I created a simple page with one button, then on the click event have it use FindControl, to get a reference to itself. But..... FindControl is returning nothing.
code
Protected Sub EntryDoor1_Click(sender As Object, e As System.EventArgs) Handles EntryDoor1.Click
Dim control = FindControl("EntryDoor1")
control.Visible = False
End Sub
I ran into a situation where FindControl was returning a control that wasn't a complete match of the Id I was searching by. There are two controls in the parentcontrol with similar Ids like: "MyControl" and "MyControlAlternate". When I call FindControl("MyControl") the control returned is "MyControlAlternate". I was wondering if anyone had any explaination why or thoughts as to what might be causing this problem. The way I got around this was implementing my own version of FindControl.
View 1 Repliesi am trying to retain the value of a variable from a previous page. i believe this is the C# way to do this, but i would like the vb.net way can someone please help:
TextBox myTxt = (TextBox)Page.PreviousPage.FindControl("previousPageTextBox");
currentPageTextBox.text = myTxt.Text;
i would like to know how to code this in vb.net i tried this:
Dim myTxt As TextBox = CType(Page.PreviousPage.FindControl("Textbox1"), TextBox)
TextBox1.Text = myTxt.Text
but i got this error msg:use the new keyword to create an object instance
Ive tried searching for hours now and cannot find out why my code (aka, me.) is failing
Basically... I have a listview control which I'm passing a datatable of products (ID, Name, Description and Price columns), and im trying to make it so that when the "checkout" button is pressed, it parses through all the controls on the page, finds all the controls with the correct ID's and adds the items values to the cart.
ive checked all my ID's in the source code and they match up to the ones being requested by the FindControl method.[code]...
In my global.asax.vb I have a rule like so:
RouteTable.Routes.MapPageRoute("defaultRoute", "{*value}", "~/default.aspx")
So, if someone enters:[URL]...Even though that page doesn't exist, the application pulls up default.aspx
Now, if this wasn't using a wildcard it would be easy to pull this value in on default.aspx like so:
Dim prospect as String = Page.RouteData.Values("value")
But this doesn't seem to work with wildcards, e.g.:Dim prospect as String = Page.RouteData.Values("*value")
How can I get the page to pick up these variable values? e.g. one time might be janedoe, another johndoe, another goose, another 12345, etc. Whatever it is, I want it to be returned into the string prospect.
I'm making a game that makes use of Control.MouseButtons and GetActiveWindow() like so:
Private Declare Auto Function GetActiveWindow Lib "user32.dll" () As IntPtr
Public Sub GetMouseState(ByRef x As Integer, ByRef y As Integer, ByRef lButton As Boolean)
Dim p As Point = Parent.PointToClient(Windows.Forms.Cursor.Position)
x = p.X

Does GetActiveWindow() not return the correct value only when my game is running?
I have this problem that just recently started happening.I've created this snippet that isolates the problem, which is basically, the same VBScript that used to return all of my users from Active Directory, now only returns the first 100 users.If I filter by group, then i get all of the groups (which is more than 100).The problem started happening last November, then went away for a while and has come back.The server guys tell me that nothing should have changed there.When I run this script for various domains, i get a numbered list of just the first 100 users.I'm running this on IIS (which hasn't changed)[code]

I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.
My stripped down View (of type IEnumerable(Of MyTable)):
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
[Code]....
What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.
So In Default.master.cs PageLoad I have the following[code]...
However this is causing the following exception!object reference not set to an instance of an object.

View 4 RepliesI have created a windows form application which goes through Internet Explorer index.dat files and extracts various information (URL's , date they were last accessed etc). I then display this information in a data grid view. From here i would like to be able to click on a URL link and open the web page without activating any active content (such as java script, activex, viruses etc). I have tried to do this using Internet explorer in 'offline mode' with the problem being if the web page requires an online connection it automatically changes Internet Explorer from 'work offline' to online mode. Is there a way around this problem? Or does anyone have any suggestions on a better way to view the web pages with no active content?

View 2 RepliesI am using this vb.net code file to call a procedure to get dates (among other things). When I execute this procedure in SQL 2005 Server Management Studio, I get about 10 columns. However when I execute this code, the dataset seems to only have one index value, maybe I am misunderstanding something. When I change this
ds.Tables(0).Rows.Count.ToString
to
ds.Tables(1).Rows.Count.ToString <---changing the index value to 1
(or higher)
I get no information. So my question is;
Does the DataSet contain the other columns, only not indexed like an array? What I want to do is choose which of the columns to filter out and turn the rest into JSON formatted strings.

