Winforms Web Browser Control Not Firing Document Complete With AJAX Website
Mar 18, 2010
The VB.Net desktop app uses the IE browser control to navigate the web. When a normal page loads the document_complete event fires and I can read the resulting page and go from there. The issue I am having is that the page I am driving is written with AJAX, so the document complete event never fires. Furthermore, when you view the source of the page after it loaded a new portion via AJAX, it hasn't change.

I'm currently working on a reporting app that saves a report to HTML, then sends it to a PDF printer.First off, to render the HTML I am using a webBrowser control:
Dim _renderer As New System.Windows.Forms.WebBrowser
To print the HTML document, I am using the WebBrowser.Print() function
_renderer.Print()

In a page to create new user accounts, we have a database with a little of allowable users. To streamline getting the Email address of the new user correct, we want to use an AutoComplete extended textbox.Now I know that WebMethods are working because I have a cascading-drop-down tied to web methods in another page.As I'm just starting on this page, the code is simple.The page itself:
<cc1:ToolkitScriptManager ID="ScriptManager2" runat="server"/>
<p></p> Please enter new user's Email:
<asp:TextBox ID="txtUser" runat="server" />
<cc1:AutoCompleteExtender runat="server" ID="autUser" TargetControlID="txtUser"
[code]....
I'm not even getting to the LogDebug statement. I've used all the same boilerplate code (Inherits, the 'WebService' tags, etc) that worked in the other WebMethod with the appropriate changes to the Class name but this really has me stumped.

In my app I am using a web browser control, I am displaying a list of files that are there in selected Directory, when the file type is of some image I do it as WebBrowser1.Navigate(sFileName), the image is then displayed in the Web Browser Control, when there is Word Doc I had code that converts the word doc to HTML and it is displayed in the WB Control all good so far, now when the file is of type xls, xlsx I am not converting the file to HTML instead I just use the navigate command and open the file in Excel so that user can then edit it and save it on his system. Now the problem is lets say I am toggling through pages in Directory first file is Image so it will be displayed next when it is Excel file then it will open the file in MS Excel but the WebBrowser COntrol has that previously opened image, I want to clear that when the excel file is opened. So here is what I tried. [code]It navigates to Excel file but does not display text and the image from previous file persists in the web browser control.I even tried to navigate it to "about:blank" but it then does not navigate to Excel file.

I'm trying to use an ajax auto complete extender, but it's not working. I put a break point on the GetCompanyNames method in the web service, but it doesn't even hit the break point.
Here is my ajax autoextender
<asp:TextBox TabIndex="1" ToolTip="* Required - enter the Company name" ID="txtCompanyName"
runat="server"></asp:TextBox>
<ajaxToolkit:AutoCompleteExtender runat="server" ID="acCompanyName" TargetControlID="txtCompanyName" ServiceMethod="GetCompanyNames" ServicePath="~/WebServices/AutoComplete.asmx" MinimumPrefixLength="1"

I'm trying to tie the AJAX autocomplete control to a textbox and pull the results from an sql database using VB. Anyone know how to do this? I found plenty of examples in c but I need to do it in VB. Here's code for C I guess but I can't figure out how to convert it to VB.
[WebMethod]
public string[] GetCountryInfo(string prefixText)

Using ASP.NET 3.5 with VB codebehind.
I don't want to use a webservice to populate an autocomplete extender on a textbox. In this case, it's where the user is entering email addresses and I don't want to make a trip to the database every single time. I'd much rather keep a collection in session state and 'bind' the autocomplete to that.
Is it possible to set ServicePath and/or ServiceMethod to something in the codebehind as opposed to a webservice?

