Running Same Report Multiple Times With Same Query?
Sep 5, 2011
I have a report that displays some sales info. I have a query that takes the data from an SQL Server database and I store it in a dataset. Up to there everything is ok. The problem is that I need to print the same report using Crystal Reports for each row in my query. Is there any way this can be done? I call a form with a ReportViewer tool to display the reports, wich are basic .rdlc reports.
I have one Private sub that runs in a loop. I want the sub to run multiple times at once. For example the program runs, you press start; you run the program again and press start, again and again... the same program doing the job at once. now i just want one program do to it alone. But i would like it to be user defined. exp. run program. type in a text box 10. press start. and it works as if 10 of them work open working on the same thing.
I am designing a rdlc report in vs2008 for windows application. I want to display the purchase and sales based on department. If i select one department it works fine but have no idea about how to display each department's purchase and sales data in different tables. I have used embedded resource to the report. Report is designed based on the DataTable(on dataset - xsd file) and which contains, ITEMS,Purchase,Sales and Net as Fields. I have attached an image with describes the format that i want to display.
The problem is that the method is getting called multiple times when the text box control gains focus. I am looking for it to just run once since the method is filling the text box control with data. Is there a common reason this happens? Its not looping cause it is happening on everyone of my controls that use the GotFocus method.
This is my first time using the Entity Framework and I'm getting some confusing results. I know a particular table contains 3 distinct rows when I run this SQL query: SELECT * FROM mytable WHERE service_month = 201012
When I run this query against the framework however, I get 3 rows, but they are all copies of the first row (VB syntax). Dim temp = _context.mytable.Where(Function(x) x.service_month = 201012) Did I set up something incorrectly? This is how I'd do it with LINQ to SQL.
which contains a combobox with two Gender options, Male and Female. When the form runs the user can select either male or female to perform a query. I made the ComboBox public and shared so that it can be viewed by other forms. On another form i added a ReportViewer and a dataset based on my database (MS Access 2007 database with 1 table named tblStudents). I don't have any problems when i try to run a simple query without parameters, but there is a problem with my
im trying to fetch rows in 3 TABLES using JOined Queries.im tried the query first in MS ACCESS and it worked but when i tried to show it in Crystal report it wont show its data. [code]
I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]
This is the current code. Rather than put in this 100 times for each number, What would be a better way? Have had a go myself but can't get it to work.
I read the lines from a textfile into a string array and then I use a foreach loop on the string array. I want to go through the same string array again after the loop reach the end of the string array
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
So I took this from an example. GetInstance() is called from hundred different places in my program, and when I debug, the line "Prog = New Program" keeps getting hit for each of those calls. Which I thought was exactly what should NOT happen.. Or do I have some fundamental misunderstanding?
[Code]....
It seems the "New" sub triggers a number of calls to Program.GetInstance, before the first one completes. This is due to me earlier having lots of shared public objects in this class, which are no longer shared since the class was made singleton. And these objects, when initialized, calls the Program class for reference to other of it's objects.
My textbox (txtCopies) default value is 1 so naturally, as it is coded above, the datarow is added once into the Movies Table. But what I need to know is how to code if the txtCopies field has a greater integer value.
I keep on getting errors for every line in the code below that tell me that the attributes cannot be applied multiple times. What does this mean and how can I fix it without changing what the code does?
I am doing a project for my company. In that i have to enter the number of items in the first form and in the second form i am going to enter the details of each items. So i have to repeat the second form to get the details number of times depending on the value i have given for number of items in the first form.From the home page i will be entering the values for the master file. after entering the values for the master file then i have to enter the details of the individual item details in a transaction file.
I'm trying to loop the inputbox 5 times but I'm not sure how. Dim payroll1 As String payroll1 = InputBox("What is the payrolls for store1", "Inc", , , ) Lblstore1.Text = payroll1 I can get it to loop till a specific amount but not 5 times exactly.
