I'm creating a component in VB.NET which acts as kind of a wrapper for Ms Outlook 2003 and Ms Word 2003. There are three components which can be used seperately. Now when I want to use the Outlook component, I don't want to load the Word assemblies and vice versa, but I dot want the controls within a single assembly.
Is it possibly to create the references to the required Office Interop Assemblies at runtime (in the constructors for example) so when loading my assembly, not needed office resources will be left alone?
For example, when using the Outlook control, my assembly loads Office.Core.dll and Office.Outlook.dll and NOT Office.Word.dll
I love it when a plan comes together

Did you try using classes in the System.Reflection[^] namespace? They allow you to load assemblies at runtime, which is exactly what you want to do.

The previous reply hits it on the head, but be warned that if you use Word as the Outlook email editor, it will load Word components regardless.

I was hoping to be able to use multiple selection upon a dropdownlist but the only info i have found is related to a dropdownlist in a datagrid. Is it possible then just to add the multiple selection to a dropdownlist the same way as when using the datagrid. thank you

Dropdownlists are meant to allow user to select a single value. What you could do is cheat a little bit by displaying a ListBox on top of your combobox. To do that, capture the combobox dropdown event then call SuspendLayout of combobox, place dropdownlist on top, and call ResumeLayout of your combobox. When user is done selecting, hide the listbox.

Hi, I am tejaswi and having a small doubt in VB regarding the collections class.
The following code Is not working
Dim temp as new clsParameterDetail
Dim objcoll as new collection
Temp.initializeobj()
Objcoll.add( temp)
Where as if I declare it as an array ( dim temp() as new clsParameterDetail )
And after redimensioning and initializing the temp array,
It is accepting the statement (Objcoll.add(temp) )
What is the difference between an array and normal object. In case of a single object the .add is not working( giving a message like ‘property or method is not supported’) where as in case array it is accepting.
It is not even accepting sth like objcoll.add(temp(parameterCount))
but it is accepting for strings even if it is not an array .
Please clarify my count.
And one more thing is – Is CType(obj,TypeName) a function available in visulbasic or only .net ? if in vb any references to be added , this function is not available here in vb here.here if i type vba. ,all are coking like cstr e.t.c but ctype i snot coming.

I am designing a windows app in vb.net. There I added a imagelist control which contains some alphablended images. When I try to debug it it shows an error
"An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
Additional information: Exception has been thrown by the target of an invocation."
pointing the line
" Me.ImageList1.ImageStream = CType(resources.GetObject("ImageList1.ImageStream"), System.Windows.Forms.ImageListStreamer)".
But while there was no images in Imagelist control nothing happened.
What is the wrong with it? What should I do now?
Thank you in advance.

I'm using HelpProvider to display a chm file on the users machine. When I view the properties of the HelpProvider, I want to specify the location of the chm file in HelpNameSpace. The chm file is written to the users application file. By default (i.e., provided the user doesn't change the install location), I know where the chm file will be (e.g., C:/Program Files/[program folder]/[filename].chm)so I can specify it in HelpNameSpace. But what if the user chooses not to install in the default location? I was hoping that the browser for HelpNameSpace would be similar to the Icon browser and would let me specify a file saved in the target application folder... but it doesn't. Can someone help?

Can't you use the Application's StartupPath property and set the path to the CHM file at runtime?
System.Windows.Forms.Application.StartupPath

Hmmm... looks promising! So you're suggesting I query for Application.StartupPath and append the path to the file name of the CHMs in the application folder?
Thank you very much!

