I updated my DataSet with a new string column called WorkingEmployee. I dragged the WorkingEmployee onto my form and it seems to work ok, except when I change a value it does not save to the database like everything else. Any ideas on whats going on?
View 8 Repliesi was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?
View 4 Repliesi have a sql database, and have created a dataset for a sample table in it.The dataset is HotelDataSet2 and data table adapter to insert to it is Various_itemsTableAdapter.
MsgBox(HotelDataSet2.various_items.Rows.Count)
Various_itemsTableAdapter.Insert(Item_nameTextBox.Text, itemcode, PackingTextBox.Text, UomTextBox.Text, PriceTextBox.Text, RemarksTextBox.Text, TaxTextBox.Text, StatusCheckBox.Checked, Rate_inclusiveCheckBox.Checked)
MsgBox(HotelDataSet2.various_items.Rows.Count)
This always reflects the same count, before and after inserting..But if i execute this
[Code]...
it shows the new count to be +1 of the old one. So i concluded that everytime i change some data to the table via table adapter, i have to always refill the dataset?? How is that useful then??
Where am i going wrong with this line of code? I think its with the (REO/Bank_Owned_Desc)

There is no column REO is REO/Bank Owned Desc, I would think it doesnt like the /between REO and Bank.But that is what the column is called in the database.
I want to add value to column called [DateDifference] ,the values equal the diference between other column called [date of consumed] I want to subtract all the values in this column from the minimum date in the column exe: the values will insert in [Date differnce] column 0 1 10 15
The code I wrote but it doesnt work

I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:
Products Table:
Product_ID Product Name:
Topics Table:
Topic_ID Product_ID Topic
[code]....
I don't know if I'm making myself clear, but I basically need to do the equivalent to the following SQL statement: "SELECT PRODUCT_ID FROM Products WHERE PRODUCT_Name = LstProducts.SelectedValue"
[code]Gets me one column called Length with the size of FullName in it?
View 1 RepliesI have an XMl string in a Field of a mySQL Table. I load an XMLdocument (xmlDoc) from that string
I then Search for a node and change an attribute. All good in here.Then I want to save changes that i made to the XMLDocument in string format so i can update my table in the DB.
How can I do this.?
If I execute xmldoc.save(), well, it will save a XML file. How can I save the changes that I have made but instead of savig the file, save it as a string so I can save it in my table.I really do not want to parse the XML string as a normal string to search my parameters and save it.

I have a string that contains a slew of text that I'm returning from the server.
I wanted to know if that string can be called on the client-side?

Here is exactly what I am trying to do... I am trying to code my application to navigate to a website (my own) and fill a web form.
The only way that I know to do this using the web browser is to have the information in the document_completed section of the browser. This works great but once I compile the code and setup my application I don't have any way to update my application with new websites.
What I was trying to do is go ahead and code my web browser document_completed with about 5 of my websites. I would need to have the ability to update my application with new sites and the only way I could do this was to create an update and patch my current .exe of the application.
My work around was to try to create a generic sub routine, in the sub routine I would tell the application to navigate to a folder, read each text file in a folder (which would contain the document_completed code for the webbrowser) and then put the code into a string...finally I would call the sub into the webbrowser.
The thinking behind this would that I could add/remove website by just adding/removing the txt files in the folder.

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]

I have the following line of code in my program:
JCL_History.Enqueue(JCL_History(I))
This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:
Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))
[Code].....
In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.
After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.
So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.
I have a dataset column which is "newsID".I want to get the value of it's last record so that I can use it as a default value or starting point to auto increment when I add a new record using the BindingNavigator.

Im working on a roguelike console RPG. For those of you that dont know, just google search it.What I need help with is that I have an string array called ArrMap(0 to 19) that holds the 20 rows of each map for display. I also have an array of the same size called VisibleMap that needs to hold which portions of the map are visible and which arent so that when the player switches screens [IE goes from map, to inventory] they can go back to the map and it will look the same. I was thinking of using an array, but if you can think of another way to do it, that's fine.Here are the subs that deal with the map reading and display, so you know how I have things set up at the moment.

I am making a combobox from my data source. Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field.

I need to know how to display the First and Last name (both are seperate columns in the table).

it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)
