but it only populates the first selected manuf, and doesnt change after
Private Sub selCurrentManuf_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles selCurrentManuf.SelectedIndexChanged

View 6 Repliesbasically i'm making a webbrowser, and i want it to select and option from a dropdown ComboBox, on a certain button click. I use this code which i found it on these forums as well:
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("select")
If element.GetAttribute("id") = "wrapper_opacity"
element.SetAttribute("value", "51")[code].....
The problem with this code is that it just inputs the selected value, but it doesn't really SELECT it.The option selected is shown, but not activated.
I created a Windows Form application that used a Webrowser control to automate the process of entering data into a website. One of the tasks included selecting a server name from a dropdown menu (SELECT tag). I was able to get a collection of all of the OPTION tags and use HTMLElement.SetAttribute("selectedIndex","indexVal ue") to select the server I needed.The website recently went through a redesign and now there are no OPTION tags. It appears that the values for the SELECT tags are added by JavaScript dynamically. I have tried using HTMLElement.SetAttribute("selectedIndex","indexVal ue") directly, but I am unable to select what I need.

So I've made a program in VB 2010, and it has three comboboxes and a button to view. Now lets say my first combobox is "Type of website". The options are "search engines", "social networking" and "news". The second combobox values would depend on what the first combobox value is selected, like if it was "news" the options would be "technology", "uk", "us", and "world".
The third combobox would then use the values in the first and second comboboxes to give even more values, for example if it was "news" and "technology" the values would be "engadget" etc. Then the view button would open the selected website in an internet browser. How would I code this?
I am new to vb.net and I have looked at other topics. I cannot find the answer I need. OK I have a combobox named cboRaceDesc and five checkboxes (CkRaceAfricanAmerican, ChkRaceAmerican Indian, ckRaceAsian, ckRacePacificIslander, and ckRaceWhite). I was going to post an image, but I cannot.cboRaceDesc has two options...Hispanic and Other. If the user selects Other then they have to choose one of the five checkboxes or it will raise an exception when the record is being saved. I am assuming I would generate the code under the "save" button. I know I need to gather the following information in my code:
If cboRaceDesc.SelectedValue = Other Then
<I am not sure how to code the logic regarding the checkboxes>
<I know I need to use multiple else/else if statements>
<I know towards the end I would generate the exception>
End
Can anyone help me fill in the blanks or point me in the right direction?
I really like the coding speed that vb.net provides, but I don't like the possibility to forget to declare variable types, return types of functions, etc. and that is why in each class I use[code]..
Is there a way to define those two options on the project/solution level?
the combo box style 1 has both the drop down option but also a manual entry option. I need to know how to code it so that when you manually enter data, it takes that data and places it in a text message "The shipping charges for "data" is $15" displaying in a text box. Shouldn't be hard but have developed a mind block.

1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.
2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]
I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.
I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far
Public Class Main
Private Sub NewToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripButton.Click, NewToolStripMenuItem.Click[code]....
I know I have some finishing touches such as messages and error handling and stuff but at the moment I want to get all the basics working,I think the save menu option is all I am struggling with at the moment.
Using VS2008, targetting framework 3.5, trying to update some VB4 code. Yes, VB4.I have a bunch of legacy code I'm trying to update, and I had the idea of trying to work through it by executing the old code, working out what was causing each error as I came to it, solving the problem, and then moving on.In order to do this, I have sinned and set Option Strict Off, Option Explicit Off and Option Infer On.Yes, I'm going to hell for this.Problem is, I'm still getthing errors that various things haven't been declared.All of these the items showing errors are in the form: itemName(obj)Is my problem that the compiler thinks that these are method calls for methods which haven't been declared?PS: For anyone wanting to tell me not to use these settings, I already know
View 2 RepliesI have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

I have installed WCF / WPF Extension with Visual studio 2005.
I developed the sample WCF services and to consume it I have developed the client project.
In client project I need to give the service reference, however I noticed here Add service reference option is missing.
I would like to make the option available that my program can be changed in another language.
A simple solution would be a checkbox on my form which you can click on to change to language X or Y.
Does anyone have the code for this or can point me in the right direction ?
I've seen that there are several options out there for being able to send email from within a Visual Basic program, but I've seen much less written about how to use the program to receive emails. What I'd like to do is set up a dedicated email account (probably g-mail or Yahoo or something similar, although it could be through the email package that comes with my web hosting) that I'd use to send short text commands to the program from my laptop or smart phone. Periodically the program would download new emails (if any), and parse the body to see what I'm telling it to do. Something like, "cmd a" tells it to e-mail me Report A, "cmd b" tells it to e-mail me Report B, etc.

Late binding is not allowed and that's how we want it. Depending on whether our program is running on a LAN or the Internet, we need to dim an object as one of two types. We use an if...then statement to ascertain whether or not we are running on a LAN or the Internet.
When we declare our object inside the if...then statement, we have declared in the wrong scope and cannot use the object. When we declare it as an 'Object' type and use DirectCast inside an if...then statement, we receive a late binding error. How can we get around this problem without turning off Option Strict?
I do not live in USA, and my program run specifically with my country's Regional and Language Option format. However, many Windows XP, Vista and 7 installed in my client computers automatically with English (United States) Regional and Language option. I want my program to automatically change the computer regional and language option to my country. However, I do not find anyway to do that (changing the computer regional and language option in runtime by the program), yet.
