• .NET Development insert into table from combobox (User selected)

  Hi All, Can Anybody help, I have a sql_2000 db which has two tables, I am using vs.net2005 (VB.net) as a front end. I have a form with a combobox1 on it, populated from table1.centre when the user makes a selection from the drop down list I would like the value selected to go into table2.centre field along with the other details submitted on the form. I can get the list of values to display but it doesnt seem to populate the table2.centre. I have probably done it wrong from the outset. I should also point out that I am a newbie and would greatly appreciate step by step help on this. Heres what ive done so far! on the form in design vie ...Show All

• Windows Forms How can I make a local attribute visible in Properties (designer) or the "items tab"

  Suppose I declare a local Collection object (by hand in the text editor of my part of the partial class). I want to be able to see it in the designer, either in the Properties window, or on the little bar below the form where you can drag things like DataSets onto. The reason I want it is so I can databind my collection to a bunch of text inputs, rather than having to do it by hand. So, how can I achieve it (and btw NO I don't want to make a custom class to be displayed in toolbox, because I don't want to create a separate instance of that collection, I want to use just this one local instance).   THa ...Show All

• Visual Studio 2008 (Pre-release) "yield enumerate"...

  (Slightly off-topic, but it at least deals with enumerations.) Lately, I've found myself using the following pattern: public IEnumerable<T> Foo(IEnumerable<T> values, IEnumerable<T> moreValues) {     foreach (T t in values)    {       yield return t;    }     foreach (T t in moreValues)    {       yield return t;    }     // more yielding }   For example, if I want to maintain the sanctity of values, but catenate another set of values (checksums, e ...Show All

• Visual C++ Can functions....

  ...be nested inside other functions No this is not possible - though you can define a local type which can have member functions. void f() { int i = 4; class X { public: X(int& i) : m_i(i) { } void Incr(int v) { m_i += v; } private: int& m_i; } x(i); x.Incr(4); } ...Show All

• Visual Basic 'nother new to .net question - Time Functions

  does VB.NET have a built in function or namespace to get the date in a "Star Date" style single number, like 54285.34 (prefered for quick storage)    If it does not, how about a function to add to a time or date looking for an easy way to figure out when x number of hours/mins/days/weeks/months/years/etc have passed from the time that was saved and if there is a quick way I really don't want to have to reinvent the clock so to speak... There is a built-in function for that, using the Date datatype as the input: http://msdn.microsoft.com/library/default.asp url=/library/en-us/vblr7/html/vafc ...Show All

• SQL Server ASPNET account permissions

  I am new to Reporting Services and still learning, but it is a very nice exciting program. I built a new Report and was experimenting with Grouping in reports and using the parameters. Now I would like to Deploy the report to the Report Server so I can use this report on our intranet, however I get the error that the ASPNET account does not have the proper permissions. I am sure that I need to set up ASPNET to have "write" abilities. What folder(s) do I need to make sure that ASPNET has this Or should I be looking elsewhere to set up the ASPNET account on the Report Server Thanks for the information. ...Show All

• Windows Forms SuspendLayout suspends what?

  Can anyone explain why SuspendLayout() does not delay the resizing and repositioning of the Panel control in this short, easy to follow code sample (which is all there is to the entire program)... /* this snippet calls SuspendLayout before changing Size and Location properties of the Window's program's only control, a panel. Then it calls Sleep(6000) as a debugging device to see if the panel is resized AFTER ResumeLayout is called (after Sleep) or before Sleep(6000) is called. The documentation for SuspendLayout (as I read it), indicates that the changes should be delayed till after the 6 second nap, bu ...Show All

• SQL Server Foreach Loop Container causes package to crash

  We have a problem with a SSIS package containing a Foreach Loop Container that causes the package to fail unpredictably. We are using a Foreach Loop Container to process records in a source table one by one. We do this by executing a SQL statement on the source table, putting the resultset in a package variable and using that variable as an ADO object source variable in a Foreach Loop Container. In that container, we do four things: 1) copy the record we want to process into a temporary table, 2) run a dataflow task on that temporary table to actually process the record, 3) truncate the temporary table filled in step 1 and 4) delete ...Show All

• Visual Studio Team System WITIMPORT: Cannot complete the operation. An unexpected error occurred.

  The subject describes the error I get on the client side. But the server Application Logs says that SQL Exception occurred. The exception Message says: Cannot declare more than 10000 local variables. This is occurring when I try to load a WI type Definition that has a <FIELD> with 559 <WHEN> elements followed by another field with 2190 <WHEN> elements. So far I've tried removing 500 out of the 2190 but obtained the same error messages... Is tehre a limit on the number of <WHEN> elements I can have in a WITD It was working great when I only had the first 559 on the previous field. Thanks in advance. ...Show All