First I'd like to say that I've been trying to find a solution for 2 days from many resources. The code runs but only the first item in the listbox is being killed.
My textfile = "list.txt"
Contents of list.txt
notepad
wordpad
Here is a snipit of the main section of my code.
<br />
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
'Opens File Specified as .txt only<br />
Dim openFile As New System.Windows.Forms.OpenFileDialog<br />
openFile.DefaultExt = "txt"<br />
openFile.Filter = "Text documents (*.txt)|*.txt"<br />
openFile.ShowDialog()<br />
If openFile.FileNames.Length > 0 Then<br />
Dim filename As String<br />
For Each filename In openFile.FileNames<br />
' Displays path of text file to listBox1<br />
ListBox1.Items.Add(filename)<br />
'Displays content of selected text file to listBox2<br />
Dim file As New System.IO.StreamReader(filename)<br />
Dim oneLine As String<br />
oneLine = file.ReadLine()<br />
While (oneLine <> "")<br />
ListBox2.Items.Add(oneLine)<br />
oneLine = file.ReadLine()<br />
End While<br />
file.Close()<br />
Next<br />
End If<br />
End Sub<br />
Public Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click<br />
'Checks to check if items in listbox2 are selected<br />
Dim n As String<br />
n = ListBox2.Text<br />
If n = "" Then MsgBox("No Process Selected!", MsgBoxStyle.Information, "Process Not Selected")<br />
'Compares items in textbox2 against running processes, if found it kills it<br />
Dim lined As String<br />
Dim proc() As Process<br />
Dim i As Integer<br />
Dim prokill As Boolean<br />
lined = (ListBox2.Text)<br />
proc = Diagnostics.Process.GetProcesses<br />
For i = 0 To proc.Length - 1<br />
If proc(i).ProcessName = lined Then<br />
Try<br />
proc(i).Kill()<br />
prokill = True<br />
Catch ex As Exception<br />
Exit Sub<br />
End Try<br />
End If<br />
Next i<br />
<br />
'removes killed processes from listbox2<br />
ListBox2.Items.Remove(ListBox2.Text)<br />
ListBox2.SelectedIndex = -1<br />
'ListBox2.Items.Clear()<br />
End Sub<br />
I've tried adding listbox2.text to a database, but my research and small amount of experience leave me with a headache for 2 days... any help or guidance would be greatly appreiciated. Thanks.

You need to replace the code that takes the text from the listbox, and replace it with code which iterates through the Items property, using foreach. Then you can process each one. I'd create a KillProcess method, and call it from the loop, just to factor out the code a little.

I'm not sure how I would go about that. I appologize, I started learning about 4 days ago. I've had to research each section of my program and this is what I've been stuck at for 2 days. If you could maybe start me off where I need to go with it. I can run it through my head, but of course that's not how it works.. lol. Thanks again Christian...

Something like this:
Dim lined As String<br />
<br />
For Each lined In ListBox1.Items<br />
proc = Diagnostics.Process.GetProcesses<br />
For i = 0 To proc.Length - 1<br />
If proc(i).ProcessName = lined Then<br />
Try<br />
proc(i).Kill()<br />
prokill = True<br />
Catch ex As Exception<br />
Exit Sub<br />
End Try<br />
End If<br />
<br />
Next<br />
Next

Well I swear I tried something similar... anyhow, I thank you again! Another simple solution to a silly problem. Thanks.

Glad to help. I have to admit, I did not test this, but there's no reason I can see for it not to work. I typed it into the IDE, so the code itself is valid and should be correct. It's certainly how it's done, even if there's some change needed to make it work.

By the way... YES! It worked perfectly...

Can anyone point me at a data bindable print document thing?
I am prepared to write this if it doesn't exist, but it's a big job so I don't want to waste time reinventing someone's wheel.
What I am looking for is a component that allows you to design a rudimentary document and then data bind to it at run time. Simple stuff: labels, paragraphs, images. (possible graphs and graphics at a later date)
Any ideas?
If such a thing does not exist any ideas as to what it should contain?

Seems to run twice?
My code is fine if a button onclick event is used to start the sub I want but if the sub is called from the combobox onchange its a bit screwed up as it runs it twice seemingly simultaniously.
Does anyone know is there's a way to remove the control and add it back with lostfocus events?

Try using SelectedIndexChanged intead of onchange.
You must be careful while using onchange.
onchange will fire when the text in combo changes or if the selection changes.

Hi
Thanks for that, I should have been more clear I am using that event handler but still no luck. Thanks anyway,
