I have a VB2005 application where the PC waits for data packages from a target. Part of the data package contains what to do next. I am using SerialPort1_DataReceived thread to pickup this data package and "looking" at and extracting the "next step" data from the package then go do it. The issue I have is I must exit the SerialPort1_DataReceived thread to do this and not do everything inside the SerialPort1_DataReceived interrupt routine. In C there is something like this:

I am trying to use a scrollbar to move forward and back through records in a datatable and to populat an entry in a field to indicate that individual records are selected.In short i want to represent a the sum of a specific field of those records selected. Of course being a scrollbar it has to work in reverse and unselect records when the user moves it backward.
The purpsoe of the scrollbars is that there will be five of them and they will represent years. The records on the other hand represent projects which have an output (say money saving). The idea being projects selected in year one then cant be selected in year two. I am planning to do this by assigning a value that indicates they are already allocated to the previous or other years scroll bar. I can set up a loop to go through the whole data set and do this for a year (and have), but i want to use scrollbars and make it interactive.

I am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)

I am working on a project and the code for FORMS1.vb has become quite large, 20K lines.How can I break this down into more managable pieces. I have tried Modules but I get multiple reference errorsd when I move like all of the reporting code to a module. The report code has nothing to do with the forms other than being able to call that code from an object on the form.

Bulk Insert is only breaking every other row. I've tried every ROWTERMINATOR I can think of, but none of them will break all lines. I've even tried to break it on exact text, and it won't break it on that exact text. I've attached a pic and circled what appears to be the line break that it refuses to recognize as a line break. When I open it up in notepad, it recognizes it as a line break.
View 7 RepliesHiI'm trying to get a multi-line, word-wrap enabled rich text box to display text with non-breaking spaces in. For example, '20 000' should always appear as one word, not split onto the next line.I've tried {20'a0 000}, 20{'a0 }000, {20~000}, {20emdash 000} and so on. Nothing seems to work.During my searching, I did see a suggestion somewhere that the DLL that the rich text box is based on doesn't support non-breaking characters.
View 5 RepliesI'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?
View 1 RepliesI'm converting a asp.net application from .NET 2.0 to .NET 3.5 I have loads of inline code like so:
Dim Total = 0
for each dr as DataRow in dt.Rows
Total = Total + dr("SumOfAmount")
next
Response.Write(FormatCurrency(Total,2))
Notice that there is no explicit type declaration of the total variable.This code worked fine under .NET 2.0 Under .NET 3.5, the Total variable is defined as an Integer, therefore the total is being rounded to the nearest dollar on every pass.I know one solution is just to change
Dim Total = 0
to either
Dim Total as decimal = 0
or
Dim Total = 0D
However I'd prefer to not have to visit every page in the system looking for this problem.Is there any site wide, or page wide option I can set the change this behavior back to the way it was under .NET 2.0?
I have used the openfiledialog on numerous occasions, and it has never caused a problem. (This is also happening to savefiledialog as well...) Put simply, its breaking my application..
Code:
Private Sub LoadMapToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadMapToolStripMenuItem.Click

Even this bare minimum code, is causing most of my application to stop working. I have an onpaint method which should be drawing my map, it starts throwing exceptions(file not found), I checked my paths they are correct, I have a listbox linked to a picturebox, clicking a image' name in the listbox, loads the corresponding image to my picturebox, this stops working too..The program isn't hung, I can navigate my listbox, open menu's etc,.. It's breaking everything that has to do with images. I would post code, but, it's quite extensive, and the problem seems to be centered on the opensave dialogs.. (again, I have used this same code without trouble, so many times I have lost count, I'm at a loss as to why its acting up now...) Well, for now I created my own open file dialog, its a little crude compared to the real one, but, mine works..(ie, a standard dialog control, Ok, Cancel, with a ListBox loading the file names..)
In Visual Studio 2005 or 2008, when adding any User Controls to a Windows Form or other User Control in a Project that implements and is using a custom settings provider, a "Failed to create component" error is displayed. If all references to the custom settings provider are removed from settings.settings and that file is saved then User Controls can be added to Windows Forms and User Controls. However, if the custom settings provider is referenced again in settings.settings, then opening the designer of a Form/Control which includes a User Control results in a "One or more errors encountered while loading the designer..." error message.
I have had a very difficult time in tracking down the root cause of this issue because I assumed it had to do with my code and not the IDE. I am working within the context of a large project which uses User Controls heavily and have written a custom settings provider to persist user settings to a SQL Express database. This settings provider works properly, however if I want to open any Forms or User Controls in designer view I must first manually remove all references to my custom settings provider in setting.settings and then re-add them after the changes are done which is inconvenient to say the least. This problem is not present if the Project is in C#.
When trying to register a new user on the server, the server will post back messages such as "OK" and "usernameTaken". Upon comparing this returned string with another string (to perform an action based on the returned value), the compare isn't working.
Dim backupX As New CBackup
backupX.startSocket("127.0.0.1", 8888)
Dim str1 As String = backupX.registerUser("user1", "testpass")

Looks to be like the socket code is working just fine.. each Function returns the corresponding Functions' Return value (registerUser -> SocketSendAndReceiveMSG -> sendAndReceiveMSG -> receiveMSG).

I do not want to have to use vb.net to edit the returned string for each line that is pulled
so i have a file that i need to read in vb.net. Each line is 32 chars long and each line consists of multiple fields. Meaning from char 1 to 9 it idicates ID then char 10 indicates an identifier,11-14 indicates a value field. I've looked at Readblock and it's not the tool for the job. Is there a way to break up each line into its respective fields other than just reading the whole line and breaking it up as a string?
View 3 RepliesI've reached the end of my project but I have several unused and not needed .xsd files from trial and error of linking my program to a database. I want to clean up a bit and get rid of them while keeping only the essential files attached to this program. I tried deleting the .xsd files but it seems too ingrained into the program to the point where the program has several errors and just breaks. I have to manually restore the files from the Recycle Bin to get the program to start working again.
What are other solutions to get these files out of the project? I thought about clicking "Exclude From Project" but am afraid of the consequences. I figured I'd check with someone here before taking action.
