Able To Type The Text In Search Box(textbox1) And The Datagrid Shold Adjust At The Same Time
Mar 19, 2007
I have a form. it has a textbox called textbox1. form has datagridview called datagridview1 on it which has datasource set to: tblEmployee. Which is connected from EmployeeData.mdf. This is an SQLServer connection.
I want to be able to type the text in search box(textbox1) and the datagrid shold adjust at the same time.
So if i am typing "Joh"... the datagrid should automatically change to narrow rows with Forename that has "John" in it.
I want to be able to type text in a search box (textbox1) and have the datagrid adjust at the same time. My datagridview is called DGEstudent and the data source is dataset2 and is pulling from the student table. As soon as I start typing in the textbox my datagrid just goes blank. Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
Dim dv As DataView = New DataView() dv.Table = DataSet2.Student dv.RowFilter = "First_Name like '" & TextBox1.Text & "%'" DGEstudent.DataSource = dv
I have got the following code for if in textbox1 the would be appear as 10:10:00 AM and in textbox2 the time will appear as in 4 hours time slots automatically as 06:10:01 AM ..if the textbox2 time will be 06:10:01 AM then MSg box will appear that "You can not registered to this site because the 4 hours time slot will be over " [code]Remember in textbox1 the time would be any .....and textbox2 will auto generate time according to textbox1 to maintain 4 hours time slots between textbox1 and textbox2
I'm making a program that I need to put a button in that when you click it it sends the writing in form1's textbox1 one to the email you type in dialog1's textbox1.
Basically I have a textbox and button on Form1 that when you press it opens dialogbox1. In dialogbox1 there is a textbox and a send button. I need to make it so when you press send it sends an email to the email adress you type in the textbox and the body of the email is whats in textbox1 of form1.
I have a program that reads a file with Pacific Daylight Time, I want users to see the time and date in their local environment.
At present I have in Australia a time difference of 18 hours, so I have a list box with -24 to +24 and currently set at 18, my code is elementary as long as I have moved past day one of the month it suits me personally, but I want to distribute my app, so I need something better.
I have a text box setup to filter a datagrid. Work just fine, but if I search for something that is not there (empty results) it comes back with an error "Object reference not set to an instance of an object." on the bolded line. How to fix that error?
so i have this data grid, which i wanna search , base on specific criteria from two or more text boxes; eg a user wants to search employees from karachi, so they enter karachi in the first text box. now they want to search employees from karachi whose status is permanent, so they enter permanent in the second text box, and the data grid shows employees from karachi whose status is permanent.
For search from ONE text box, i have used the following code :
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp If TextBox1.Enabled = True Then
[Code]....
im no champ at vb, i just started some 7 days ago for my computer project, so ill really need to be spoon fed the details :|
In some text boxes I enter times like "08:00 16:00" then another textbox next to it will display 8 hours then a label at the bottom calculates the total overall hours. There are a total of 7 textboxes for times entered and like the example above and another 7 for the calculation of that days hours worked. My problem is when I enter "08:00 16:30" the total hours in that text box would be displayed "8.5 hours". I need to tweak this so it is displayed 8 1/2 hours. My second issue is that the label that displays the overall hours only calculates if I enter times like "08:00 16:00" if i entered "08:00 16:30" it would not calculate
Here is my code: vb Private Sub txtMondatTimeKeeping_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtMondayTimeKeeping.TextChanged, _ txtTuesdaysTimeKeeping.TextChanged, txtWednesdaysTimeKeeping.TextChanged, txtThursdaysTimeKeeping.TextChanged, txtFridayTimeKeeping.TextChanged, _ txtSaturdaysTimeKeeping.TextChanged, txtSundaysTimeKeeping.TextChanged CalculateHours() [Code] .....
I have noticed in a windows-based VB application I am working on when the "Automatically adjust clock for daylight saving changes" is de-selected, the time in the application is off by one hour. Is there anyway to make the application not sensitive to that and just display the date value that is retrieved from the database?
