Allow write access for the user that the website is running as to the directory you are trying to write to.

I think that you have to provide more information.
Where are you trying to upload the file? To your own application?
Is the error message generated by the application, or are there any more information in the error message?
Is this a VB application, or would this question be better off in some web development related forum, like ASP.NET or Web Development?

Hey All!,
Ia have a project iam currently working on in VB.Net. Its about a travel company that provides world wide flight routes for travellers. It as proposed that each traveller will be represanted by a linked list.
Now my aim is to produce a prototype of a software to demostrate to the travell company by designing, implementing and testing a linked list class and this class must include the properties and methods : Forward link, Node text add/insert node and remove node. Then implement a procedure that will traverse a linked list generating a graphical represantation of a linked list using label controls.
How can i solve this problem, PLEASE HELP!

What is it that you have a problem with, then?

b { font-weight: normal; }

If you search the articles here you wil find 10's of results showing linked list implementations.
If you expanded the same search to Google that number would probably be 1000's

Original String:
Ki KiE:สวัสดีค่ะ โปรแกรม โอเอ็มเอส โดย บริษัท เอ็มเอสแอล ซอฟต์แวร์
Problems Facing:
1. The missing '00' in the begining and trailing part of the generated string
2. The white spaces within the original string (in THAI) show up junk characters instead of SPACE.
Please check this by pasting the source code attached and help me out in generating Correct output.
thanks in advance.
Correct Output which i am expecting to generate

Some XP user use the XP form style, some of them disable the style to use the classic one.
However, this style really affect the look of my form.
How can I know what is this setting in user computer?
|
|
|
|
|
You can P/Invoke UxTheme.dll which controls the window styles in XP like this...
<DllImport("UxTheme.dll", _
CallingConvention:=CallingConvention.Winapi, _
CharSet:=CharSet.Auto)> _
Private Shared Function IsThemeActive() As Boolean
End FunctionIf this function returns true, the user is running a theme, if it returns false then the user is running 'Windows Classic Style' - no themes.
Hope this helps
Cheers,

Thank you so much and It is really a great hint for me,
but it does not work by copy and paste.
Where should I place it in my module ?
Thank you~
|
|
|
|
|
To add it to a module you'll have to do two things...
1) Change the line
Private Shared Function IsThemeActive() As Boolean to
Public Function IsThemeActive() As Boolean (i.e. remove the word Shared and change the functions visibility to Public)
2) Add
Imports System.Runtime.InteropServices to the top of your file.
I havent done any VB.Net in a while so I hope that works
Cheers,
Will H

hi, i would like to insert a picture,(logo) of da company as a background and insert button ENTER on that.but i dont know how,sir, could u pls help me on doing that..thanx a lot.

You can specify a BackgroundImage for a form and place your buttons and other controls on the form as normal.
Other things that might be better for what you want are placing a PictureBox on the form with the logo in it. To make sure it stays behind the other controls, from the Format menu, choose Order > Send to back.
Or, place a Panel control on the form and set the Background image of it to your logo. You can then place controls on the Panel control itself (panels are container controls)
Hope that helps!
