setup directory include the proper DLLs as mentioned in CR's documentations.