How can I tell something to use a code without completely adding it in that sub again? I have some code that will be used alot within my program. I could write a DLL, but I don't know how to use those!
Here is my code:
Dim str1 As String = System.IO.File.ReadAllText(Me.OpenFileDialog1.FileName) Dim s2 As String = str1.Replace(".[1gs5]", "a") s2 = s2.Replace(".[u775]", "b") s2 = s2.Replace(".[fsef]", "c")
I have a button where I get data from a database that matches a search string I enter. Everything works fine the first time the button is clicked. However, if I click it again with a different search string, I get the same results as the original search string. I've tried to dispose, clear, and reset my dataset before I load the data each time, but it still finds the original query. This is the code I use to get and request the data:
Private Sub btnCfind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCfind.Click mdbFile = "TCICUST.DBF" mdbCond = " WHERE COMPANY LIKE '" & cbCust.Text & "%' ORDER BY COMPANY " GetDB() [Code] .....
I have a DGV in VB.Net 2008 connected to an Access DB table. The DGV is not Read Only, but is full of read-only columns except for one, which contains a combo box. The combo box allows the user to select an outcome for that particular row, and then the program copies in a pre calculated value into the "Profit" column depending upon the item selected in the combobox. Then the user hits the Save button and the DB updates (currently via SQL methods in the XSD).
Easy enough so far.
Here is the code.
Private Sub DGUserBets_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGUserBets.EditingControlShowing
[Code]....
The problem I have is that it would seem that if a user selects the desired outcome from the combobox but does NOT hit Enter, and simply mouses on to a different combobox to again select the outcome for a different row, the first eventhandler is not disconnected and thus the events fire multiple times. This then causes various default MsgBox errors and brings up problems when the user tries to commit all changes to the DB/exit program etc etc.
What do I need to do? Do I need to .EndEdit somewhere appropriate to force the row to save the changes? And where should I call this?
I am trying to programmatically add an unspecified amount of new UserControls to a form. One will be added every time an entry is selected in a ComboBox contained within the UserControl. Problem is, the SelectedIndexChanged event fires completely erratically. Sometimes twice, sometimes 3 times, etc., but never just once. No matter how many times I set the combobox's SelectedIndex to -1, it fires at least once with a SelectedIndex of 0. Sometimes the Itemselected event fires multiple times inbetween SelectedIndexChanged events.

I have a number of forms which have a common menu strip rather than copy the control onto each additional form is it possible to just call the menu from another form ?
I want to search data and then populate on a datagrid. I write the name and I click the button and it does work well, but then if I want to search for another name, I write the new name and when I click the button again the datagrid comes empty. No data at all. I will put my code'[code...]
I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something
Im using a datagridview filter as described [URL].. When the user right clicks the dropdown on the filter twice i get an error "Showdropdownlistbox has been called multiple times before hidedropdownlist".
Im not entirely sure how to avoid this or what the solution to this is.
I know this sounds really bad but I can't seem to figure this out. I am creating a template to use in a form. I have a few buttons that when I click on them will auto type out text into a rich text box. I figured it out for just typing in the text into the richtextbox. richtextbox1.text = "my text goes here" But if I hit the button more than once it doesn't keep adding the text to the rich text box. How can you program a button to enter a text as many times as you click the button?
I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.
Heres code to reproduce it. Just a button on a form. Dim intTotalTimesClicked As Integer = 0 Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click BlastOfNumbers() [Code] .....
I want to update a database based on the form that is currently activated. I had originally decided to use the GotFocus event. However I now understand that will not work as the form has controls on it. So I then thought I wouls use the activated event. This works but seems to fire multiple times. I put in the following code:
Private Sub frmNewTicket_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated MsgBox("Form Activated") End Sub
I select the form and make it activated and the message box appears about 15 times.Why does it do this? How should I handle this. I only want my code to execute once when the form is activated.NOTE: There are several forms that the users will be changing between, incuding forms from other applications.
