I am new to this forum. I have created a module in which declared one structured in public. There were some fields earlier in the structure.
[Code]...
I have included statement includes project.modulename in my main project form where i am referring this structure. everything worked fine. Today, i added new field to the structure by name "example as string" and written some code in module itself to access this field. even this is working fine. but when i am trying to access this field in the main code it is not showing example as structure field and saying not a member.
The drop down suggestion of IDE is not showing this field in main code but in module code it is showing the field. Later, i also found that my debugger is also not working. I tried to clean solution, restart IDE, computer but nothing seems to be working.
I am trying to update a element from login table but it not showing any error massageor any thing execution is error free but finally whenever i check the database its notupdated.. i'm using access2007 database with vb 2008
I am using vb2005 with ms access database.I have a datagridview to show the reports for users.One of my datagridview coloumn is to be allowed for change the string value. Currently editing is disabled.Which is the best method to change the value of that particular cell and updating the same with database.

I have two tables namely BankAccount and MoneyTransfer to be used in a single form. Here lies my form: Attachment 72574 In the BankAccount table I have got the AccountNo,BankName and CurrentBalance columns.I am fetching the data of these columns during the form load event and filling up the combobox's of the From and To part as shown in the form snapshot. So I did this below code in the form load event:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsEtech_TransferEtech_TransferBankAccount.mdb") con.Open() [Code] .....
Now I have a Date and Amount field in the form and I have both the columns present in the TransferMoney table. The user will first select the BankName and AccountNo. from their dropdown list,then enter an amount in the Amount field and ontransfer button click the money will be transfered from the FROM part to the TO part and the BankAccount table will get updated by the current balance of both the FROM and TO part and the Transfer money table containing the Amount and Date column will also get updated by the Amount transferred and the date in which the money is transferred.
this is somewhat related to my previous issue which was solved: [URL] Now my problem is none of the affected controls are changing on the form. The form itself is not frozen as an elapsed time is going fine on it. when I "F8" thru the code the I see the controls contain the correct values and if I do a messagebox display of the control contents it displays the correct value. but the controls themselves do not change on the form. for example: label1.text will still show blank even though thru code it contains "test". what am I missing here?
In datagridview,i want to display the amount without decimals. so whatever values coming from backend,i'm directly assigning to cells value.then in cell formatting event, i'm formatting values without decimals,so here after formatting,the formatted Cell Value not reflecting in Original value. when i read the formatted value , its displaying only assigned value not formatted value..ex :
Public Class Form1 Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load DataGridView1.Item(0, 0).Value = Val(12.123)[code].......
Basically the question is, Why are NONE of the changes I've been making in the designer reflecting on the program when it runs ?'none' is in bold because I've tried moving everything around and nothing seems to be affecting it, it's like it's reading from a different design file, I tried reloading the project and that did nothing, and none of my code affects position of any items on the form (way too much to post it all)
I am working on an application which involves serial port communication with stepper motors. Now I am sending queries to the PLC via modbus protocol. There is one query in which I ask the PLC for the current position of the moving motor and display it in a current position textbox using a DO Loop. Here the problem is the textbox only displays the position at the end of the motor movement and not while the motor in movies though I have included the code to do so inside the DO loop.

So pls anyone who has the solution for this or any other alternative to perform this type of dynamic data display updation then pls reply.
I am using a class to track if a user cleared their personal information found within some text boxes on a form. In the button click event to clear the text boxes I am creating a new object to the class and assigning true to one property value. Sounds simple until I try and submit the form with a different button, and create a another object reference that I use in an IF statement to check the property value for true. Every time the statement fails because the value being returned from the getter in my class is false.
I am developing an application on VB2008 with MySql as database. I opened the connection without any errors. I have three fields/columns in my database and on the form. When I am running vb form data is not reflecting on to form fields.
I have written the following code in form load event. 'Dim cn As ADODB.Connection 'Dim rs As New ADODB.Recordset 'cn = New ADODB.Connection 'cn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=in_out;" + "UID=root;" + "PASSWORD=pacvision;" + "OPTION=3;" 'cn.Open() 'MessageBox.Show("Connection Opened Successfully") 'rs.Open("Select * from deptno", cn.ConnectionString, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)
I have 3 text boxes that are related on a form. They come from the same dataset and the same table in the dataset. The 3rd textbox is defined in the table as the product of textbox (really the column) 1 and 2. The problem is when I save after changing textbox 1 or 2, 3 does not update reflecting the new product. I have a different form using a different dataset that does a similar setup correctly. What could be the difference between the 2 forms or tables or dataset that I could look for?
I have a backend database in MS access, which is updated using excel as front end. Due to network issues the record updation takes lot of time. Would it be faster if i use VB.net as the front end.
There is one-to-n relationship (foreign-key relationship) between tables As and Bs. Every time a new record is added in As, a trigger "after update" in table As creates n records in table Bs. There are two Linq-to-SQL classes A and B representing the tables As and Bs respectively.The class A contains Bs property an EntitySet(of B). Similarly in class B, there is a property A, an EntityRef(of A)
[Code]...
When above function is executed the result is always 0. Whereas there are six records new records has been added to table Bs every time the above function is executed.
the access data are not getting reflected on the DataGridView unless the form is reloaded again. I am acessing the MSAcess data for back end processing (SELECT,DELETE)using odbc connection and displayin on .NET form using DataGridVew

When the button is pressed, it all works and the following files are created: yahoo.dll and yahoo.pdb My question is this: What is the code to load the already compiled yahoo files to execute the code again, without having to recompile the code?
This code was posted in Chit Chat and everyone is saying how great it is. I just have Visual Studio 2010 and no familiarity with VB6 so I thought it would be good to convert the code to Visual Basic 2010.
this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.
I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

I have been playing around with different types of native code operations in Visual Basic and then inspecting the code with Reflector to see what kind of MSIL is produced. For example, I wondered, in a one line If-Then-Else different than an If-Then-Else split onto multiple lines, ie.
what is wrong with my code and I get no feedback from my button click event, i have imported. ( code Below) and i have tied differrent combinations of the code without sucess.maybe add extra to my code for the list to show open Port or closed ports.
This code is for 2008, 2010 and later versions of VB.Net as it uses an extension method.Please note: If you are using an earlier version ( or you do not like extension methods ) please see the next post.Here is the code I posted on Monday April 30th, 2012.>>Now you can specify the startRadius to be
I have this string just down loaded of a Unix server. I would like to remove the box (0x0A) Unix end line code; then replace it with CR+LF normal ASCII code. Also, I would like to do the replace before I save the data, while it in memory.
I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one! Am I doing something wrong?[code]
