CPU Bug Tracing - Load Dll Dynamically
Mar 27, 2009
[Code]....
This is in a button click event, and when I click the button, the DllMax.DllMax form should be shown.[Problem]The DllMax.DllMax form is shown well, and after I close it, I found the CPU is from 0% to 20%.Don't quit the application, add Click button1 again, and close the form, the is from 20% to 40%.The CPU persentage is NOT added when the form is opened(I checked it carefully), but added just when the form is closed, and it will keep to 40%.I don't know what the CPU is doing? I want to know:1. Is there a method to find out what exactlly CPU is doing in my application?2. Why the CPU from 0% to 40% when I close the form?3. Why the CPU keep to 40% even I did the FormToShow.Dispose()?

I am trying to write some code that will allow me to dynamically load DLLs into my application, depending on an application setting. The idea is that the database to be accessed is set in the application settings and then this loads the appropriate DLL and assigns it to an instance of an interface for my application to access.
This is my code at the moment:
Dim SQLDataSource As ICRDataLayer
Dim ass As Assembly = Assembly. _
LoadFrom("M:MyProgsWebServiceDynamicAssemblyLoadingSQLServerinDebugSQLServer.dll")

I have a GUI that is processing data from our shop floor.In order to communicate with external programs, we are using MSMQ to process messages. Each interface we have to an external program, we are currently creating a class file with only properties,calling the class in the GUI, setting the properties, then sending the class object to MSMQ for processing.The class is serialized as an XML file, and the queue watcher can pick up the class, deserialize it process the messages without any problem.Currently we have identified three interfaces, developed the classes for them and this is working great.As more interfaces are identified moving forward, I would like to avoid having to add the classes to the GUI front end for each interface.I would like to create a DLL for each interface (again only with properties) that could be dynamically loaded and discover the properties for the class.The GUI could then set the properties for the class and process the message.One property each class will have is the name of the interface.This will be a readonly property that will the queue watcher know which interface to use. In order to make this dynamic, I could create some tables in our database that would contain the name of the interface and cross reference the properties in the DLL with parameters in the GUI. This way the GUI would only call one DLL that would be embedded in the GUI, it would call the database to get the parameters needed for the interface, match them from the GUI and create the message.
1.What is the best way to dynamically load DLL's using VB 2008?
2.Does this sound like a good proposal?
3.My intent is to have the GUI re-compiled as little as possible to minimize the impact on the shop floor when new interfaces are created.

I am implementing a tracing mechanism myself. Now what I'd like to know is what is the best way to implement this mechanism(I mean, the architecture).[code]But then I saw there is an TraceListener class that let's me implement Write and WriteLine methods. The big drawback is that both those methods allow only strings as arguments, and I'd want to be able to send a lot more info than strings. What should I do? Maybe my first ideia is the best?I do know there are a lot of tracing mechanisms like PostSharp and so, I'm just doing this for learning purposes!

i m trying to load the tabs dynamically.(Using AjaxToolKit). Firstly, when i hit button1 on pageload, it loads tab1() (works good) and when i hit button2, itloads up tab2() All these tabs are ascx pages. In tab1 i m loading WebUserControl.ascx. it works okay.
Issues:
1) When you runthe code, first click on button2, it doesn't load tab2 dynamicaly but it does when u hit button1 for the first time.
2) Repetitive clicking on button1 or button2 should load the same tabs next to eachother again and again but it doesn't
3) Thirdly, the main issue is that I m tryin to load another .ascx on loadtab2() which should have webparts in it. I should be able to load an another custom usercontrol into these web parts dynamically. But i m not able to do so.
Here is my code:
Default.aspx
<p>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</p>

there are two forms, form1 and form2. form1 has textboxes 10, the user can enter data in a specific number of textboxes: ie: 5 or 3, or etc.
then the user clicks a button, and based on the number of textboxes that he entered data on, form2 will load a number of texboxes: If the user filled 3 textboxes in form1, form2 will show 3 textboxes.

I'm trying to use System.Diagnostics to do some very basic logging. I figure I'd use what's in the box rather than taking on an extra dependency like Log4Net or EntLib.
I'm all set up, tracing is working wonderfully. Code snippet:
Trace.TraceInformation("Hello World")
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
[Code].....
That doesn't make sense to me: I just have to declare an instance of the BooleanSwicth to be able to manage (disable) tracing via the .config file? Should I like ... use ... the object somewhere?

I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.

I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.

I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.

I'm trying to do the following.I want to use a gridview to load a set of associated records dynamically based upon the input of the user.I want the gridview to have a checkbox to the left of the records and allow the user to use this to select records to remove. The gridview will have pages and will be sortable using the columns.I had this working using a delete button, but when I went to using the checkbox it stopped sorting.

I have a DataGridViewImageColumn that should display an image for only certain rows. After I bind a generic list of classes to my datagrid, I loop through each row and update the image cell with an image that is an embedded resource for the rows that require the image. This works great if the form has been fully loaded. However, when I attempt this on form load the image doesn't show up? I also can't perform simpler things such as changing the row background color on form load. Should I be performing this logic in a different event after form load?
For i As Integer = 0 To dgvRoles.Rows.Count - 1
Dim imageStream As System.IO.Stream = Nothing
imageStream = Me.GetType().Assembly.GetManifestResourceStream("MyApplication.Timer.png")

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!
