I am currently using the registry to get file descriptions for files. As an example, so that a DOCX file will return the description "Microsoft Word". I am doing this from the HKEY_CLASSES_ROOT registry key.However, registry access is extremely slow, and I need to do several thousands of these. Is there an alternative way to do this?

The only way I can think of to display this moustache is by creating a new form and locking it to a certain point, that all works.My problem is with all the events surrounding this. E.g. minimizing the actual application etc...I know how to handle those in code but that is painstaking as I have to think of every possible event which would result in a problem then manually code for the moustaches relative actions. So, I would like to know:
View 2 RepliesI've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

How do you get at this "type of file" information with .NET?

I've a simple class like this:
Public Class CalculationParameter{
public Long TariffId{get;set;}
}
In a workflow activity, I've an Assign like this:
(From tariffDetail In db.Context.TariffDetails
Where tariffDetial.TariffId = calculationParameter.TariffId).FirstOrDefault()
Dto is passed to Activity as an Input Argument.It raise following error and I'm wondering how to assign Id.LINQ to Entities does not recognize the method 'Int64
GetValue[Int64](System.Activities.LocationReference)' method, and this method cannot be translated into a store expression.
How can I assign the calculationParameter.TariffId to tariffDetial.TariffId?!
UPDATE:Screen shot attached shows that how I'm trying to assign calculationParameter.TariffId to tariffDetail.TariffId (car.Id = Dto.Id) and the query result should assign to CurrentTrafficDetail object.

I am Using Visual Basic 2010 Express. And the Express Version Does Not have a MicrosoftReportViewer Facility. But is there an Alternative that can be used. I know Monies have to be made But Surely there should be an alternative For the Microsoft Visual Studio/Basic 2010/2008 Express User.or is there another way to create a reportViewer in Visual Studio/Basic 2010 Express. I have Downloaded the MicrosoftReportViewer Redistributable from

I am enrolled in a college course using Visual Basic 2010 Express.My current assignment calls for the following:Create a small program that allows a user to enter the total amount of purchases for the purpose of calculating rewards points based on the purchase totals vs. their membership level of basic, standard and premium.The user selects their membership level via 3 radio buttons, basic, standard or premium.
The total of purchases and their rewards points depend on the membership level. Example, if you are a basic customer and your total purchase is under $75, you receive 5% in rewards points (70 x 0.95). Additionally, if the total is between $75 and $149.99, you receive 7.5% rewards.Here is what I have so far, but I am getting errors on the ElseIf statements:
If basicRadioButton.Checked = True And totalTextBox.Text < 75 Then rewards = total * 0.95
ElseIf basicRadioButton.Checked = True And totalTextBox.Text > 74 AndAlso totalTextBox.Text < 149.99 then rewards = total * 0.925
ElseIf basicRadioButton.Checked = True And totalTextBox.Text > 150 Then rewards = total * 0.9

I have an MDI Windows Forms application (.net 2008) that allows the user to associate various file types with the application. I currently do this with a registry entry something like this, that causes the application to load and access the file name via the command line:[code...]
In the pre-.net version of the application, I used DDE (ddeexec in the registry). If an instance of the application was executing when a file was double-clicked in Windows Explorer, it would open the file without starting up a new instance of the application.
Now that DDE has been deprecated by Microsoft, what is the best way in .net for an executing MDI application to open an additional file when the file is double-clicked in Explorer, as opposed to starting a new instance of the application?
in my database i have an admin form, where it allows you to do admin stuff.Example: Allows you to enter price per membership, and change it.Problem i'm having is how would i save it, since all previous files had more than 1 records, so it would be in the form of:
FilePut(1, OnePerson, NumberOfRecords + 1)
Since this file will only cosist of one record, i don't know how i would save it.i tried FilePut(1, OnePerson, Index) But it doesn't work.
I know album name is usually to music files & stuff probably but I guess album is what I need to categorize my video files correctly in Windows Media Player as it does organize my music files correctly when using album name & title. Anyways, these files I just want to change album name at the least & the description is something else I'd like to change on them as well. These files when I right click & go to properties then over to the details tab will show all the things like it usually does, but it will not let me change them. I am guessing this has to do because they are protected type files but I just want to change some things so they display correctly in Windows Media Player.
It already lets me change attributes inside Windows Media Player & at the bottom pane of the screen in explorer when the file is selected of attributes the file already had, but it won't let me add in the album name & description since it didn't start with one. I don't want to get rid of the protection on the files to be able to add these attributes either as I thought that was illegal or something, plus I don't want to download another program I don't have just to do this, whether it be a protection remover (which I said above, I think is illegal, even if it wasn't or isn't, I still wouldn't want to do that anyways) or even a thing that can change the attributes for me I wouldn't want to download since I just don't like downloading things that I won't use often, even if it's easy to remove & everything.
Since I already have VIsual Basic 2010 Express Edition installed I would just like to code something to change these attributes programmatically. It can be a simple textbox which is the location of the file and a button which changes the album name and description to "Just Text" that way I can put in each file I want to change & then click a button and it will be good from there. I will be able to change the variables after they are there to what I want after that from explorer or windows media player so I don't care for having textbox to change album name & description per file as I can just do this in explorer afterwords to what I want. By the way, files are in .wmv file format.
My problem is, I just finish creating a program, that loads a picture and description of a selection from a radio button.
Everything works on MY comp, but when i go to my lil sister comp and load the .exe file there, everything works too EXCEPT the image....the error is something along the line " C:documentspictures ame.jpg" not found.
My question is: how would I store the image to the program via another file or the program itself. so that when I "build" my program, I just need to run the .exe and lets say another file "for ex: .dll ", with all the images stored inside. And I dont know how to create and work with .dll file or whatever file is more convience.
I use a text file to store the settings from my program.Now when i save the settings the text file gets created and everything works correctly. I can load the settings without any error.Now when i quit my program and star it up again clicking the load button will clear out any data in my text file. So the file still exist but it empty.It happens when my program runs this line of code.
Dim o_read As system.IO.streamReader = system.IO.File.OpenText("C: est.txt")
That just tells o_read that it is a stream reader and which file to read.How does my file get cleared out by that?
I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large
So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?
