• Windows Forms Process preview window

  I am looking to create a preview window in a form that I have that will display a running process. It's much that same as the preview window when selecting a screensaver in Windows. Basically I want to have a preview button that will display the running process in a preview window on my form and then be able to adjust parameters and see the results of this on the process. Does anyone have any ideas on how to do this, just the getting the process to display in a preview window part. Thanks Hi one thing you could do is to use Performance Counters to get some data on the process http://msdn2.microsoft.com/en-us/library/system.diagnostics.performancecounter.aspx display that data in a screen..

• SQL Server Unable to retrieve the @@Error code in stored procedure

  Hi All, In my application on click of Delete button, actually I am not deleting the record. I am just updating the flag. But before updating the record I just want to know the dependency of the record ie. if the record I am deleting(internally updating) exists any where in the dependent tables, it should warn the user with message that it is available in the child table, so it can not be deleted. I want to check the dependency dynamically. For that I have written the following procedure. But it is updating in both cases. CREATE proc SProc_DeleteRecord @TableName varchar(50), @DeleteCondition nVarchar(200) As Begin Begin Transaction Declare @DelString nvarchar(4000) set @DelString = 'Delete from ' + @TableName + ' where ' + @DeleteCon ...Show All

• Visual Basic 2 forms..1 call show to 2..2 wants to add combobox to 1.. problem !

  Hello, I have programmed java before but i am new to VB.net.. so this is what has been going on.. Form 1 has a button and combobox. On button click.. Dim obj as new Form2() obj.ShowDialog() Form 2 pops up ! Form 2 has a button called add. on button(add) click.. Dim obj2 as new Form1() obj2.ComboBox1.Items.Add("Hello") And nothing works I wonder why Instead of creating a new Form1() inside form2, try passing Form1 to the constructor of Form2: Dim obj as new Form2(Me) Inside the constructor, store the form in a member variable. Then on the button click, use the reference that you stored to add an item to the combobox. Sub New( x as Form1 ) Me.form1 = x On button(add) click Me.form1.C ...Show All

• Windows Forms Row disappearance in DGVs

  I posted a topic in Windows Forms General about this recently, but I've since learned a bit more about the problem and figured this was a more appropriate section. Anyway... I've got a problem with datagridviews in a tabbed application I'm working on. Now - this doesn't seem to be related to DataErrors at all, because I handle the DataError event by popping up an informational message box, and I'm not seeing that box or the dead datagridview that results from the errors. Originally, I thought I was seeing this problem when I would switch away from the tab with a set of lists and an update would come in for a list that wasn't on the currently displayed tab. Now I'm seeing that actually, nothing has to happen. If you switch tabs and sw ...Show All

• Visual C++ C1091 string too long, getting around it

  Is there an easy way to get around the limit of 65535 bytes for a string I'm moving my code to Visual C++, but I don't want to make unnecessary changes to it. Is there a compiler switch to change the limit Why not No, but you can break the string up into chunks and manage it somehow during runtime (either by concatentating or just keeping the array of chunks as is.) Or you can place the string in a resource and use LoadResource on it. ...Show All

• .NET Development Primary Key in XML Schema.

  I have to create a large number of tables in SQLEXPRESS. I set up one of them manually. I figured the next thing for me to do is to create an XML Schema. I used an MS XML notepad and another schema for a similar table but from a VFP database as a template. I do not know how to set up primary key on one field . The notepad designer does not seem to provide any prompts in its IntelliSense dropdown menu. It is the first field of the table, type int. This is how it looks in the schema file: <xsd:sequence> <xsd:element name="univRec_id"> <xsd:simpleType> <xsd:restriction base="xsd:int"> <xsd:maxLength value="8" /> </xsd:restriction> ...Show All

• Software Development for Windows Vista System.Transactions and MSDTC

  I've recently tried using System.Transactions.TransactionScope to handle my transactions. Although it's very handy and simple to use in my business layer, i cannot get the code to run unless the Distributed Transaction Coordinator service is running on my pc. (SQL Server 2005 is running locally so i can test on a local version of our database) My question is: why does this service need to run if all i'm trying to do should only require a standard Transaction, not a distributed one Is my transaction being promoted (and thus suffering a perf hit) This is the codeblock where i'm using the scope: Dim scope As Transactions.TransactionScope = New Transactions.TransactionScope Dim newname, oldname As String Dim sjabloon ...Show All

Despite that I still can't connect remotely to the AS server.
