Suppress reading data after DataBinding.WriteValue() ezeew4-May-09 21:27 ezeew 4-May-09 21:27  Hi All. I have bound the Text property of several Textboxes to the properties of an Object with DataSourceUpdateMode.Never. A foreach loop cycles through all textboxes and the DataBindings.WriteValue() function is called for each modified textbox to give the changes back to the object (which stores them in a database): foreach (TextBox ctrl in gbCAddress.Controls) { if (ctrl.Modified) { ctrl.DataBindings["Text"].WriteValue(); ctrl.Modified = false; } } This works fine so far, but after calling WriteValue(), all other DataBindings reload the data from the object, which overwrites the changes made to the other textboxes (probably because the Datasource changed ?). Example: textbox1 and textbox2 were modified. The loop calls the WriteValue() function for textbox1 All Bindings reload their data - textbox2.Text is now the old value The loop calls the WriteValue() function for textbox2 Can I suppress this reloading somehow ? I cannot see why everything is reloaded after one field changes... Help !

As you and all people know! the data in those text boxes will change when DB update. so I suggest you to collect your all data in each text box (if it modified) and in the end Update them to DB. (not exactly after modification) I dont know, probably into a dailog form. It depend on you. sorry, my english is not good HOW CAN I COUNT TRANSACTION TIME AND NUMBER OF TRANSACTION??

What do you mean by "COUNT TRANSACTION TIME AND NUMBER OF TRANSACTION" and how do it relate to your XML file???

I'm on a project where the (DB2) queries are all accessed through resource files. I have a visual studio add-on that gives me editor support (color coding, etc) for working with DB2 queries when editing text files with the db2 extension. The problem is that the ResXFileCodeGenerator doesn't recognize these files as being text files, so when I add them to the resource, they get returned as byte arrays. I'm well aware that there are other, better ways to manage these queries, but I have to stay with the design that's already in place. At this point all I want to do is make ResXFileCodeGenerator recognize files with a .db2 extension as text, so the ResourceManager will return them as strings. Thanks.

Mark Churchill4-May-09 19:38 Mark Churchill 4-May-09 19:38  Also you should initialize the count with 1. You can use a different number, and subtract that later, but its not as efficient as just starting with 1.

Need help with Insert, Delete and update commands in VB.NET davos14-May-09 2:06 davos1 4-May-09 2:06  So I made a datagridview, table adaptor, dataset, etc and it's all working fine. I can view data perfectly but I can't save it. I tried doing this: Me.TerritoryTableAdapter.Adapter.Update(Me.TerritoryDataSet.Territory) But it just says I need a DeleteCommand or UpdateCommand, etc. I'm using the ODBC driver for MySQL if it makes a difference. Please help Re: Need help with Insert, Delete and update commands in VB.NET Not Active4-May-09 2:34 Not Active 4-May-09 2:34  You must provide, or have autogenerated, the update, insert and delete commands so the DataAdapter can determine which one to call. You may know that you are only updating a record but to the DataAdpater there could inserts and deletes that need to be done also. only two letters away from being an asset Re: Need help with Insert, Delete and update commands in VB.NET davos14-May-09 2:38 davos1 4-May-09 2:38  I tried ticking the "Generate Insert, Update and Delete statements" and nothing happened. How can I generate the commands? Re: Need help with Insert, Delete and update commands in VB.NET Not Active4-May-09 2:50 Not Active 4-May-09 2:50  Create them youself. If you have complex statements the autogenerated ones aren't usually as efficient as ones you would create manually. Besides that, you should be using stored procs rather than manual sql statements. only two letters away from being an asset Re: Need help with Insert, Delete and update commands in VB.NET davos14-May-09 2:56 davos1 4-May-09 2:56  How would I create them?
