No I don't, Like I said in the last message, I haven't used the shimgvw.dll
It looks like a lot of folks are looking for Info on it, when I seached on google, but the functions are undocumented so without a lot of work it may be quite difficult to decode all that it can do. Just playing with it, I got VS to generate a wrapper, but it doesn't wrap the IPreview3 functions.
I did come across a microsoft post about it, on how to use it under the shell but it's not much:
'-------------------------------------
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
'Process.Start("c:\windows\explorer.exe", "C:\drums.jpg")
Process.Start("c:\windows\system32\rundll32.exe",
"C:\WINDOWS\System32\shimgvw.dll,ImageView_Fullscreen c:\drums.jpg")
End Sub
Please Apply My Suggestion Above And Let Me Know If It Helps Resolve Your
Problem.
Best regards,

Sorry I can't help you out more, But I'm in the middle of a large project now, when I have time, I'll try to check out some more of the functions.
In the meantime if you come across any documentation that would be of interest drop me a note.

Hi Group,
I need an Urgent Help.
I have been connecting my application to a remote mysql database(For development it is in lan only).
I fail to retrieve data from database
I have used this:
<br />
if rs.eof then<br />
rs.movefirst ' have also used rs.movelast<br />
else<br />
rs.movelast<br />
endif<br />
but it does not help.......
Tell me how to rectify it....
Thanks
Amit

you also need to check for rs.bof. If the recordset is empty (no rows returned) BOTH eof and bof will be true, and movefirst, movelast, movenext, moveprevious and move(bmk) will all return an error, sice there is no record to move to.

Can anyone tell me the code to select a datagrid row. Getting mixed up and any help would be greatly appreciated.
Example
Have the following rows in a datagrid.
EmpID Employee Department
1 Jones Accounts
2 Smith Sales
3 Green Sales
4 Ross Accounts
I want to select say emp ID 2.
What properties do I have to use to display
2, Smith and Sales onto 3 seperate variables.
I think it is something to do with the datagrid click but cannot work out how to assign the column values to a variable.
|
|
|
|
|
Worked it out. It is as follows
datagrid.Item(datagrid.CurrentRowIndex, 0)
|
|
|
|
|
datagrid1.tables(0).rows(2)

Use the Select method of the DataGrid.

 i need help with vb.net code for forward and back navigational buttons for a picturebox.the picturebox loads images and their associated text(the text files contain titles and refence nos.for the images) from a folder.their are actually two pairs.One forward and back pair of buttons is for navigating previously selected(loaded) images.the other pair of forward and back is for navigating the filed images startin from the currently selected image.
Also need code for searching for the images using their reference numbers or title.

I take it you haven't written any code for this yet? Break the problem down into simpler parts. You have to maintain two lists of images for navigation. One list will be the "previously loaded" list. The other, the list of files in a particular directory. This is easy using an ArrayList. The buttons for forward and backward would just increment and decrement an index value pointing at the currently in-use indexes into those two arrays.

You must be mistaking us for RentACoder. We don't get paid to write code for other people here. We will help you with your code, not write it for you.

besides pics my proj loads text(title and ref. no.)from textfiles in the folder containing the pics.the proj is supposed to search for pics using the title and ref no.i can only get it to search title(first line in the text file).any tips on how u can search for the ref no.

Maybe you should post your some sample code and a sample of the text file you are working with. Otherwise, it defeats the purpose of asking for help here.

this is the code for the open button(for opening the images and text files in the folder).
Imports System.IO
Public Class Form3
Inherits System.Windows.Forms.Form
Dim y As Integer = 0
Dim z As Integer = 0
Dim w As Integer = 0
Dim c As Integer = 0
Structure Imagefile
Public image As Bitmap
Public title As String
Dim text As String
End Structure
Dim x(16) As Imagefile
Private Sub MnuFileOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
With OpenFileDialog1
With OpenFileDialog1
.Title = "choose a picture to display"
.ShowDialog()
PictureBox1.Image = Image.FromFile(.FileName)
End With
End With
Dim textfilename As String
textfilename = OpenFileDialog1.FileName
textfilename = StrReverse(textfilename)
textfilename = textfilename.Remove(0, 4)
If textfilename.StartsWith(".") Then
textfilename = textfilename.Remove(0, 1)
End If
textfilename = StrReverse(textfilename)
textfilename = textfilename & ".txt"
Dim fs As StreamReader
fs = File.OpenText(textfilename)
Richtextbox1.Text = fs.ReadToEnd
With x(c)
.image = PictureBox1.Image
End With
With x(y)
.text = Richtextbox1.Text
End With
c += 1
y += 1
End Sub

I'm having a problem understanding how to register Windows Shell extensions, specifically for PropertySheet extensions and their handlers.
I am not too happy with the way it's done here -
http://www.codeproject.com/cs/miscctrl/HadiPropertySheet.asp
- "Property Sheet Shell Extension in C#"
I think this can be done with PInvoke, rather than RegAsm.exe. Obviosuly, the batch file for putting the keys and appropriate GUID into the registry can be done in code (and would be less error-prone).
Also, can anyone direct me to an example in VB.NET for the same sort of thing that's described in that article? That is, a property sheet extension example.
Thanks for any help - Ian Thomas

You COULD code your own RegAsm to do this, but why reinvent the wheel?
RegAsm is used to register the assembly, it's classes and methods, with COM so the Shell knows where and how to get at the functions it needs to call when a Property page goes up. Since the .DLL needs some external application to kick off any of it's functions, including registration, how do you expect to get the .DLL regsitered without using an external program to do it, like RegAsm or an .MSI installer?

Registration-less activation IS possible, but it's only supported in Windows XP SP2 and Windows 2003.
Read up on it here[^].

Hi,
I want to open calendar view for multiple recipients in the same
window.
The view has to be called from .net, when we select more than one person
it has to display the calendar of those two persons in the same outlook
window.
(i.e. How we are creating recipients object for creation of new appointment
or mail like that)
olRecpts = appointmentItem.Recipients()
olRecpt = olRecpts.Add("santosh")
olRecpt = olRecpts.Add("tim")
olRecpt = olRecpts.Add("mark")
olRecpt = olRecpts.Add("rambabu")
' this is for distribution list
oDistList = myOut.CreateItem(OlItemType.olDistributionListItem)
oDistList.Addmembers(olRecpt)
The above code is for creation of new Appointmnet, mail for multiple
recipients.
In the same way i want to view the calendar of more than one person.
Can any one help me regarding this problem.
Regards,
Santosh.

I don't think you can do that because of the outlook security but in case I'm wrong and you don't get a response here on CP, There is an Outlook forum here, with a vb.net section:

The play list configuration allows the user to generate as many play list as possible.Each play list is a series of contents which plays one after another. A play list is an xml file that contains the list of files to play.The system shall also allow the operator to preview the play list and allow him to 'fast forward'. The following contents are supported:
- scrolling text with different properties
- powerpoint slide show.
- images, logos , photos,animations..
- Video ( MPEG1,MPEG2,AVI,Quicktime movie,Real video,Microsoft Windows video...)
Thanks for guidance.
