Unable To Display Files?
Mar 12, 2011
I have a lot of files in my computer.Here is an example: C:Data3023e4rMarch_20113023e4r_03112011_062334.docC:Data3023e4rMarch_20113023e4r_03142011_092301.docUnder the folder March_2011 has a lot of doc files. The file name string 3023e4r is the serial number,03112011 - the date created,062334- time created.I'm planning to have a text box,where i could enter the serial number. then it will display the files under March_2011.I want the filename string to be displayed in datagridview column with their respective heading(SErial number,date, & time)

I wrote a small VB6 program to monitor the status of a Shared Network Drive. In this case it's an external hard drive. The drive is used for backup. The program is invoked automatically when the computer is booted and runs minimized.
If the backup drive is not turned on or otherwise not functional then the program changes from minimized to a normal window and displays various statistics and a warning that the backup drive isn't working.
I want to make the warning much more prominent, like minimizing the program that happens to be running or displaying the warning window in front of the progrmam that happens to be running. I want something really noticaeble. The computers don't have speakers so I can't play an warning.wav .

I'm using VB.NET 2005 RC and I have built a custom component which consists of a search screen, data grid, dataset etc. The whole project is designed to be imported in to any new application as a custom control which can then be programmatically changed via its methods, events etc. When I tried to import the .dll in to a new windows forms project all the extra stuff contained in my project was also magically imported (such as the dataset I had used, the SQL connection) etc.I have set these their modifier to be private but still they are imported.
What can I do so when a developer imports this custom control in to their toolbox for use, only the control is shown? Otherwise it looks a bit weird to have access to the dataset I'm using with access to the dataset I'm using within the control.

So I have a class that I use to filter the results of a datagridview in vb.net. And one of the things I want this class to do, is keep the column order, width, and visibility.
So what I do, is when my search class is instantiated, i create a copy of the columns in a hashtable, for later referencing.
Private dgv As DataGridView
Private dataSet As DataSet
Private bindingSource As New BindingSource

Using data binding and ado i am controlling a listbox selection (draws from an access database) based upon a combobox selection. Problem is i want to display more than just one column.The code i am currently using specifies the displaymember and value member on form load. However, i cant seem to be able to specify multiple display members.
Heres the code i am using on load.
Bindingsource1.datasource = a_dtBuilding
Listbox1.datasource=Bindingsource1
Listbox1.displaymember = "Building"
Im sure this is easily solved although i have read i should use a listview instead of a listbox for this.

I designed a vb.net application. In this application I am using some file which are in WindowsSystem32 folder. Each and everything is working file, but when I install my application on any x64 machine. My application is unable to read the in WindowsSystem32 files. I think this is because of WOW64(windows-32-on-windows-64) issue. I don't want to install these files at any other place because of application security purpose.

The main problem is I couldn't display the result when I retrieve data from database.
1. On Picture 1 above, for the Dg_Details, I set the Columns in two type, textbox and checkbox. But, for the datagridview1, I didn't set anything.So, when I bind data from database to Dg_Details and datagridview1, the datagridview1 display the data from database, but the Dg_Details doesn't display the data. Below is the code I written in my form :
Try
objCommand = Me.MyConnection_F.open.CreateCommand
objCommand.CommandText = "select Reg_Num, Reg, Golf, Course_1, Course_2, Course_3, Course_4, Course_5 from Invoice_Reg where Receipt_No = '00001'"[code].....
I think that's happen because the Dg_Details already set and it blocked the result data from database.

I have a VB.NET application that will let me preview .DBF files that come in from some of our clients. The application then attempts to spit out a CSV from this file that we can then use in our various environments. This application worked under Windows XP 32 bit. Our company recently upgraded most of us to Windows 7 x64 which has caused this application to fail. I verified that the target build for this application is x86 and not "any CPU" and rebuilt the app but same issues occur.
It originally used System.Data.Odbc and connection.ConnectionString = "Driver={Microsoft dBASE VFP Driver (*.dbf)};SourceType = DBF;SourceDB=" & dbfSourcePath & ";Exclusive=No; Collate=Machine;BACKGROUNDFETCH=NO;".
The location of the failure is at connection.Open(). The error given is: "ERROR [IM001] [Microsoft][ODBC Driver Manager] Driver does not support this function".
I noticed that the drivers for VFP were not installed and that the Access DBF drivers did not work similar to the post here. The fix listed there is to install VFPro SP2, however, we do not have any FoxPro installs to install a service pack on top of. I then tried to install the OLEDB driver for VFP 9.0 and am now using System.Data.OleDb and connection.ConnectionString = "Provider=VFPOLEDB.1; ourceDB=" & dbfSourcePath & ";" but it now tells me that the connection.Open() line has this error: "Feature is not available".
I am at a complete loss as to how to get this application to work under Windows 7 x64. Below are the 2 variants of the code with the file open path removed for readability (I have verified the path and file exist):
ODBC version:
Imports System.Data.Odbc
Dim strSelect As String
strSelect = "SELECT * FROM " & dbfSourceName
[Code].....
How can I use either an OLEDB or ODBC connection to open these .DBF files under Windows 7 x64?

I have a form1 with a splitcontainer. I have put a button on the left panel, whenever user click the button, form2 will be displayed in the right panel.The question now is, i am not allowed to highlight the textbox in form2 with mouse. But i still can use the keyboard to highlight.
1) Replace textbox with richtextbox
2) set formborderstyle to Windows.Forms.FormBorderStyle.None.
The code i am using to open the form in panel:
B_frmMaintain.TopLevel = False
Me.scMain.Panel2.Controls.Add(B_frmMaintain)
B_frmMaintain.Show()
