Im struggling with gettings the values from the correct strings.txt in my resource files in my in folder when switching languages. I have a [URL] (for English) and a domain.nl (for Dutch). It however doesnt seem to matter which domain I use and how I set the currentUICulture, the language shown to the user is always the same!

View 1 RepliesI have a string in which for sure there is a date in the following format: YYYYMMDD. So, to identify 14 October 2009 I'll find 20091014.Having this string, how can I format into System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern?
View 4 RepliesIt seems that I have problem changing System.Globalization.CultureInfo.CurrentUICulture value according to the user preferences (.net 4.0 web application). In my Web Application, I have two buttons. One for the Greek Language and one for the English Language. When the buttons are clicked a request goes to the server asking to change the user preferred language. For Greek, I send "el-GR" and for English, I send "en-US". On server side, I use the following piece of code to change the Current CultureInfo:

I'm having a problem over here; I'm developing a DirectX 9 application, and for some reason, I can't figure the way to close the application completely. This has never happened to me, to be honest. I am using Application.Exit(), which doesn't seem to do anything - it just closes the form, but the program is still running. I have also tried End, but it throws a run-time error I can't seem to figure out.

I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.
View 1 RepliesWhy does the following code: A = not IsDBNull(CurRow("BuyBook")) AndAlso CType(CurRow("BuyBook"), string) = "Yes" results in the following error:
Conversion from type 'DBNull' to type 'String' is not valid.
This form works in VB .NET
sendMsg = "<CStatus timestamp=""0"" " & _
"type=""login"" " & _
"cid = """ & cID & """ " & _
"key=""" & loginKey & """ />"
But I can't get it work in C#
sendMsg = "<CStatus timestamp="0"
type="login"
cid="" + cID + ""
key="" + loginKey + "" />";
It does not give the same effect. I want this as an output:
<CStatus timestamp="0" type="login" cid="var_cid" key="var_key"/>;
Is there any stringXml command in C# or another way to use double quotes in string?
Solved it with XmlTextWriter
For some reason I can not get some fields to calculate correctly. It seems anything I enter over 24 in the Pay Rate field it throws it spits out the exact numbers I am trying to multiply. The FWT (0.2), FICA(0.08),and State fields (0.25) respectively.

View 4 RepliesI 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.

View 11 RepliesIve seen that people use Form.Close() and Application.Close(), but what if I have many forms, and I may have forgot to close one of the forms correctly, is there a way to exit the application that actually checks to make sure that all the processes related to the program are closed first? I read on another forum that Application.Exit() is a bad way to close the program, and I found an example code of how to do it the right way, but Ive never found this anywhere else before.
View 3 RepliesI have a issue with loading a collection. The issue is that when I load a collection up with multiple objects that the only items that are in the collection is duplicates of the last object that was added in. I was through the process of creating the new object and it is loading correctly but when it adds it to the collection, it changes all the prevoius objects with the current object. Here is the code that I am using. I have been messing around with this code for a day now and can't figure it out.

how do you correctly dispose a shape in vb.net ie when you draw a rectangle using the pen function how do I depose it so that it will disappear from the form, for some reason once its drawn if I draw a new shape it keeps the previous one and just overlays the new one and I use shape.dispose, and pen.dispose?

I have a single form called 'FolderSelector' with a label, textbox and a button.The problem I'm having is that everytime I run the application, the only thing that shows up is a blank form called 'Form1', the program runs everything it should do except to show the actual form which is really weird.Here's the code in case there's something in there that's causing it that I haven't spotted.

View 5 RepliesI'm developing a program (VB.NET Form) that has printing function, then i have to alert user when an error occurred such as paper out, paper jam or etc. I found that .NET has WIN32_Printer class use for retrieve printer information and status. I can get printer status (Idle, Printing) correctly except offline, but for DetectedErrorState... always get 0 if printer has no problem and 2 if any problem found. (from reference 0 means Unknown and 2 means No Error) How can i get printer state correctly? Is this related to printer manufacturer or their driver? Because their application can alert correctly, i guess that driver never return value to WIN32 Class.

My problem is my event is returning zero. Therefore I believe my code is somehow flawed.
My approach is to create functions that calculate the required metrics. I have only tried to code one function to date. If I can get help making one function work, I will be able to do the others .
