i have a question maybe someone can help me, i have a form in vb 2008 with a datagridview connected to a table named (kunden) that have 4 colums the data connection named (kunden2.sdf)
one of these colums named (telefon_N), i have a textbox in the form, what i want is that when i enter a telefon number in textbox
it makes filter for the data and return the row with the same telefon_N in the datagridview
I'm using a dataview and bind it to data grid view. Currently my data is shown nicely at data grid view, and I successfully added filter: itemDataView.RowFilter = "item_id LIKE '" & Me.txtItem_ID.Text & while itemDataView is my dataview, and txtItem_ID is a text box to allow my users entering filter parameter.
This code runs nicely, but the problem occurs when a user enter special character(s) like an apostrophe (single quote " ' ") or an opening square bracket " [ ". Is there any way so that I can escape this characters? Currently I'm replacing each one of them using text.Replace()
itemDataView.RowFilter = "item_id LIKE '" & Me.txtItem_ID.Text.Replace("'", "''").Replace("[", "'[") & "'"

i am currently working on a database project using Microsoft Access 2007 and VB Express 2008.my problem is, i want to create a searching function in one of my tables; table Coachee. I know that it is possible to search data using bindingsource.filter as i've already succeeded in doing that. The thing is, how do i actually prompt a messagebox saying that the record of the Coachee ID to be searched is not found? [code]

search textbox (fillby method)
combobox (bound to the data)
datagrid

I am trying to filter the results of a datagridviw using the bindingsource.filter method.
Dim filters(2) As String
...
If Me.txtPartIDFilter.Text = "" Then
[code]....
The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
I have files that start with unique numbers and are word documents. Say the document starts with "1234567" is there a way to make the OpenFileDialog filter to where only all the .doc files that start with "1234567" show up?
View 2 RepliesI have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

View 1 RepliesI am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

View 3 RepliesI want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable
Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.

I have a code which can get the MAX value of distinct "SYSID" field. Now, I plan to add a data filtering by time - Start and End time. I have tried but getting all sorts of error and can't get what I'm after for. So the program should do the data filtering (data >=starttime and data <=endtime) first before getting the max value of "SYSID"
Below is my
Private Sub Get_Max()
Dim ci As New CultureInfo(CultureInfo.InvariantCulture.LCID, True)
Dim dtfi As New DateTimeFormatInfo()
dtfi.ShortDatePattern = "MM/dd/yyyy"
dtfi.ShortTimePattern = "hh.mm.ss"
