Asp.net - Looks Like A Query String But Won't Act As A Query String
Nov 11, 2011
I am working with VB in asp.net, The basic problem is, I want to pair up the elements in a string, exactly like request.QueryString() will do to the elements in the query string of the web page.
i'm currently making an app that needs to run a query between two dates. this app will run automatically, so i need to put the dates as today and yesterday, essentially.
I make a query in coding. But I got conversion error.My query is below
Dim strSelect As String = "" strSelect = "SELECT " & _ "Description As [Desc], " & _
[code].....
Exception error is like
Conversion from string "iif(CurCons = 0, " to type 'Double' is not valid
Actually, in my report, i wanna show if it's zero then '-'. If i set it in this string.I got another error like below The provider could not determine the Decimal value. For example, the row was just created, the default for the Decimal column was not available, and the consumer had not yet set a new Decimal value.
From da.Fill Dim cmd As New OleDbCommand(strDynamic, m_DBConn) Dim da As New OleDbDataAdapter(cmd) da.Fill(ds, "tblCur")
In my project I need to log all queries executed against my database. As an example we can use the staff user data here. In that class I have a function generating the command with the parameters as follows:
By this way combobox CmbId is storing above sql query ouput. But now i want to get above query ("Select Name from StudentDetails where Id=10 ") result to store in a variable string. How can i do this ?
What I want to do is take the full contents of the address bar and see if everything after the site path (i.e. everything after the question mark), contains a certain string, and if it does then return a path using the site URL and that string. An example and some code to make things understandable:
I have a query string that takes the value from a text box and passes it via a query string to a different web page. I need to add a hidden imput (state=MN) but can't get it to work. Everything I have tried hasn't worked.[code]
But the result of this is that the textbox txtTags will only contain C and doesnt have the ++. I tried [URL]and the # is missing as well. But if I look at the address bar these values are there....
I had been using this way for while, and it seems it work fine with char and numbers. Dim MyVar1 as String = "Hello" Dim MyVar2 as Integer = 1 Dim MySQL = "Select * from table where field1 = '<field1>' and Field2 = <field2>" MySQL = MySQL.Replace("<field1>",MyVar1).Replace("<field2>",MyVar2) msgbox(MySQL)
But, when I have to deal with blob field, where I store "wav file" for example, I had to read it as array of bytes, and the only way I find to insert the array of bytes in my query string is by using the command.AddParameter Dim myfile As System.IO.FileStream = System.IO.File.OpenRead("full_wav_file_path") Dim myArray(myfile.Length) As Byte myfile.Read(myArray, 0, (myfile.Length)) [Code] ..... Is there another way to insert it without addParameter?
Im currently working on a project to build an application for Windows Mobile 6.I have a SQL query string:
Dim connectionString2 As String = "Data source = " + path + "HC.sdf" Dim cmdText2 = "SELECT * FROM BigC_Rangsit_0_"
I want to substitute the table name ie. BigC_Rangsit_0_ with a variable which contains the table name.say, during runtime the user selects a table from the dropdown list , that variable should be substituted with the selected table name dynamically in the SELECT statement.
Dim cmdText2 = "SELECT * FROM "selected table name VARiable""
I'm trying to view data by entering SQL in textbox.There's no error at below codes but I can't view my data.It shows me blank report. Did I missed something?
I am using the method described in the following LINK and I am using the following code to encrypt:
'Page1.aspx Protected Sub butEncrypt_Click(sender As Object, e As EventArgs) Handles butEncrypt.Click Dim QueryString As String = "type=Int&pk=" & _primaryKey QueryString = Tools.encryptQueryString(QueryString) Response.Redirect(/SearchResults.aspx?Val=" & QueryString) End Sub
I'm writing an ASP web application with VB back-end. What I'd like to do is generate a url and display this in control on the page. For example if I have a label and a button on the form. The label is blank. When the button is clicked the following code fires:
Protected Sub btnGenerate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnGenerate.Click label1.Text = "Hello" End Sub
What I'd like to have is a url that would point to my ASP Page with the words "Hello" in the label.
I have a Gridview on a page that have: CountryID, value 2 columns.There are another 2 text boxes on the pageI added a hyperlink field to the Gridview and I want onclick it will take me to another page with a Gridview that have datasource to query based on values of these 3 controls:-
(1) CountryID ofthe row user clicked (2) textbox1 (3) textbox2
I'm trying to create a sql query to search within an Access table that is showing inside a datagrid.
The search criterias used in the "where" bit are retrieved from info entered by the user in 3 textboxes and 1 DateTimePicker control. The first 2 fields are String type, the 3rd field is a date type (entered by the user using the DateTimePicker) and the last field in the DB table is Integer type.[ode]...
I am trying to add data to another column in my table.I have the following string insert which works:"insert into MyTable(ImageID,Image) values(" + TextBox1.Text +"," +" @pic)"The data I wish to add is in TextBox2.How do I correctly concatinate it?
First one is a table with results populated from the sql server backend. The first holds the "FirstName". I want this to have a hyperlink, so when i click on this, it should goto the second aspx page and show all the data in sql server for that "Firstname". the data is in 3 other tables based on firstname, which is phone, address and hobbies.So -
FirstName Samuel --> clicked on it redirect to second page -
Samuel -
Phone Address Hobbies 3104445656 123 main st Climbing
if i need a querystring or is there another solution (better solution). Also how do i capture the querystring in second page?
I am wondering how to replace two variables in a query from selections that the user makes. One variable is chosen by a combo box called cboYEARMONTH and the other is selected from a list view called employeeListView. I know that I can use .replace to insert the YearMonth into the string but, how do I also replace the EmployeeID in the query string?
This is probably so simple however my brain has decided it wants a night off. I am trying to write a program that uses SQL queries for various tasks but I need it to allow the user to be able to use which ever name they want for the database name. therefore I need to be able to reference the database as a string variable. For Eg:
