[code]Whenever my GridView populates, if there is no value to return from my _dataSet for a field, my GridView stops populating after that. Shouldn't it skip that and continue populating the rest of the grid? It seems the GridView won't accept an empty/null value. is?
View 2 RepliesI have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
Asking for little guidance again... For my custom control, I grouped some properties in some class. Then in the main control code, I use:

A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.
View 1 RepliesI have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB

My windows application uses a webservice (sql server backend) and now I'm trying to create a new form that has a datagridview control on it and I'm uncertain how to set it's datasource. I'm using visual studio 2005 and I have little experience using the datagridview control. In my webservice, I started the code that will be the datasource - should i be returning a dataset? I know that this code isn't correct, but I'm not sure what it needs:
<WebMethod()> _
Public Function SetMyDataSource() As DataSet
Using DBConn As SqlConnection = New SqlConnection(sConnectionString)
SetMyDataSource= Nothing

I have a chart control and datagrid in the same page.
I want in a single button click, to populate them both using a datareader.
I have this code:

The problem is that only one of them is populated (the first databind in the code) and the other databind isn't working.
I have a tab control in my form and inside it I put a listview. What I wanted to do is populate the listview everytime I clicked on each tab. But I don't know how to do it.

I am having trouble with .net again. I have a series of 10 text boxes. I want to be able to populate them from an array and read there values into another array. In vb6 I would create a text box array with 10 text boxes / indices. I could then populate them by txtbox(i).text = arrVal(i) and to reference them arrVal(i) = txtbox(i). I am stumped I can create 10 text boxes on a form if I have to, but I want them somehow tied to each other as they were in vb6.
View 1 RepliesI know the code to find the input boxes in question.. basically the html is like so HTML <input type="text" name="username" class="inputbox"> i know enough to use WebBrowser1.Document.Forms.GetElementsByName("username") to find the text box...but I need to know how to send the contents of say TextBox1.text to the form on the web page...i can't figure it out for crap...I just assume give up and use sendkeys to tab to the textbox even thought its 80% unreliable....
View 2 RepliesI have a VB.NET application that I wish to store on a shared server. It is a GUI application that also calls a few external .dll's. I'm running into an error message that says "That Assembly Does Not Allow Partially Trusted Callers". I've seen several posts that mention I should add the following line to my AssemblyInfo.vb file:
<Assembly: AllowPartiallyTrustedCallers()>
This still doesn't seem to solve the problem. Anyone know what to do? I'm hoping to compile and store the .exe on the server for other users to access.
I decided to get rid of some of the junk in my computer, so I selected all the .tmp files and deleted (nearly) all of them. I then emptied the recycle bin... Then I set to work on trying to get some code to work (in an excel 2007 macro enabled workbook).
I now have two problems: 1) excel will not let me record a macro and 2) when I run one sub routine, excel tries to run every sub routine associated with the workbook.
other than removing and re-loading Office 2007? I'll try logging off and then logging on again - if that works, I'll let you know.
First, I changed my ILS function to be simply: Public Overrides Function InitializeLifetimeService() As Object Return Nothing End Function
Then I included this in my Program as well as A. As Timiz0r pointed out, Form inherits MarshalByRefObject, so I didn't have to include a Inherits statement on my main class (which already inherited Form). This was the big thing, because I didn't include it originally. Next, I changed my AppDomain setup to be:
Dim _ADomain As AppDomain = AppDomain.CreateDomain(Name)
Dim item As New A
item = CType(_ADomain.CreateInstanceAndUnwrap(GetType(A).Assembly.FullName, GetType(A).FullName), A)
With these changes I can now use separate instances of the DLL COM object as desired.
Original Question I am writing an application that creates a list of objects, each referring to a DLL, and each object placed in its own AppDomain to keep the instances of the DLL from interfering with each other. Taken another way:Program maintains a List(Of A)A is created as an instance of AppDomain using CreateInstanceAndUnwrap Each A refers to mirror.dll, which is including in the application's references

I have a transparent layer on the top of a form. I need to display only some part of that transparent form.
-edited- If you think of a map and traffic signal icons displaying on the map. There are a map image layer and a traffic signal icons layer, which is tranparent except icons. if you move the map location, the traffic signal icons should move along with. if the certain area of map does not appear on the screen by moving, corresponding traffic signal icnos should disappear as well. This is what I am trying to do here. Moving the trasparent form is straightforward, but I need to hide some portion of that transparent form.

I added an image as the background image for a form in VB.net. When I run the program, after approx. 5-6 seconds, the image partially overlays itself, as in an offset overlay of the underlying image. I never had this problem in VB6, but I did have it the other time I used a background image on a form in VB.Net.
View 1 RepliesI have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay

The strange thing is that for other forms in my code it works well and starts with the form_load function.
I've been looking around on the internet for something to do this, but I have not found anything straightforward. Can anyone help? I just want to draw an image that pretty much "Highlights" an area in a bitmap. Anyone know how to do that?

View 1 RepliesOut of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.
