hello, how can i add a SWF file to a form without importing it as a picture
|
|
|
|
|
You'll have to add a Reference to the Flash Player COM control, add it to the ToolBox, then drop one on your form. I'm not really familiar with it past that though.

First off, we don't support third party controls here. Considering there's thousands of them out there, it's impossible for us to know every single one.
Second, you haven't supplied any of your code showing what your doing (or not doing). Without that, there's little we can do to help you.

How to dynamically add tab and picture control as a pair?
I tried something like the following. but it didn't show
each picture control on each tab.
For i = 1 To 5
Load Picture1(i)
Load TabStrip1(i)
Picture1(i).Visible = True
Picture1(i).Left = Picture1(i).Left + 100
tab
Next i
how can i achieve this.
I am using vb6

My VB6 is pretty rusty, but here goes...
Load only loads forms, not controls. What you have to do is create a new instance of the control you want, then add it to the Controls collection of the form/control you want to host the new control.
In your case, you want to make a new Tab, not a TabStrip, add it to the TabStrip's Tabs collection.
Dim newTab As New Tab
newTab.Name = "Tab3"
newTab.Caption = "My New Tab"
TabStrip1.Tabs.Add(newTab)
Adding the PictureBox control is done just about the same way.
Dim newPicBox As New PictureBox
newPicBox.Width = ...
newPicBox.Height = ...
newPicBox.Left = ...
newPicBox.Top = ...
newPicBox.Name = "PictureBox3"
Form1.Controls.Add(newPicBox)

I am working on a web application project where i need to uplaod many pdf/doc files onto the webserver and download those files when the user clicks the corresponding hyperlink.
I used the following code to upload the file, where MyFile is the html file input control.
If Not MyFile.PostedFile Is Nothing And MyFile.PostedFile.ContentLength > 0 Then
Dim fn As String = System.IO.Path.GetFileName(MyFile.PostedFile.FileName)
Dim SaveLocation As String = Server.MapPath("Articles") & "\" & fn
Try
MyFile.PostedFile.SaveAs(SaveLocation)
Response.Write("The file has been uploaded.")
Catch Exc As Exception
Response.Write("Error: " & Exc.Message)
End Try
Else
Response.Write("Please select a file to upload.")
End If
but it doesn't write it on the server( i need to load this onto my school's web sever.)
How do i download this file? If possible, how can i disable the save button on the pdf fiels when the user downloads the file.
I am using asp.net and vb.net , if anybody can help me write a code to this project it will highly appreciated.

Your question really belongs in the ASP.NET[^] Forum. It doesn't have anything to do with VB, even though your wrote in VB.
Also, you haven't supplied any error messages or exceptions that are thrown. The most common things to check is if the servers ASPNET account (or whatever account your application is running under) has the permissions to write a file to whatever path your trying to save this file to. By default, it doesn't have this permission.

Well, the Font property is read/writable. But, once created, the Font is immutable. You can't modify it. What you have to do is create a new Font object and assign it to the ListBox.Font property. But, you can create a new Font by using an existing one and modifying the parameters as you do so:
ListBox1.Font = New Font(ListBox1.Font, ListBox1.Font.Style Or FontStyle.Bold)

Not through properties. It's all or nothing. The only way to do it is if you were to owner-draw the control. This will give you the ability to draw each item individually, and in the process, change its font.
Search the articles for "custom listview" and you'll find examples of owner-drawing the ListView control.

I just need to know how to find the "Type of File" property that is found when you right click on a file in WinXP. There is a line in the properties window that reads "Type of File" and then reads the application that uses that file, like Adobe Acrobat Document, or Microsoft Word Document. I'm using the Dsofile from microsoft to determine the author, title and etc, but i don't see anything pertaining to the "Type of File". I also know how to determine the extension of a file using the FileInfo. Any ideas? thanks!

SHGFI_TYPENAME
Retrieve the string that describes the file's type. The string is copied to the szTypeName member of the structure specified in psfi.
=============================================
Something like this:
=============================================
Imports System.Runtime.InteropServices
Public Class Form1
Inherits System.Windows.Forms.Form
Private Declare Auto Function SHGetFileInfo Lib "shell32.dll" ( _
ByVal pszPath As String, _
ByVal dwFileAttributes As Integer, _
ByRef psfi As SHFILEINFO, _
ByVal cbFileInfo As Integer, _
ByVal uFlags As Integer _
) As IntPtr
<structlayout(layoutkind.sequential, charset:="CharSet.Auto)"> _
Private Structure SHFILEINFO
Public hIcon As Int32
Public iIcon As Int32
Public dwAttributes As Int32
<marshalas(unmanagedtype.byvaltstr, sizeconst:="260)"> _
Public szDisplayName As String
<marshalas(unmanagedtype.byvaltstr, sizeconst:="80)"> _
Public szTypeName As String
End Structure
Private Const SHGFI_TYPENAME As Int32 = &H400
Private Sub Form1_Load( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs _
) Handles MyBase.Load
Dim x As SHFILEINFO
Call SHGetFileInfo("C:\test\test.tex", 0, x, Len(x), SHGFI_TYPENAME)
MsgBox(x.szTypeName)
End Sub
End Class