I am trying to search a Access Db via a TextBox1 a Button1 and a dataviewgrid.My sql statement loks like this:
Select LastName FROM Clients WHERE (LastName LIKE 'TextBox1.text')
This doesn't work I have tried '" & "' around the textbox words I've tried '& TexBox1 &'. This I tried to learn from Data over forms video-- LIKE @LastName +'%' that really didn't work. If I use = "Bla bla" it will work but the LIKE word does not. Even a point in the right direction. I've spent many many many hours on this. And what makes me mad is I've done it somhow before even with a combobox as a variable in the SELECT "var" but anywayI'm wondering now if the LIKE statement isn't used in Access? and if the % wildcard is used in Access?
I've created a private sub called addIRCRoom Which makes the Tab and the TextBox, but i can't figure out how to update the text in the TextBox.I've made this function to handle it:
Private Sub displayOut(ByVal Channel As Object, Optional ByVal User As String = "", _ Optional ByVal Message As String = "") Channel.Text = "<" & User & "> " & Message & vbCrLf End Sub
But i just get this error all the time: "Public member 'Text' on type 'String' not found."how to update the text
Possible Duplicate: cancel plane ticket before 4 hours of departure time if dep time is 08:00:00 AM then Passengers can cancel ticket till 04:00:00 AM ??
I have two textboxes textbox1 and textbox2 in asp.net(vb) webform I want If in textbox1 the time would be appear as 08:20:20 AM Then in textbox2 the time would be automatically generated 4 hours before as compared to textbox1 i.e ( the time in textbox2 the time would be appear as 04:20:21 AM )
Means simply logic i want ... if the time in Textbox1 is 08:00:05 PM then autogenerated time in textbox2 will be 04:00:06 PM Means whatever the time in Textbox1 the textbox 2 will autogenerate time in 4 hours time slot.
in this program that Im making I need to print something that the user have saved in a textbox. And the problem is that the text wont auto adjust to fit the paper, it just keep running on the same line outside. I tried to use printsetupdialog to setup the margins but the settings wont apply when printing, here is the code:
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
Just a quick question my textbox1.text seems to get focus when I run the APP.how do I cancel any focus to any textbox?I just don't want to select it or anything when I work with it only when the user select or uses it.
But i am now trying to declare time however i keep getting an error because i cannot get the type correct. I tried the following but get the following error: "Conversion from type 'Timespan' to type 'integer' is not valid".
Dim DeliveryTime as DateTime Dim DeliveryTime as Integer
In my database the DeliveryTime type is set to Time(7) so i would assume there should be 'Time' which i could use to declare it, but there isnt. What is the correct type i should be using?
Here is my exact code. There error is Input string was not in correct format:
GraphDate4 = String.Empty DeliveryProducts = "{ name: 'DeliveryProducts', data: [" If DataReader4.HasRows Then
Let's say that you have a texbox labeled TexBox2 and you don't want it to be seen when the program runs because TextBox1 pulls information from TextBox2 and it shows up inside of TextBox1. How would you go about doing this?
I have a generic Class I'm using to hold information loaded from a database.I have a method which takes a DataRow as an argument, uses the object's known column name and extracts the data from the DataRow, such that:Dim loadData As T = CType(myDataRow("myColumnName"), T))works as my default assignment in most cases.Unfortunately, due to some horrifying design constraints, some of my columns may be null, and may also be taken from enumerations.This means that when <T> is Nullable(Of SomeEnumeration) the above code does not work because I can't cast 0 directly to SomeEnumeration.Zero.Is there some way to check whether <T> is Nullable(Of [Enum])? Or some way to write a method which allows Integers to be cast to Nullable(Of [Enum])?I feel like I'm forgetting something that would allow me to write one of the other of these, but my weak google-fu is turning up nothing.
EDIT: Okay, thanks to dasblinkenlight's answer below, I can detect when this circumstance is occurring, but what I need to do now is to take a type <T> which I know is Nullable(Of SomeClass), get a type reference to SomeClass and then create a new object of type Nullable(Of SomeClass) and assign that to LoadData.My problem was that I had a lot of difficulty in finding any function which would accept baseType as an actual Type.Parse accepted baseType as a parameter, I knew baseType was an [Enum] type because of dasblinkenlight's code, so I was, in this instance, able to code a solution. It's a solution which is very specific to my problem (i.e., T is Nullable(of SomeEnumeration)), but it's a solution nonetheless.
