Custom ComBobox With Headers - Prevent Selection Of Headers?
Dec 15, 2009
I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.
Header 1
Item 1_1
Item 1_2
[code]....
I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.
1_1 1_2 1_3 2_1 2_2 2_3

how to add the row headers to the Datagridview? We can normally add Column headers from the Properties. But there is no option for Row headers. Can we add them through the IDE? Or we need to do it dynamically?

I want to number the rows in my datagridview. Basically the users want to know how many rows they have posted, so they can stop at a certain number.So I have done several web searches all giving the solution I came to on my own, but still nothing is showing! it's almost like there is a property I need to set to show text in the row header, otherwise it's somehow disabled or not visible, but I am not sure what!!!

Private Function Base64_Encode(strSource) As String
Const BASE64_TABLE As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"

I am using a webbrowser control and loading a website that uses basic authentication. I pass the username and password in the additional header of the navigate routine. The problem is that the header is not retained while navigating the site.
I.E.I log into the site and pass the user name and password in the http header. When I click a link to access another page the header is removed and the site asks for credentials. If I was to just type the site into IE and log in the first time the headers are carried forward on all pages. how I can have the page retain the headers so the user never has to authenticate?
Dim sHeaders As String
Dim HelpBrowser As New WebBrowser
sHeaders = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("UserName:Password")) & Chr(13) & Chr(10)
Me.HelpBrowser.Navigate("http://www.mysite.com", True, Nothing, sHeaders)

I'm writing a mail component for a VB.Net app, and need to handle mails differently that are "Sent on Behalf" of someone. Although the Outlook Object Model exposes "SentOnBehalfOfName", it doesn't expose the email address for that party. Supposedly it's in the "OtherHeaders" field of the SMTP header, but I don't see an easy way to get to those through the Mailitem object. Am I missing something simple?

What I'm trying to achieve is something similar to an Add-on called Live Http Headers used with Firefox. I'm not trying to get the Headers or cookies, but the links that load on the page itself. Let us assume I visited Mail.Yahoo.com, this is pretty much what you would see when I use the add-on.
CLICK HERE How can I achieve something similar ? Only the links that load on the page itself.

I have a csv file that is being sent to me in this format[code]...
This is the only way this file can be exported from the system that is sending the information.
The second item is the Header and of course the 3rd would be the value that needs to be inserted into the row. How do I import a file like this. It is going to be sent to me every 5 minutes so I have to be able to extract the data shortly after the file arrives and insert it into Sql server.

What I'm trying to do is parse a CSV file that has column headers, and map those headers - ideally to a class.The tricky part is that I need to be able to support various mappings because it will be interacting with different systems that give the headers different names. Additionally, being able to combine fields would be extremely helpful.
Fortunately, the CSV will always be correctly formatted with all fields encapsulated in double quotes.

I am currently working on a personal project with hopes of using VB.NET 2008 to connect to my personal forum for use of both authentications into the program and group changes. People in my forum are based on ranks, the ranks are organized via the groups in the forum so if one person gains a rank they need to be taken out of one group and placed into another. With multiple people this is a process and presents a security risk should someone get kicked out but accidently be left in a group giving them access.
For the time being, I need to be able to post the headers to the forum to login and parse the response. I have tried many times and I�m currently trying this using the chilkat dll as a reference which allows me to send headers and see the response, but the response is always the failure to login page. The headers are as follows:

I use a datagridview where the rowheaders frustratingly stay blank after I load the form. If I modify/add/delete anything the rowheaders pop up. then when I sort by clicking on a columnheader the rowheaders become blank again. all these actions (load/add/modify/sort) go through the same refresh function. I can't seem to figure out why the rowheaders sporadically show up. they should stay visible all the time. btw, datagridview.refresh() doesn't work