Here it is again with the right structs:
Imports System.Runtime.InteropServices
Public Class Form1
Inherits System.Windows.Forms.Form
Private Declare Auto Function SHGetFileInfo Lib "shell32.dll" ( _
ByVal pszPath As String, _
ByVal dwFileAttributes As Integer, _
ByRef psfi As SHFILEINFO, _
ByVal cbFileInfo As Integer, _
ByVal uFlags As Integer _
) As IntPtr
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Auto)> _
Private Structure SHFILEINFO
Public hIcon As Int32
Public iIcon As Int32
Public dwAttributes As Int32
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=260)> _
Public szDisplayName As String
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=80)> _
Public szTypeName As String
End Structure
Private Const SHGFI_TYPENAME As Int32 = &H400
Private Sub Form1_Load( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs _
) Handles MyBase.Load
Dim x As SHFILEINFO
Call SHGetFileInfo("C:\test_tl\ausarb.tex", 0, x, Len(x), SHGFI_TYPENAME)
MsgBox(x.szTypeName)
End Sub
End Class

I need a bit of help. I'm trying to enumerate the windows PATH environment variable so that each directory listed in the PATH variable can be extracted and displayed/edited/messed with individually.
I can retreive the path no problem, and i could probably parse the string and store the results in a collection, to achieve this, but that seems a bit cumbersome.
basically i'm trying to see if a file exist in any of the directories listed in the PATH variable. So i'd like to be able to do something like this.
For each path in winpath
If File.Exists(PATH & "\file.nam") Then
bExists = True
End If
Next
or something like that.
anyone know the easiest way this can be accomplished?

RePost, I messed up the first one
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Debug.WriteLine(SearchFileInDirTree("c:\test\", "TestText.txt"))
'File is realy in folder "c:\test\test1\test2\"
End Sub
<System.Runtime.InteropServices.DllImport("imagehlp.dll")> Shared Function _
SearchTreeForFile(ByVal rootPath As String, ByVal inputPathName As String, _
ByVal outputPathBuffer As System.Text.StringBuilder) As Boolean
End Function
Function SearchFileInDirTree(ByVal rootDir As String, ByVal fileName As String) _
As String
Dim buffer As New System.Text.StringBuilder(260)
SearchTreeForFile(rootDir, fileName, buffer)
Return buffer.ToString()
End Function
|
|
|
|
|
That function looks like this:
<System.Runtime.InteropServices.DllImport("imagehlp.dll")> Shared Function _
SearchTreeForFile(ByVal rootPath As String, ByVal inputPathName As String, _
ByVal outputPathBuffer As System.Text.StringBuilder) As Boolean
End Function

Does anyone have an example of how to pass integers through a TCP client.
I am trying to pass 32bit integers without success.
I don't seem to be able to convert Int32 to bytes
I can pass strings without problems
Any help would be appreciated

It took awhile to realize I was going way down the wrong road. I finally found an article by Ken Spencer that made all the balls drop into place 
It's funny how a simple twist of a phrase can make such a big difference.

I am now wrapping the the first version of my app and looking forward to additional enhancements.
Hello all, I am trying to get a grip on data access coding. I have a several text boxes that access the address fields of my row. I was trying to get away from lots of add/delete/update buttons on the form. So.., I would like be able to add a new address when the user changes the selection on a combobox (assuming an existing record does not already exist).
My question is two fold.
One. The code sample below is currently errors with the following:
Additional information: Cannot bind to property or column Address on DataSource.
When adding (resetting) the binding to my textbox.
Two. Am I even using the correct approach to peform this maintenance.
I seems that .net doc is volumous too say the least.
Some assumptions here. lb Lenders is a listbox that is the master for this detail form
cboAddressType relates to the validation table of ...addresstypes.
Thank you for any guidance regarding this.

I want to write a VB.net code for a software that will capture fingerprints from a biometric scanner.It will serve as an access control system which gives access to a network resources such as files.The software will enroll users fingerprints and store them in a dbase(SQL).It will also gives access when a match is found in dbase when a user scan his/her fingerprint and it denies access if such users fingerprints are not found.It will also keep time and attendance record and should be able 2 generate such reports.This is my final year project @university.I need help in form of codes,advice,tutorials or whatever will achieve this task 4 me.Thx.