I have created a function which essentially enables me to output anything I need from my database in a similar method to Facebook's FQL querying method as a JSON text result. I can also use the same function to get the output as a Dictionary, or List of(Dictionary) to use with VB functions for other purposes.

View 2 RepliesI wanted to create some CLR functions that will access Active Directory, but I discovered I can't add a reference to "System.DirectoryServices" to my CLR project.
I googled it, and found that I have to add the AD dll as an Assembly to the SQL Server. Like so:
CREATE ASSEMBLY [System.DirectoryServices]
FROM 'C:WindowsMicrosoft.NETFrameworkv2.0.50727System.DirectoryServices.dll'
WITH PERMISSION_SET = UNSAFE
GO
The problem here is that I have to set the "PERMISSION_SET = UNSAFE" to the dll... this means that I have to set the database as "TRUSTWORTHY ON", and this opens a can a worms!
I have done VBscripting the past and I have actually made this work in a script however I am trying to convert it to VB for the client so that it has a nicer interface and basically is a better program. There are several parts to this program but I am stuck on this part right now. I am attempting to get a list of all servers from Active Directory and then sort them by type. The program will run however it will not produce any results. Its just an empty file. I figured the problem was with my filtering but I just don't understand why this will not work. I have written it in two different ways and get the same result each time.
Imports System.DirectoryServices
Imports System.DirectoryServices.ActiveDirectory
Imports ActiveDs
[Code]......
For example, a user logs in and sets his status in SQL Server to active. While using the program, it suddenly blacks out. The status in SQL Server remains active. When the user logs in again, he can't access the same account in the program because in SQL Server the status remains active. How can I set the status to inactive during blackouts?
View 1 RepliesI have a Search web reference (from a Search Server 2010 express install) in a vb.net application that is utilizing the QueryService Class to search a production Sharepoint foundation 2010 site.At a previous point in time, we had created a proof of concept on an entirely test system that has since been turfed. From my recollection on this test system when documents were uploaded as a specific site content type (that inherits from document) and metadata was provided, we could search for specific metadata by making managed properties for each, and search results would be returned as documents (with the isdocument flag set to true). Viewing the document then became simple, as we could simply use the filename and path to display the stored file.Now we are developing a production system and we have encountered a new behavior, where these results now are returned as aspx results such as
[URL]
This of course makes it terribly difficult to locate and view the document, we can extract the Title which will then give us the name of the file with no extension, but that hardly helps, as the FileExtension data is aspx, not the documents file extension, so we don't have a full filename. We could display the page returned as a result, but would much prefer the document itself.
I've made a test document library, with just bare bones setup, (not using the site content type, or site columns) and uploaded some documents on the same site, and they are returned in the same fashion, so I don't believe the document library, or content type are the issue.
With a fairly limited understanding of both Sharepoint and Search Server, I don't know if this is a setup issue with the search service itself, with the site configuration, or with the querypacket I am sending. We also have a third party application (Knowledgelake) installed on the server that ties into sharepoint which could have changed configuration somewhere as well?
I don't think the query packet has changed since it was working in the proof of concept, other than the custom data column names. I will provide it here in case there is something glaringly obvious to an external reader.
<QueryPacket xmlns='urn:Microsoft.Search.Query.Document'>"
<Query>
<SupportedFormats>

View 7 Repliesi need to find a control in a repeater in my asp.net application.At the moment I'm using FindControl("IdOfControl") and this is working well.
[Code]...
I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?
I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:
Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString()
Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)
If Not (myOrgName Is Nothing) Then
[Code] .....
[Code]...
But none of these work for me.
I have a DataList inside a DataList that causes my page to lose the controls. The page works and there are no errors, but my label is never found! This is odd because the label shows on the aspx page, it just doesn't remove the 2 items that I want it to remove. When debugging, it skips over the If statement altogether:
If lbl IsNot Nothing Then
If lbl.Text = "Self Directed" Or lbl.Text = "Systems" Then
lbl.Visible = False
[Code]....
This will only hide the text for "Systems", I have gone through each label in that particular question and each has hidden itself. This code does work on another page so I know that Self Directed is exactly how it is capitalized. I even copied and pasted from the database and it still wouldn't hide.
