Receiving Error Message "Value Of Type Decimal Cannot Be Converted..."?
Mar 20, 2011
I am taking my first quarter of programming and am having a VERY difficult time understanding jagged arrays. At the moment I am working on a project that is using two two dimensional jagged arrays
If IsNothing(g_decChargesArray(g_intActivePatientNumb er)) Then
numVisits = 0
Dim decTemp(g_intActivePatientNumber) As Decimal[code].....
The line in bold is the only way I can think of to pass the amount of decCharges into the array g_decChargesArray.
I have a problem, I cannot converted the value of Integer type, which it cannot converted to 'System.Drawing.Point' and 'System.Windows.Forms.Control' .
[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
I have been trying my hand at this for some days now and just cant get anything to work. Below is the code im currently using to delete a row from a database table, the problem when trying to build the project line 5 is giving this error about the value con" Value of type String cannot be converted to 'System.Data.OleDb.OleDbConnection' "
Dim con As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=Customers.mdb" Dim cnn As New OleDb.OleDbConnection(con) cnn.Open()

I have also tried using this code below, but to no success. Im basically just looking for something rock soild that i can use to accomplish this task. Been stuck on this for quite a while now.
vb Dim s As String = strContents '<a global variable) Dim currentPos As Int64 = 0 Dim endPos As Int64 = strContents.Length - 1 '// A dictionary, used to count the frequencies Dim characterCounter As New Dictionary(Of [String], Int64)() While currentPos <> endPos '//
[CODE]...
Gives this error: Value of type 'System.Collections.Generic.KeyValuePair(Of String, Long)' cannot be converted to 'System.Collections.DictionaryEntry'.
I am trying to insert a variable in Decimal type into an Access table. When I use "decimal" field with 0 digits after the decimal separator (,) my program works properly. However, when i use the field with 2 digits after the separator I get a "Data type mismatch in criteria expression." exception. This happens also when I try to update the table. The debugger shows me that my variables contain the right values but the update or insert command gives the error.
Im trying to set one variable equal to another but it says "No default member found for type 'Decimal'" what does that mean?Both the varuables are deciamls, one is a regular decimal that I declare in the sub and another is an array that I declare in the class. The line is:
I don't understand why the line final.join etc pops up with these errors!! Value of type 'String' cannot be converted to '1-dimensional array of String' And Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated This is my code.
However i get the following error: "Value of type 'String' cannot be converted to 'System.Uri" How can i set it so that it is set in the correct format?
I have to create a calculator. In order to do the calculation, when the math operator is entered, there is a space on either side, so that I can split by the white spaces.
[code]...
This was my original idea of how I could accomplish my goal, however, I get an error message saying that splitNumbers cannot be of type string. Do I have to create an array to do this or is there an easier way than what I'm seeing?
I need to do this to every line in a file and save the # five Element in an array. I keep getting (error code 1 Value of type '1-dimensional array of String' cannot be converted to 'String'.)
NOTE: if I change ( Dim Lineoftext(1) to Dim Lineoftextt works) (It does't seem to work with arrays)

I am attempting to make a browser. I have a menu drop-down where the user can choose one of a couple colors. I set up each button, panel, text, etc... as my.settings. I have tried to write the code two different ways, but neither works. How would I fix this?

I am running a web server using VB.net and I have a bunch of pages that need to utilize similar functionality, so I was thinking of creating a shared base class that incorporates all of this shared functionality. I created a file call it SharedBaseClass.vb, and I also have a class that should inherit from this class, SubClass.aspx.vb. The Top few lines of the the parent class look like this:
Partial Class SharedBaseClass Inherits System.Web.UI.Page
And of the child class that should inherit:
Partial Class SubClass Inherits SharedBaseClass
Then at the top of the SubClass.aspx file it looks like this:
Assume that all of these files are located in the same directory.But when I try to run this, I get an error:Compiler Error Message: BC30002: Type 'SharedBaseClass' is not defined.And then the highlighted error is on the line that reads: Inherits SharedBaseClass I've also tried importing the file to no avail.
I have an Vb.net application made by a third party , that I need to control using outside resources from a simulated environment and must not interact with the desktop. To simulate inputs that a user would normally input from a special screen with specific keys around it, I've built a test control library to control it and send the form image to a .bmp. The form cannot be visible and showed in taskbar , the bmp output will be displayed by the simulated environment.Using PostMessage and sendKeys work well as long as I don't but ShowInTaskbar = False for the main form. After many read & testing, I have learned enough to try what seems to be the only thing that would work. I've created a form that I setparent using HWND_MESSAGE parameter, this should create a Message-Only Windows, that are supposed to received postMessage, and subclass it's events.msdn.
I can't seem to get it to work, and I was hoping someone could tell me what I'm doing wrong.I have been testing several different ways found through out the web about .net , and short of going into message thread peek and feed(maybe(may be)my last hope), they all seem to work until I take the forms out of the taskbar.[code]
I believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).
I am developing a chat application in asp.net using vb.net. In this, if a user receives a new message from other users then I want to play a sound to let him know that he received a message. I wanted to play some .wav files.
I am currently developing an SMS application to read and receive SMS. I run the application and tried to send an SMS and the application indicates that the message is successfully sent. However the recipient did not receive the SMS. I am using Sony Ericsson T610 btw.
