Dynamically Remove Method Calls At Runtime?
Jan 24, 2011What's the best way to dynamically remove method calls at runtime? Essentially what I'd like to do is pass a parameter to my application. Let's call the parameter level. Depending on the value of level, I'd like to essentially remove all the calls that have higher levels. I have the following but was wondering if there were a simpler/cleaner way to remove the calls:
Ideally I'd really like to write something like:
Log5("message")
And just have Log5 work or not call if it doesn't exist. My goal is to actually remove the call. The overhead for calling level 5 logs that test and return is fairly high and I rarely use it.
Module Module1
Delegate Sub Log(ByVal message As String)
Public Log1 As Log = Nothing
Public Log2 As Log = Nothing

Remove All Eventhandler From Specific Event Of Control During Runtime?
Dec 29, 2009I do have a customized treeview which inherits from treeview. The customized treeview offers - amongst other - the functionality to automatically check/uncheck the child and parent nodes according to the selected node.To do so, I use (or mabye abuse?) the AfterCheck-event of the treeview in the class where the inherited treeview is customized. Code looks like that (Submethods not included):
[code]...
I temporarily remove the AfterCheck-Event in the event-procedure to avoid it getting fired when I programmatically check/uncheck the checkboxes of the treeview. Works fine so far, only problem I see: if another programmer wants to use the customized tree view and tries to make use of the After-Check-Event, he'll get caught in an infinit loop, because his own After-Check-Event (he added himself to the treeview) was not removed and keeps on firing every time a checkbox is automatically checked/unchecked.
How can I remove ALL methods linked to AfterCheck-Event without knowing which method someone added to the treeview-control? My guess is to use reflection and to get the underlying delegate of the AfterCheck-Event by using the .GetInvocationList somehow - but I was not able to make it work.

I should be able to get result back as long as there's a match in the parameters.

Asp.net - Sort DataAdapter Alphabetically ?
Nov 30, 2010This should be a fairly simple one. I am creating a dataset which will contain a description field which I would like to sort by. The reason I want to sort the dataadapter and not in my SQL is that I am already ordering by the results that have a particular value.My SQL looks like this:
SELECT pif_desc, pif_fund, psf_end, (CASE WHEN SUM(pmi_units) IS Null THEN 0 ELSE SUM(pmi_units) END) As fundunits
FROM tbl_mem INNER JOIN tbl_sfunds[code]....
I want to sort the datarows is ds.tables(0) by pif_desc but still have the rows with fundunits > 0 listed first. how I can achieve the correct ordering.
DataAdapter Does Not Update A Record?

DataAdapter Not Writing Updates
Sep 29, 2009I'm trying to create a form that uses controls that are bound at runtime. All the data objects are declared at the form level. The Select statement includes the two fields that make up the PK form the table. The Owing_Company data displays in the bound control. I can change the text and in Save_Click the RowState is Modified and Row!Owning_company has the changed data. DsForm.HasChanges is False. A simple call in Save_Click daForm.Update(dsForm) does not change the DB. If I update the Row!Owning_Company in code dsForm.HasChanges is now true and daForm.Update changes the data. What am I missing that allows changes made via the bound control to modify the DataSet?