The following code populates a second dropdown when the first dropdown changes (i.e. cascading dropdowns). However, the Ajax call isn't firing, and I can't figure out why. I'm not getting any syntax or runtime errors. When in debug mode, the GetPlans action is never being called. The inner alert is never called, but the outer one is. To make matters worse, this same setup is working elsewhere in my app! Here's all the pertinent pieces (let me know if I've left out some important details):

I already have KeyPreview set to true in the form properties I'm working on a small program, and I'm having a problem where it seems that some of the controls on it inside groupboxes are not triggering the KeyDown event on my form when I press and release any arrow key, just the KeyUp event. Specifically, I've enabled KeyPreview on the form, and set breakpoints on e.SuppressKeyPress = True in both subroutines, and only the one for frmMain_KeyUp hits the breakpoint.
I added in the two GroupBox events hoping that might mitigate the issue, but no such luck. However, I have a custom control on the form that is specifically coded to ignore these keypresses, and the code works as expected on it.
Private Sub frmMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown, GroupBox1.KeyDown, GroupBox2.KeyDown
e.SuppressKeyPress = True
Select Case e.KeyCode
[code]....
The code in the user control that "ignores" keypresses is as such:
Private Sub TileDropDown_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyValue = 40 OrElse e.KeyValue = 38 OrElse e.KeyValue = 39 OrElse e.KeyValue = 37 Then
e.SuppressKeyPress = True
End If
End Sub

I implemented auto complete in vb.net textbox , but there is an issue that when user types something in text box the auto complete suggestion list blinks and disappears like if the focus changed
here is the code:
Dim Bl As New ItemBL
Dim suggestions = DAL.DisplayLikeNameList(Trim(MyTextBox.Text))
Dim MySource As New AutoCompleteStringCollection()
[code]....
I believe the problem in Mdi form because it has timer code executed after the above code :
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
LblDateAndTime.Text = Now
End Sub
Note: the auto complete code is executed in a child form not in the Mdi Form , what do you suggest to keep suggestions list "sticky" as the user writing in the text box ?

I am trying to create a document manager for my winforms application. It is not web-based.I would like to be able to allow users to "attach" documents to various entities (personnel, companies, work orders, tasks, batch parts etc) in my application. After lots of research I have made the decision to use the file system to store the files instead of a blob in SQL. I will set up a folder to store all the files, but I will store the document information (filepath, uploaded by, changed by, revision etc) in parent-child relationship with the entity in an sql database.
I only want users to be able to work with the documents through the application to prevent the files and database records getting out of sync. I some how need to protect the document folder from normal users but at the same time allow the application to work with it. My original thoughts were to set the application up with the only username and password with access to the folder and use impersonation to login to the folder and work with the files. From feedback in a recent thread I started I now believe this was not a good idea, and working with impersonation has been a headache.I also thought about using a webservice but some of our clients just run the application on there laptops with no windows server. Most are using windows server or citrix/windows server.What would be the best way to set this up so that only the application handles the documents?

So, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.

I'm trying to load a specific game (Kingdoms at war, www.kingdomsatwar.com) into a web browser on my visual basic 2010 project (i dont mind if its a webbrowser, AxWebbrowser or Axshockwaveflash, it just needs to be in my form).
To answer this question you may need to go the extra mile and join the game to try what im asking Ok so details:
I have a few issues when trying this, I create a form with a standard web browser and change the url to www.kingdomsatwar.com , when it runs it will go to the website however when clicking the login button it will go to a black screen with a bit of writing cut off in the top left corner (which i found out was "Page Loaded"), so thats the first issue.
However this can be temporarily fixed by right clicking and going to "forward" or "play". After this you will go to a login screen where you can enter your details, however after this it will load the game with a "cannot connect security" (which may be a game issue, however i need to know how to make the vbwebbrowser work like internet explorer, which will load it).
This game runs in flash, so i need to know if there is any special way to make the vbwebbrowser work properly like the internet explorer version works with the game.
I tried running the game's url itself (using mochigames), which is http:games.mochiad.../play.swf?q=243 , (i have tried this in the vbwebrowser, axwebbrowser and axshockaveflash) and they all won't load the game (they will load the game when not logged in but wont load an account)
I know this is a very specific question and can probably not be solved but if anyone has some spare time, could they create an account and give it a shot. All i need is a form which will load a www.kingdomsatwar.com account on it.
