OK, now I get what you're talking about. Saving a GIF with transparency is not as easy as it should be. Read this[^].

Hi!
I had got in a situation of creating a Crystal Report dynamically without creating a .RPT file externally.
Is there any way by which i can give the report fields dynamically and make the connection within the codes of VB.net 2005.
Thanks!

|
|
Yes, You can do it by using .xlt and .xls
|
|

I did not realise that this was possible with Crystal, and will not investigate, as it will resolve a problem I have.
Thanks

Hi,
I had a problem that I want to pass one or more data from one application to another. For example I have two application named "Application_1" & "Application_2"
Application_1 is already running in my system.
When I open the Application_2 it has to send the information like its name & time to the application_1.
How can I do this in VB.net(Windows application) Please anyone help for me to solve the above problem.
AdVance Thanks,
Karthiyayini.

WM_COPYDATA, named pipes, writing data to a commonly known temp folder, will all work.
Of course, this assumes that you are writing both apps.

Hi everybody,
I am using a Sockets.NetworkStream to request approval or denial from another machine, but I do not want to sit and wait for it indefinitely. Could anybody offer some guide?
This is the code I am using:
....
Dim iMsg() As Byte
Dim Stream As Net.Sockets.NetworkStream
Dim iTPC As New Net.Sockets.TcpClient()
MgrIp = Get_UpdloadApprovIP()
If MgrIp = "" Then
Msg("No manager's available to service this request!", 16, "Cannot Proceed!") : Return
Else
iMsg = System.Text.Encoding.ASCII.GetBytes(sClerk & "|" & MyIp & "|")
'//sClerk & MyIp are local variables
iTPC.Connect(MgrIp, 10002)
Stream = iTPC.GetStream
Stream.Write(iMsg, 0, iMsg.Length)
ReDim iMsg(1) '//honestly can't remember why I am doing this
Stream.Read(iMsg, 0, iMsg.Length)
iTPC.Close()
iMsgStr = System.Text.Encoding.ASCII.GetString(iMsg)
If CType(iMsgStr, Short) = 1 Then
UploadFrm.ShowDialog()
Else
Msg("Your request to upload your data has been denied!", 16, "Cannot Proceed!")
End If
End If
....
Thanks for your time and help 
Alex.

You're not going to be able to do this with such simple code. The answer is to use the Asynchronous version of the Read method. This is goign to result in MUCH more code than you're got here. For a few examples, Google for "VB.NET TCP Server".

Thank you Mr. Kreskowiak for your guide.

HI...
How to save and restore values in multi textbox,Datetime picker,combo box when the form close using vb.net !?
I found the source code for saving values of single textbox in external file generated by the form.
Unfortunately because I’m newbie in vb.net I couldn’t make it work with multi textboxes??
----------------------------------------------------
the code for single textbox:
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
If IO.File.Exists(Application.StartupPath & "\save") = True Then Kill(Application.StartupPath & "\save")
Dim Read As String = textbox1.Text
FileOpen(1, Application.StartupPath & "\save", OpenMode.Binary)
FilePut(1, Read, -1)
FileClose()
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not IO.File.Exists(Application.StartupPath & "\save") Then Exit Sub
Dim Read As String = Space(FileLen(Application.StartupPath & "\save"))
FileOpen(1, Application.StartupPath & "\save", OpenMode.Binary)
FileGet(1, Read, -1)
FileClose()
textbox1.Text= Read
End Sub
---------------------------------------------------------------
My Q.How to save the values if we have many textbox or many datetime picker when the form close??
Regards...

I used application settings to store things like the path to where my reports are stored. My development file structure is different from my production file structure.
Here is a snippet of code for loading a string ...
Me.tbox_rptPath.Text = My.Settings.rptPath.ToString
You will find these settings by clicking on your "My Project" in your solution explorer, then click on the tab called, "Settings". Define whatever property you desire to store the selected values in the combo boxes, etc.
My property is called, "rptPath" in the above example.

I need to develop a process to import a Lotus 123 spreadsheet into SQL Server. Has anybody out there ever used .NET to work with Lotus 123 files? I haven't been able to find a way to access the files through a datasource. Does anybody know how to start?
Thanks

Thank JZ, but will that work for Lotus 1-2-3 spreadsheets or is that only for the Lotus Note email database?
|
|
|
|
|
Oooh, I'm not sure. I think I've only done the database with it.
|
|
|
|
|
According to Microsoft's KB[^] article, there should be a Lotus 1-2-3 ODBC driver available via a 3rd party (such as directly from IBM or whoever owns Lotus).
|
|
|
|
|
Having no experience with Lotus at all myself, I found a few apps on the web that can convert a Lotus 123 spreadsheet to xml.
Perhaps you could look into first doing a conversion to xml, from which you can then easily import into any database.
I personally have done the same with excel files.
for what it is worth...

My advice is free, and you may get what you paid for.

Thanks to everybody who answered my question. After doing some research, and not coming up with much, I decided to convert the Lotus 1-2-3 file to an excel spreadsheet as a first step. It's a manual process now, but I'm pretty sure I can automate it. I opted for excel because then I can use a reference to Microsoft Excel 9.0 Object Library and easily work with workbooks, worksheets, ranges, etc. It makes the rest of my work easier. Maybe not the optimal solution, but it seemed more practical than engineering to work with Lotus given the time schedule.
Thanks!

I'm Parsing ATOM Feeds using File.ReadAllText and RegEx isolate item nodes. Some Atom feeds work just fine, others return "no content" (even though I've verified through a reader that "item" content exists).
It appears that the feed is blocking the content ...I'm having a synaptic mis-fire isolating the problem. I can't locate any documentation on this issue.
Someone point me in the right direction?

i use VisualBasic 6 Enterprise and want to configure the visual source safe
i have installed all the latest service pack releases untill service pack 6
but i keep on getting this error
Corrupt 'um.dat' file
Please help me...i need to share some source files with my manager
Thanks

Hi,
To resolve this problem, build a new Um.dat file. Note that when you build a new Um.dat file, you must add all of the users again.
1. To build a new Um.dat file, follow these steps: 1. Create a temporary folder named C:\Sstemp.
2. Click Start, click Run, type cmd, and then click OK.
3. Go to the VSS\Win32 folder in the command prompt window, and then type the following command:
mkss c:\sstemp
4. In the VSS\Win32 folder at the command prompt, type the following command:
ddconv c:\sstemp
5. In the VSS\Win32 folder at the command prompt, type the following command:
ddupd c:\sstemp
6. Copy the Um.dat file from the C:\SStemp\Data folder to the Visual SourceSafe data directory.
7. Rename the Rights.dat file in the Visual SourceSafe data directory as Rights2.dat.
8. At a command prompt, run the analyze -f command against the database.
9. Add all of the Visual SourceSafe users again.
10. Reassign rights to the Visual SourceSafe users.
This should fix the issue : ).
