Stop Two Users From Clicking One Link?
Feb 16, 2010
I have an website that has a datagrid that is pulling information from an SQL database. The user then clicks a link from that grid and is redirected to another page. My question is if a user clicks the first link and is redirected and then a second user clicks the link is there a way to stop that second user from being redirected or sent back to the first page after they click the link? So it would have to somehow detect on the second page that a second user has clicked the same link. Hope this is clear. This is being programmed in VS 2008 vb.net and SQL 2008

I have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
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?

First, let me clarify that the links call on javascript/jquery functions. The href="#" for ALL links and can not/will not be changed (it's not even my website that I'm grabbing it from). There is no name or id for the <a> tags, so I'll be needing to InvokeMember("click") on the link based on the text that is between the <a></a> tags.
For example:
<a staticrndstuff="stone" customrndstuff="waffles" href="#">TextForTheLink</a>
I've tried every method I could find on google and even consulted /g/ to no avail. The 'staticrndstuff' is the same for all links, but the 'customrndstuff' is unique to specific text/links. Usually, for something with an id you can simply use WebBrowser1.document.GetElementById("ElementID").InvokeMember("click"),
But how can I have a vb.net forms application click a link on a webpage based on the text between the <a></a> tags or on the static/customrndstuff?
This is the hardest thing I've encountered, which is a bit sad for me.

I can now navigate to pages, fill forms, submit forms, click elements etc.My next big step will be collecting html element ID's which are constantly different each time I navigate to a page.On the webpage I am working on, each page contains 10 of these ID's.
ill_btn_20234518
ill_btn_20534538
ill_btn_20174048
Now I am just looking to click on one of them at random for right now. It doesn't matter which one. Or perhaps the first one to appear on the webpage.Here is the code that I tried first........it works fine for clicking static buttons (without the random id #'s at the end)
Dim ill As HtmlElement = WebBrowser1.Document.GetElementById("ill_btn_")
ill.InvokeMember("click")
End Sub
I guess what I am looking for here is some sort of partial id tag, to let it know to search for the first ID that begins with ill_btn_ ?

I have an application where the admin user can create users and upload documents to the server for the created user to download.
When uploading a file it creates a folder using the userid as the folder name and saves in that folder within a folder called documents e.g. ~documents/77b29079-43d6-4520-bc34-77ae2af1b131/documentname.xls
The client then has to login and will see a list of available documents for that user only. The only problem is that if someone was to get hold of one of the urls to a document is can be downloaded without having to login.
Is there something I can do to stop access to these files?? I have tried editing the web.config file to only allow access to certain roles but i could still download a document without logging in.
<location path="documents">
<system.web>
<authorization>

how to stop a ComboBox from displaying blank data?
The query I'm using does not allow nulls but the ComboBox is showing black areas and the user can click in those areas.
The PureComponents ComboBox did not show the blank areas but when I started to use the ComboBox from VS 2008 the blank areas are showing up.
The attachment shows me clicking in a blank area.

I have a VB 20008 Express project which currently uses a DLL. I would rather distribute a single .EXE
I used DLL2lib and converted it to a library, but as I haven't done this before,
How can remove the DLL from my project? The Project menu has an "Add resource" option, but I can't find any way to remove it (it doesn't show up in Project/Properties). Do I simply remove the Imports statements from my code? How do I statically link to the library?

I currently have some security working in my application by using the roles and rules, but i wondered whether it was possible to hide web links depending on if a user belongs to a certain role.I currently have it so users belong to either the 'admin' role or 'user' role. Rules have been setup on folders in my application so if a user belongs to either of the groups they can click on a web link and it takes them to the page. However, if a new user registers they belong to no role, and when they click on the web link it redirects them to the homepage (see code below). This is great, but, i wondered is it possible to hide that web link if the user did not belong to a specific role preventing them click on it. Also if a user belonged to no role could they be redirected to a page to tell them they need a role assigned?
<authentication mode="Forms">
<forms loginUrl="~/Homepage1.aspx" timeout="2880" />
</authentication>
I dont use this in the current application but have in the past, this checks if the user has been authenticated, i wondered whether i could use a similar IF statement for:If user.identity does not belong to 'user' or 'admin' role, then redirect them to page and display error?
If User.Identity.IsAuthenticated = True Then
Dim myUser As MembershipUser
Dim objUser As Object[code].....

I have a form that allows users to enter information into a few textboxes. When users click save, the information will be transferred into the datagridview.
My problem now is, for instance, there is a textbox called "Price" with the datatype "money" which users are only allowed to enter numbers. If users enter alphabets, errors will occur. I don't wanna use try catch, I would like to try different methods such stopping users from entering anything into the textbox when the datatype isn't correct - nothing will appear in the textbox when users hit all the keys in the keyboard except for numbers.

I'm new to visual basic & have learned many new things in such a short period of time from being on the MSDN forums. I have learned particularly in the subject of automating web browsing control using the getattributes etc., but I have tried everything that I have seen in the forums to auto click the "Settings" link in a created gmail account and then have the browser automate the "Forwarding" to another gmail address. I haven't found a solution anywhere to accomplish this.
So here is an account to try out in which this should only take a few mins to a veteran coder:

When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?
Friend Sub CloseAllForms()
CloseHelpForm(True)

Someone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available.

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.
