A datagrid works only with a DataSet and you should bind this to a DataGrid.

how can i use mshflexgrid in vb.net
i have add it from com lib but it is not working like visual basic
asdf
|
|
|
|
|
DataBinding goes like this:
Dim objDataSet As New DataSet()
objCommand.Fill(objDataSet)
myDataGrid.DataSource = objDataSet.Tables(0).DefaultView
myDataGrid.VirtualItemCount = GetVirtualItemCount()
myDataGrid.DataBind()
|

|
|
|
Update DataSet and bind the DataGrid

If I have a jpg file like 1024*768,
but my picturebox only has 800*600,
How can I make the jpg file scale(zoom) to fix the picture box to show?
Thank You!

Sorry for that, I know this property ...
What I really what to know is like a zoom function in All reader,
when we press the (+), the picture zoom in; (-), the picture zoom out.
Thanks anyway.

Change the SizeMode property of PictureBox to StretchImage.

As the title,
I would like to use ghostScript in VB.NET.
I am going to read render PDF in VB.NET or convert it to JPG.
Any reference or article for this purpose.
Thanks a lot.

First you need to set the printer to one that can either
generate Postscript, or to something like RedMon that can directly
output to Ghostscript.
Second, you need to script Word to print.

Dim fs As FileStream
fs = File.Open(myFile.FileName, FileMode.Open, FileAccess.Read)
the file exists in the client pc, but it cannot find the file to upload,any idea on how to solve this? thanks in advance

I assume this is only for use on a local network ? And you're passing through a full network path ?

thanks for the reply,
i am using a HtmlInputFile, to upload the file from the client, what things should i take care of if this is not just for local network use?

Your best bet is to write a webservice that you can tunnel your files to.

Hello everyone,
This is my first time using hashes so I'm not all that sure if what I need can be done or is a good thing to do. I'm making a (salted) hash of a unique identifier that will be included in the query string of a link. When the link is followed, I want the page it hits to get that hash value and de-hash it because it contains information that I need for a database query.
All the tutorials I've found show me how to hash data but not unhash it. Can anyone point me in the right direction?
Thanks in advance for your help!

You can't de-hash a hash code. Hashing is not encryption.
The size of the hash code is limited, but the number of strings that can be hashed is virtually unlimited. That means that there are a lot of strings that gives the same hash code. It's impossible to tell which of the strings created the hash code.

Ah, I that makes sense. I'll just figure out some other way to do it without using the hash, then.
Thanks!

Well I can't really help you there. It's up to you to research which control will work best for you and your project.
These forums are really for specific coding questions. If you just want to learn about Crystal Reports in general, then your best bet is to read some articles and/or read a book. Crystal Reports is by no means a small topic.

MS Access requires a DateTime SQL string to have US formatting, even when running your app in other countries. You also need to surround it with # symbols.
I recommend that you add a conversion function like this...
Public Function DateTimeToSql(ByVal dtValue As Date) As String
Return dtValue.ToString("\#MM\/dd\/yyyy HH\:mm\:ss\#")
End Function
Then convert the DateTime to a SQL string like this...
Dim query As String
query = "insert into Dt (Date, Val) values (" & _
DateTimeToSql(Date.Now) & " ,3)"
|
|
|
|
|
Oops. I just noticed that you wanted just a date, not a date-time. In that case, use a function like this...
Public Function DateToSql(ByVal dtValue As Date) As String
Return dtValue.ToString("\#MM\/dd\/yyyy\#")
End Function
