View 2 RepliesHow would I set a Font Properties DefaultValue.
I am currently using:
Dim f as Font = New Font("Tahoma", 8.25!)
then in the property:
<DefaultValue(GetType(Font), "f")>
But the property defaults to "Franklin Gothic Medium" when I rightclick it and select Reset.
[Code]...
Why is the first line not correct? What it wants is a System.Type and a System.String but refuses to work.
When to use this attribute to set a defaultvalue?Mainly, does the initial value need to be set in a PUBLIC NEW SUB as per the response from forum user Michal Burger in this thread?

but it does not work...WHats wrong
I have this simple code,
Protected Sub grdSearch_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdSearch.SelectedIndexChanged
TimeOff.Where = "UserName=""" & grdSearch.SelectedValue & """"
End Sub
Doing so causes this error, 'UserName' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly. Near simple identifier, line 6, column 1.
The datasource works fine before the where property is set.Update: I found the issue but I still don't get it.Adding it. in the where clause solves the issue. Like this,
TimeOff.Where = "it.UserName=""" & grdSearch.SelectedValue & """"

I am using a user control using vb.net. It include the program to retrieve the values from database while giving the paramers. When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]
View 1 RepliesI am a beginner in Visual Basic programming. I am attempting to place a procedure in a module which I intend to Call from somewhere else in my application. The procedure below is almost exactlyhow it was on a form called PersonalInformationMy problem is that I get the error: "txtFirstName is not Declared. It may be inaccessible due to its protection level." I thought that maybe I was getting that errorbecause this procedure was not on the form that it was first written for.

I am updating a legacy application, and it was reading a dll from another project for a Dictionary(of Guid, String) of items and using them.
The requirements have changed, and the method that was returning the Dictionary is now returning an IList.
This is the odd behavior of this; the intellisense is not throwing a cast error, nor is the compiler. It does not throw an error until runtime when it tries to set the Dictionary to the IList.
Example:
Dim someDictionary As Dictionary(Of Integer, String) = New Dictionary(Of Integer, String)
Dim someList As IList(Of Integer)
someDictionary = someList
why the compiler is not catching this?
I have a project in VB 2008 Express, and I made a foolish mistake of assigning a string setting (ie my.settings.mystring) a very long string (the contents of a 115kb text file). After that the compiler threw an error and closed the IDE, now everytime..I open the project to try and get rid of the string the IDE throws an error 'system out of storage...' (my laptop has 4GB memory, ~100GB free hdd space) and promptly closes.

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
View 3 RepliesI'm porting some source code (C/C++) formating macros from VS6 to VS2005. All in all it seemed to work fine after it was adapted to the VS2005 DTE objects. But I'm experiencing a strange error while setting a commented text to the current selection. The following sample procedure shows what happens:

I have written a program that if all if statements are true then it closes out with me.close() without displaying the form. If a if statement is false, then the form shows with some text as to why it failed.The program works perfectly....until I change the form setting "top most" to true, if the if statements are true, instead of the form closing as it should, I receive ObjectDisposedException was unhandled Cannot access a disposed object.

View 6 RepliesI'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
