I'm in the middle of coding a very very basic application for my coursework and I need to use a drop down box. VB isn't my favorite subject, but I do the best with what I know (which isn't a lot, hence why I need help :P). I'm currently trying to use a combo box to link pages together. I'm using if statements like this;
[Code]...
The program runs fine, but when I try to press the button to go to the page I've selected, I get the yellow box around my code and it says 'Conversion from string "Bronze" to type 'Boolean' is not valid.'
I really don't have a clue what that means. To me, what I've written as code should work. I have an 'enter' button to which this code is attached to, so when the combo box says 'bronze' and you press the button, it should close this page and take me to the bronze page. But it won't work and it's stressing me out now.
My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?
I'm trying to have it so that when the user selects an item from the combo box, it will display the right nodes for that selection in the treeview control. For example: User selects Artist from the combo box and the treeview displays the letter of the artist. The user selects a letter and it will display all artist with last names beginning with that letter. Unfortunately when I select a selectedindex, the treeview doesn't display anyting, it's blank. What am I doing wrong? Here's the code I'm using for artists:
I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer Pages = New Integer() {1, 3} PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:
I have heard of setting server specs to have HTML pages parsed as PHP pages by changing the .htaccess or httpd.conf files. Is there a similar solution to have HTML pages parsed as ASPX pages?
A website I am working on does not want their PageRank to lower since their HTML pages are already indexed and used on other websites but wants to use some dynamic features of aspx pages (like include the navigation file so that changes to the nav will only have to be done in that one file).
i have this program which records the every printing made on a local computer.I am to record the number of pages of the document to be printed and the number of printed pages. i have this code but i don't know the number of pages and number printed pages always return 0 [Code].
I'm using visual basic 2010 express..I'm building my own web browser and want to add a download manager.I have been able to build one that will download a file if I type the file location into a text box.What I'm trying to figure out is how to have the download manager open when I click on a download link on a web page.How to make the download manager know it is a link to a downloadable file as opposed to something like a link to another webpage?
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.
When a button is clicked i am creating HTML that will be displayed in the WebBrowser1 control. With this HTML are several links to other pages. Is it possible that when one of these links is clicked, that WebBrowser2 navigates to the page instead of WebBrowser1?
I have a project that I would like to add a URL link and an email link to in the Help/About dialog. How can I do this? Is it possible to add HTML code to a VB project? This is not a Web application.
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' fills the combo boxes with values Me.xGeneralComboBox.Items.Add("Soda") Me.xGeneralComboBox.Items.Add("Juice")
How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.
I am getting an error when i try to populate some combo boxes with a value, the combo box has values in and the right amount the code is getting the right number.
the error msg is "Object reference not set to an instance of an object."
Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.
Private Sub cboCategory_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCategory.LostFocus
I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

I have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?

so I'm using Visual Studio 2010 and I'm trying to make a program where I would have a textbox where the user would type,then a "Go" button. In the textbox, the user would type a number, lets go with 1 for an example. A user would type 1 in the textbox, then it would automatically add the 1 to the end of this .swf link: "http:[url]... after they enter the 1 in the textbox and press the "Go" button, it would add the 1 to the end of that link, then that link would open a new shockwaveflash form with the link being the Movie. Is this possible?
I have a program developed in VB.NET (2008) which consists of a MDI form and several child forms. It worked like a normal mdi application whereby mdi form acted like a container for child forms and things worked out okay. Code like Me.Mdichildren or Me.ActiveMdiChild etc could be used to get list of child forms etc.
Now what happened is I needed to implement a tabbed system. There will be multiple tabs and forms would be in those tabs. So I added a Tab control in mdi form and now new forms are added to selected tab page. This way muliple tab pages can host forms and there is no need to see all childforms at once.But a problem has come up. I do say ChildForm.MdiParent = Me (as before) but then I say TabPage1.Controls.Add(ChildForm). Doing so functions like list of mdi children or me.activemdichild or auto arrange options like Cascade,Tile Horizontal, Vertical etc are not working.

I'm developing a program in vb.net, and I want to add in some help pages to the program, without using web-based help, so more like when you hit F1 in the Microsoft Office programs. Is there a straightforward way of doing this, other than just making it via lots of forms?
