I am writing a basic blog application to learn mvc 3. I have problems retrieving posts by category. The url looks like /Blog/Browse/Category_Name. I can get the posts if i hard code a value for category. So it would seem that Category_Name is not getting pass to my EF statement in my controller. the category had a period in it so it was not matching.

I am having some issues with serial port communication. My event handler to poll data is not working. I even tried to retrieve it using a button event, but that also does not work. I know there is data in the buffer.Here's my

I successfully retrieve a user (call it userA) from Active Directory that exists in Domain A in the users subdirectory. I then try to remove the user from AD by doing
dim theParent as DirectoryEntry = userA.Parent
theParent.children.Remove(usera)
This fails because when I look at the parent node in a Watch Window in Visual Studio, all of its members say COMInterop.Exception.
i'm trying to retrieve the SID of user to eventually set sharing permissions. I somehow missing how to properly set the parameters for win32_account so it autom. retrieves the SID and makes it available through account("SID").
View 3 RepliesThe main problem is I couldn't display the result when I retrieve data from database.
1. On Picture 1 above, for the Dg_Details, I set the Columns in two type, textbox and checkbox. But, for the datagridview1, I didn't set anything.So, when I bind data from database to Dg_Details and datagridview1, the datagridview1 display the data from database, but the Dg_Details doesn't display the data. Below is the code I written in my form :
Try
objCommand = Me.MyConnection_F.open.CreateCommand
objCommand.CommandText = "select Reg_Num, Reg, Golf, Course_1, Course_2, Course_3, Course_4, Course_5 from Invoice_Reg where Receipt_No = '00001'"[code].....
I think that's happen because the Dg_Details already set and it blocked the result data from database.

I am faced with the prospect of having to completely rewrite the application.I have suddenly started to get this error message all the time - it seemed to start after I added a table to the schema, but deleting the table makes no difference. I can't see anything wrong with the connection string, but as it seems to be entirely undocumented, that doesn't mean much.
The connection string contains DataSource=.SQLEXPRESS;AttachDbFilename=|DataDirectory| est.mdf;Integrated Security=True;User Instance=Trueand certainly the string works when I use "test connection" from the application setting edit box. I am assuming that for some reason it is not evaluating the Data Directory , but can't see any reason why it shouldn't. Any ideas gratefully received! What might be a clue though is that I can't get rid of the table I added. I have deleted it from the database, deleted it from designer and saved the file, but it just keeps reapearing! Even when it is not showing, there is still a
table adapter in the .xsd file. I am reluctant to start editing this manually because of the danger of screwing something else up - I did try but it caused an error somewhere else (VS helpfully didn't say where)
Does anyone know what the problem is with this error message? One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

I am using the xmldocument (loadxml) and xmlPathNavigator to parse xml files I am compiling through a incoming stream. The first point of processing the files is to split the file into the different entries and add those to a list. I do this using either xmlPathNavigator or string.split if either one fails.At times both will fail because of some issue in the xml and would still like to salvage the file contents without having to fix the xml. I tried to use regex parsing but its not producing the content as I would like. I use the following code but in the end I do not get all the contents of the entry, only those between some of the tags.

I'm having trouble with a DropDownList within a GridView that posts a NULL value when in fact a value is selected from the list when using inline editing.
The problem is that I can't use this method to bind the value to the UpdateCommand in my SqlDataSource:
SelectedValue='<%# Bind("Value") %>'
The reason for this is because the value might not exist in the list so it throws an exception.
Is there a way I can bind the value to the UpdateCommand without using SelectedValue?
I've seen a lot of posts over time relating to importing and exporting CSV. Most of the answers involve using TextReader.readline and String.split, which will not work with any but the simplest data. When you are writing for users who have the expectation that your application will work with anything they export from Excel, you will have to cover all the CSV bases.
I hope that this post will give you a clear idea of what you're involving yourself in when you decide you need to read a CSV file. The characteristics of CSV data are:The comma character is used to separate the fields. (This is obvious, but I thought I'd start with a couple of obvious points to warm up) The last field on the line is ended by the end-of-line character or the physical end of the file.Any field that contains commas, double-quotes or control characters will be surrounded by double-quote marks. Any double-quote marks within the field will be "escaped" with an extra double-quote character. For instance, the value Paul "Chuck" Norris would be converted to "Paul ""Chuck"" Norris".After the opening double-quote ANY character is valid. Including line breaks. This is why you can't use readline.I have a parser class that works nicely and I'll post that on this thread in a little while, along with some notes on using it.
While I was reading some posts, I got stuck at certain lines.

Ultimately, what I would like to do is upload files directly into the database, so I updated this question with the code I'm using to write to the database. I am developing a module in DotNetNuke using Telerik controls. I need to upload files to the server in the user interface, so I am using the RadUpload control and the RadProgressArea/RadProgressManager.
Here is my ASP:
<telerik:RadUpload ID="RadUpload1" runat="server" ControlObjectsVisibility="CheckBoxes, RemoveButtons, ClearButtons"
AllowedFileExtensions=".doc,.docx,.pdf,.tiff,.gif,.jpg,.jpeg,.xls,.xlsx" MaxFileInputsCount="2"
MaxFileSize="10000000" InitialFileInputsCount="2">

When I hit the button, it does a postback to the page, but the files do not get uploaded. I tried using the autoupload functions and specifying pysical and virtual paths but that didn't work. I did it exactly like they said. I manually registered the controls in my web.config, then removed them and used the auto-register feature to re-register thinking maybe I did something wrong, but I'm still at a loss.
Here's where I spent the last couple hours:

how to create a sub category in vb.net? well I'm thinking of building a sales and inventory system of computer parts and peripherals and here's the logic. I'll be assigning each of them category like for example:
Componenets[INDENT]Peripherals[/INDENT][INDENT]Networking[/INDENT] - Processor[INDENT]- Chasis[/INDENT][INDENT] - Router[/INDENT] - Memory[INDENT]- keyboards[/INDENT][INDENT] - Bridge[/INDENT] - Storage[INDENT]- Speakers[/INDENT][INDENT] -Hub[/INDENT] - Optical Drive[INDENT]- Flash Drives[/INDENT][INDENT] - Switch[/INDENT] - Graphics Card
There you go. and the main categories are: Componenets, Peripherals, Networking and the Subcategories are with the -(dash) on their names if you have an idea also on the database structure please give me also some tips about how to construct the database tables.

I wrote a VB 2010 app on a single core processor utilizing performance counters which runs fine. However the release exe fails on my quad core, trapped by the OS on its first access to a PerfCtr. I've loaded VB Express Studio into the quad core
and when running the app in Debug I get this error "Cannot load Counter Name data because an invalid index was read from the registry." Similarly, adding a counter to the app on the quad machine results in the empty drop-downs for category and it sub fields.
where I can get an update to these registry entries?
