In my project I am using a LINQ to SQL class that contains a stored procedure which includes a string value as an output parameter.So to capture that, I created a string variable as follows in the procedure:Dim spOutput As String? However, when I do this I get the following message "Type 'String' must be a value type or a type argument constrained to 'Structure' in order to be used with 'Nullable' or nullable modifier '?'"
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
I'm trying to make a message box appear, I don't want to have to declare the message box as a variable, And I don't want it to be in it's own Sub!I just want it to print (variable) S, It's in a sub. Just not sure of the structure of that code. Just a really quick example
I have a device that sends messages to the serial port. The problem is that the message length varies based on the data in the message. Also, there is no control character at the end of the message so I dont know when the end has been reached.If this data is streaming in, one message after another, how would I go about breaking up each message? The first three bytes should always be the same, but they could also occur somewhere else so I am somewhat reluctant to use those as fixed sync bytes.[code]
i am having real issues trying to build a sql string
Dim SelectQry = "SELECT * FROM TblSupplierQuotes where TenderNo='" & Me.txtTenderRef.Text & "' AND KMBPartNo=" & " " & Me.lbKMBPartNo.Text & " " in SQL the TenderNo is varchar(50) = L003141T75-2012JANTEN KMBPartNO is text = 442 019 115 1
when i run this command i get the error Incorrect syntax near '019'.
We have an excel spreadsheet with about 10000 names (company and email address) and we need to send some legal docs to them. I'm looking for a way to automate this either via a macro in excel or templates in outlook.Problem with macro in excel is that the code I was able to findcustomize doesn't let me insert a formatted text in the message body.[code]...
I need to read an xml file, and then build windows folders from it.How can I recursively keep track of the starting point of each node to know how to grab the string properly for the folder name?I have the following xml, and wish to get strings such as the following (to build folders):
Im currently working on a project to build an application for Windows Mobile 6.I have a SQL query string:
Dim connectionString2 As String = "Data source = " + path + "HC.sdf" Dim cmdText2 = "SELECT * FROM BigC_Rangsit_0_"
I want to substitute the table name ie. BigC_Rangsit_0_ with a variable which contains the table name.say, during runtime the user selects a table from the dropdown list , that variable should be substituted with the selected table name dynamically in the SELECT statement.
Dim cmdText2 = "SELECT * FROM "selected table name VARiable""
I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"
After adding a string to the program from the resources the build always fails, and removing the string and the code to load the string does not solve the problem, as the build still fails. We've been using multiple versions of the program since this started happening with the most updated one, and adding the string is what started the failure in building even though we added other elements (like an exit button) and other forms without it failing. With the one that started with the build failures we've tried it on all types of computers and it does not manage to build on any of them, even one's with a new installation of Visual Basic Express 2010.
The exact line added that apparently makes the build fail is:
And the string added to the Resources isn't anything unusal compared ot the rest we have but it is this is:
The Stegmaier Brewery business began in 1857 when Charles Stegmaier first set up a shop. Since then the Stegmaier business has grown greatly. The size of their operation has grown from the original shop to the large building pictured to the left (opened in 1863 and purchased from Stegmaier in 1978). The Stegmaier Brewery Company was purchased in 1974 by Lion, Inc. and Stegmaier Beer is still produced today by Lion, Inc. and remains a popular choice among consumers.
well in a database is saved a binary code (this is a *.jar) i need to download this code (with a select query) and Rebuild this file
What are the setps for convert since a String to a File?
someone told me i need convert it to array byte, but i dont know how to convert a String to a array byte... what are the best steps?
this code return me a table
Public Function ConseguirCatalogo() As DataTable Return conn.RegresarTabla("select archivo from catalogo where id= (select id from periodos where actual=1)") End Function
[Code]....
now what are the next setp for convert it finally to a file? ( it is a *.jar)
These is the content of my txt file which is saved in D drive in my pc abc,1,2,3..I tried the flowing but it didn't work:[code]I am getting error on this line.. data = line.Split(","c)...it says this line isn't in use anymore or something and that I rather use LineInput but thats asks for filenumber and i don't know what that is. I am sorry but I am a complete beginner. what else can I try? [code]ok that error is gone now but now if I want to add these values to a list box..how can i do that?
I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String()) Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex))) End Function
I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.
I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments
1. Source address (0-255) 2. Destination address (0-255) 3. Function code ("0001" through "0100") 4 Packet Data Unit (pdu - some integer value
just found out that replace(string does not do the same as string.replace when my string variable was an empty str the first one returns "nothing" and the second returns an empty string (as expected).just sloppy coding anyhow, it was a function that was converted from classic asp and never rewritten properly. [code]
I have a Form with a Media Player in it. Which plays a Song.
[Code]...
It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.
I have a VB application. Within this application, I have two "pages". I'm trying to access or change data from one of these pages from the other. So, for example, let's call the pages 'Page 1' and 'Page 2'. Let's say I'm working in 'Page 1' and I want a MessageBox to pop up when you click a button and I want the message box to contain the value of a string from 'Page 2'. How would I do that? I think if I had the answer to this one simple question, I should be able to solve all of my problems. I understand the basic structure of VB, but I can't figure out how to tell the program to access data from another page within the application.
A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?
I have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?
I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?
I just created a simple application. I Builded that using build->build myapp. I got .exe of that application. i runned. all went fine. but when i closed that app, even after closing it is in memory. it is still running. how to deploy it properly?
