• .NET Development OleDb and datagrid

  Hi, I created a simple database using Microsoft Access and I try to display the data using datagrid. However, there is an error occured if I update the change in the datagrid (update,delete and add). The code is the similiar for Sql database and it works fine. So I just don't understand why there is an error.   [code] dim da As OleDbDataAdapter  Dim db As OleDbCommandBuilder = New OleDbCommandBuilder(da)  Dim dsChanges As DataSet If ds.HasChanges(DataRowState.Modified) Then                     dsChanges = ds.GetChanges(DataRowState.Modified)          &nbs ...Show All

• Visual Basic My Data Problems :(

  Hi, I have been playing with this for some time: the transmitter end can only send my data as either a byte or a host of other options (that are not applicable). The problem is that each of my values is 12bits meaning I need to bytes / integer to send them (Basicall y 12bit Analogue To Digital data conversions). So I either send the data byte by byte and get vb to assemble the integer or I send it as an ASCII coded hexadecimal integer (another option on the transmitter side) and send a line feed:- in each case I have found this problem: -- Byte by Byte case: - Data send format :- <Data><Data><Data> …… VB side: - Each time there is data the serial port received event is f ...Show All

• Visual C# Autogenerated Code directory

  I am writting a DLL to control an external device. I have defined my interface. However, I changed the relative path for the main file that has my interface definitions. Now when I try to add new functions to my interface, the IDE gives me an error. If I do this manually it works. I have a lot of functions to add and doing it manually is not the best way to go. Upon close inspection, I discovered that the IDE tries to create another destination file in the default location. How do I make the IDE know where to place the function ito the directory location to start looking for the right file from. The error I get is: "Failed to return new code object. Possibly syntax error. ...Show All

• Windows Forms Cursor not visible after DroppedDown property is set to true

  Hi,      I have a dropdown control with few list item in it. I am setting the DroppedDown property to true in the textchanged event to show the dropdown, the problem is the mouse coursor (the pointer) is not visible after the dropdown is shown, its stuck inside the dropdown and only when the focus comes out of the control I am able to see the Mouse pointer again. Am i missing something. Regards Deepak This problem is reported in Product Feedback ; it is a side-effect of the Windows "Hide cursor while typing" option, set in Control Panel + Mouse. I tried fixing it by calling the ShowCursor() API function but that didn't work. Triggering the dropdown with a timer ...Show All

• SQL Server SQL Server 2000 and 2005 on one machine?

  Hi, i have SQL Server 2000 running on my notebook for learning purposes. Is it possible to run SQL Server 2005 on the same notebook without using virtual machines Thank you, Tobias As others have said, sure no problem. The only thing that I would add is: if this is a production box be aware that the SQL Server instances are completely independent of one another. In a sense this is good because you can start and stop one instance without affecting the other instances. But in another sense this has a drawback. The compete with each other for system resources - memory, CPU, etc. So you may want to adjust the amount of memory each instance can use. HTH... Joe ...Show All

• Windows Forms Disabling TextBox fires Leave event

  Hi, i have a winform designed using Visual Studio 2005 Express Edition. There is one textBox with Leave event for validation purpose. When i programmatically disable the textBox, the textBox's Leave event is fired which is very surprising and not desirable. However, when the textBox is enabled programmatically, the textBox's Leave event isn't fired. Why does textBox's Leave is fired on disabling this control and is there a way to make these two independant Thanks, -srinivas yelamanchili Well, here we are first changing the focus from TextBox1 to TextBox2 (which fires TextBox1 Leave event and is valid). However, with focus on TextBox2 when Button1 is pressed, TextBox1 Leave event is fired when TextBox1 is ...Show All

• Smart Device Development IO.Ports.SerialPort - issue with .BytesToRead and DataReceived Event

  Hi Folkes! I'm currently developing an infrared IR-communication software for PocketPC's with Windows Mobile 2003 SE and Windows Mobile 5.0 The communication is based on:    PocketPC virtual serial-port --> IR    and    IR --> Device serial-port. I wrote a communication-library for windows first, which worked perfectly with a real serial conncetion (no use or IR). The same code should work for the virtual serial-port and IR, since it's only a simple IR serial-bridge. Here comes the issue: It's possible to write data from the PocketPC to the device with .Write() It's possible to read data from the device with .Read() and similar. BUT: it's not possible to dertermine how may b ...Show All
