VS 2008 - Convert The Vba Macro And Display The Results To A Dataset
Jun 28, 2009
I currently have an excel spreadsheet that has a macro that displays information from my sql server. Everything works fine with it. Im trying to embed that into my vb project though. Anyone know what the best route to go would be to do this. Should I try to convert the vba macro and display the results to a dataset?Or should I try to recreate the connection through VB to display the results? or is that sort of the same thing? Or should I try something different? [Code]
I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all. [Code]
I started with not knowing anything and I have built 2 programs over the last month and a half and have learned valuable information from the help of this board. I have 1 last hurdle before I am done and I am hoping to get another tip for this. First of all let me start by explaining what I have done.
I have seen numerous sites that provide examples on creating progress bars. I would like to know how to "call" the progress bar (created as UserForm1) to update a completion percentage of records processed from a Main macro in Module 1.
I have a DataGridView bound to a DataSet. I only want a selection of columns displayed on the DataGridView rather than all. I then have a text box which I want to display a value (Version_no column) from the column not showing in the DataGridView. Is this possible?
Would it be better to have a hidden column on the DataGridView and use this value for the text box?

I've only dealt with firing a single SQL statement at a SQLServer table and returning a single result... easy....
however....
is there a way to fire a dual sql command and load the results into respective tables within a dataset?.. I'm thinking something along these lines (this code of course does not work)
Dim ds As New DataSet Dim dt1 As DataTable = ds.Tables(0) Dim dt2 As DataTable = ds.Tables(1)
I do however have a slight background with VBA particularly with MS Access, so I am not completely lost.I am recreating my Access database application in VB.net.I created a new project and added an Access database through the wizard, which automatically created a dataset for the database. On one of my forms I have, esentially, a search form. What I want to happen is have a text box, and as I start typing display a search result from my customers table in the list box under it. So for example, I type "A" and all customer names that start with "A" are displayed in the list box.I continue typing with a "p" (full string is now "Ap"), then all customer names that start with "Ap" are displayed and so on...
I did search on my own first before posting this and found a few tips but cant really get it to work the way I want. This is what I have... I know I would put this code in the keypress event of my test box, but just until I get it working I attached it to a button to search. (I basically got this online and not even sure its the correct usage.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click 'Create a dataview[code].....
The item in red is where i get an error. it sucessfully builds and i open the find form enter a last name that I know is in the customers table, but I get the error "Cannot find Column ["whatever name i typed inthe text box"].So first of all is this the correct way of going about what I want to achieve?If so how can I get it to work?BTW the next step for the user would be to double click the customer in the list box they are searching for to open the customer Details form for that customer, so I would need an ID or Index attached to that item to be able to open that record in another form.
I have a form with a Listview. I have not manually added columns through the gui so I need to do this too.I have a stored procedure which returns two sets of data. One is titled url and the other occurrences in he procedure.I have bound the results to a dataset. I am having problems taking that dataset and putting the results in the listview. Here is the code I have:
[code]...
It is not creating the column headers. It is not putting both results in the view. It is only putting the first column "url" It is not putting the next row on the next line, but placing it in the next column where the occurrences should be going. It is also not resizing the columns to match the data , but keeping at the size assigned (I assume) in the columns.add section.
I'm have a program (GUI) that interfaces with excel to execute macros. We're using Microsoft.Office.Interop.Excel to call/run the macros and this works great.What I can't figure out is a good way to cancel the macros from the GUI.One idea we had was to use the excel.application variable that runs the macros to write a "stop" value to a specific cell in the workbook, and in the macros (they are all mostly loops), check for the "stop" value in that cell. This crashes my GUI with this The program '[2188] BVLReports.vshost.exe: Managed' has exited with code -336589910 (0xebf00baa).And excel gets tied up, and won't respond. I know how to Exit Sub from within the macro if the "stop" value exists, so I don't need answers on how to check/cancel from inside the macro. Any ideas on a better way to write this "stop" value or a better way to cancel the macros externally?
somehow combine the results of separate Fill queries on a single dataset?Basically, I'm trying to implement a 'Filter' function, whereby, the user can filter the records in a DataSet according to specific criteria.
Heres my issue, I am retrieving data from xml and populating a DataSet with the results into multiple DataTables but i have an issue where an item is repeated in my input data and it is causing it to exception because of the constraints imposed between these tables. how can i determine if a row exists prior to adding the DataRow and thus not include it in my DataTable?
[code]I have a listbox, 4 radio buttons,a textbox and a button. I want the user to type in a number into the textbox, click on 1 radio button(multiplication) and then click on the button to show the number entered into the textbox multiplied up to 3 times. [code]
I can get the results if I plug a number in for i, but I get them as a string for some reason. Private Sub displayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles displayButton.Click 'display Fibonacci results Dim fib(10) As Integer Dim i As Integer Dim fibn As String
I am using a WCF to connect to my database. I have the code below, I am trying to select all the details from the database where the customernumber = what the user has entered on the form.However, I cannot return a dataset to the form as it sends in a string.
I'd like to add a generic search feature to my WinForm application (Visual Studio 2010). I want the users to type in a value (for instance john), and then display a list of any company, contact, or student records that contain the search value in the name[code]...
I am working on a simple program called "Who's Connected?" where it runs a command (netstat -aon) and then displays the results in a multi-lined textbox. However, when I press the button that will run the command, it tells me that it can't convert the string to an integer or something. And when I did manage to get it to convert to an integer, it really showed an integer in the textbox instead of the connections and IP addresses. What do I do? Here is the code I have: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Running command and displaying results in textbox1 TextBox1.Text = CStr(Shell("netstat -aon"))'Results end up being a triple or quadruple digit number End Sub
I'm trying to present results on an aspx web page where a store procedure parameter is defined by a dropdown list control on the page. I have followed this guide from Microsoft and have my resultset presented in a DataGrid view. But I cannot seem to adapt it to present the resultset in a chart.
As you can see from my VB code below, I thought it would simply be a case of adapting the GridView databind to a Chart. I have tried various other options, and have successfully generated my data in a chart using a hard-coded parameter in an SQL statement on the ASP page. But when it comes to using the control, I get an empty chart.
Below is what I have so far.

I'm using visual studio 2010 and sql server 2005 to store my data. I'm creating a system that will allow me to find/search for records that are stored within the database. Thing is, i have 2 separate forms for this - one is the find/search page which allows you to enter in as many fields as you want (the more you enter, the more efficient the search is) and the second one is the find/search results page which will show the results from the search.
I'm not using a datagrid as i've already created these forms myself. I'm on a tight schedule because i've spent so much time already trying to get this to work. Do i need to create another dataset and tableadapter and bind the text boxes? how will i code the find/search button so the search will be carried out and the results will appear in the other form?
