On compiling a visual basic assembly, int32 variables are cast as int64 for calls to adodb methods that require int32. This results in a method not found exceptions at run time. The unnecessary cast operation can be seen when using reflector to inspect the site of the method call and is not present in the source code.To further muddy the waters when the code is compiled on my 64bit windows 7 machine all is well, but on a 64bit windows 2008 r2 the unnecessary cast is added.
I am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
In one of my forms witch I imported from VB2008 there are all properties saved in the *.resx file. One Property, of the Type System.Windows.Forms.Keys, can contain the Value 'Ctrl+F1' witch compiles fine in VB2008, but not in VB2010. To reproduce, simply add the following to any resx file:
I read somewhere that older VB .net (pre VB .NET 2005?) couldn't use overloaded operators in a C# class. Is it true for overloaded cast operators?Either way do you guys think it's a disadvantage for a C# class library not to include them and arithmetic methods as actual methods for other languages, like:
I'm using Visual Basic 2005 Express Edition and I was just wondering if someone could help me out with a few things? I'm making a Notepad-type program just to clarify things.1. I have a button which adds text to my RichTextBox1 (excuse the name), but when you click it it adds text to the end of the script. I want to make it so the text is added where your "cursor" (the blinking thing which lets you know where you're typing) is, at the current part of RichTextBox1. At the moment I'm using:
RichTextBox1.Text = RichTextBox1.Text + "The text I'm adding" If anyone could tell me the code to make it put "The text I'm adding" at your current cursor that'd be great.
2. I have a Save As button and a Save button. When you click Save As and save the file it works 100%, when you click Save and you haven't saved previously then it works 100%, but after you have saved the file and then click save it doesn't overwrite the file. Here's the code for Save:
[code]...
So if anyone can tell me the code that's needed so it will overwrite the current file 3. I have a FontDialog but I have no idea what the code is supposed to be to make RichTextBox1's font change after you click Okay in the FontDialog.
How can I create a separate class that has the function that adds dynamic text box, so that I will just call that function to my main form. I have the code below that does add dynamic text box but it is already inside the button of my main
I have a text box that accepts an 8 digit hex encrypted string and adds it to a listbox1. Then I have a button that when clicked takes the string from listbox1 and
1) reverses the string 2) subtracts 235 3) Converts it back to a 9 digit number 4) Adds it to listbox2 using the code: Code:
Private Sub decrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles decrypt.Click
[code]...
However something seems to be wrong because it get an arithmetic overflow exception. Does anyone know what happens to be wrong with my code?
I have a VB2008 application that uses SQL Server 2005 Exspress Edition. I was modifying my application and then decided to add a table to the mdf (named "Pipe.mdf"), which I have don many times before, but I must have messed something up when I made other changes. After I added the new table I opened the Dada Source Configuration Wizard to add the new table to the dataset and I don't see the new table to select it. However, it added a copy of "Pipe.mdf" and named it "Pipe.mdf1" to the Server Explorer.
If I delete this copy of the mdf, it appears again in the Server Explorer when I open the Data Source Configuratuion Wizard.
If I add a Table to the copy of the mdf ("Pipe.mdf1"), it shows up in Dada Source Configuration Wizard.
what to change so that the new table appears in the Data Source Configuration Wizard for the original mdf (Pipe.mdf) and not add the copy of the mdf?
Check process handle count:In Task manager, View, Select columns, mark Handle Count to the view.(The process when loaded has about 333 handles)
Operation:The new thread is set equal to an existing thread, then the existing thread is started and aborted. How does one restore the old handle count? Why do the handles increase by a random number and do not revert?
How can Idisposable/CloseHandle/or GC.collect, Finalize() work in this situation? I'm trying to return the handles to their original count, 333, when I start a new thread it adds 4,5, or 6 handles per new thread(even if the thread is aborted and set to nothing).

I have a situation where I want to add penalty charges after every hour. For example if a target is not met it will start to incur penalties. So after every hour an 80 pound charge is given until it reaches the 5th hour where the penalties incur a 90 pound charge. Is there a way of doing this?
I'm trying add a new row to my databaseTo add a new record a pop up form opens (form2) with a textbox for the user to input their name, they then click the save button and the popup form closes and the main form (form1) is still showing and the added row seems to updated in combobox although it is blank!.This causes a new blank row to be added to the database - the data in the textbox is never saved to the database

What I want to do is when The toolbarbutton1 is clicked it checks for the Save () - if txtprojend.Text = "" then it displays the message. So far, it does that but then it closes the form. I don't want it to close the form unless the user adds text in txtprojend, as it is a mandatory field.
I wrote a simple console program (simplecopy) that copies its input to output:
Module Module1 Sub Main()
[Code]....
The output is the content of testdata.txt, but with three extra characters (hex b4 2b 2b) inserted at the beginning of the output. Those three bytes are not there when I run simplecopy without input redirection.
I am trying to create an application that adds the contents of a till to a database. (Does this on two forms into two different sets of db columns) and can pull that back up at a later stage. At the moment, I'm stuck at the first section?

I have to create program that adds the whole numbers from 1 to 1000 and displays the sum in the label. Create a variation of this program that allows the user to specify any starting whole number and any ending whole number (10,000 or lower) and then adds all the whole numbers in that range. Allow for the possibility that a user may start with a high number and end with a low number. Format the label so that commas are displayed and there are no decimal places showing. I need help with the codes.
I am struggling with a simple datatable issue. The following takes a data table that is on the form and adds an arraylist to it as the data source. The data that shows up in the datatable is the length of the value of the element in the arrayList.
How do I control what is displayed in the columns? What I am ultimately trying to do is have a datatable that the operator can edit and the changes reflect in the underlying data structure.
