The below Code is written inside the Timer Tick event. It works fine as long as the Time and Date are not same. When the Time and Date are same it only displays 1 message. How can I show multiple message for the same date and Time ? I think this can be done If I create different instances for a form. But I don't know how many same time and Date will be there in the database. So I can't do that.
Dim frm As New frmMessage
Dim nowDate As String = String.Format("{0:M/d/yyyy}", DateTime.Now)
Dim nowTime As String = String.Format("{0:h:mm tt}", DateTime.Now)

I have a program with 3 forms; each has a different role behind them. Form 1 loads when the program executes and the other 2 load by clicking on buttons from form 1. I would like to implement a multithreaded approach where even after clicking on form2 and form 3 I can still execute other form 1 options while form2 and form 3 contents execute. I read through some tutorials and still not to sure how to implement. I figured I need to create instances of the forms 2 and 3 but how to call the threads and control them? I did try a simple one and had some error concerning delegates.
View 4 RepliesI have a problem that can be best solved with LINQ. I have a class that has 2 properties of which 1 is a single. I have a collection of that class and I need to select the instance with the highest single value.[code]I'm having a hard time explaining this even this is a simple task. Please ask if you don't understand.In addition to my original question, How would I create a collection containing the 5 highest Instances.

Is that possible to create a class in vb.net that is not in the default namespace of the project?
for example, say you have a project call sample1, then automatially IDE will have everything default to the Sample1 as your namespace root rather than under global, which is find for most case.but I want to create some classes that is directly under global namespace
I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?
View 1 RepliesI have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

2. FunctionLayer -deals with Common Operations which get results from DataLayer and return results to Forms.3. User - deals with User. (For Reusing the User Class in other projects, i have separated this class)Here in Class2 - I have an instance of Class1( ie., DataLayer) for DB Operations.imilarly in Class3- I have an instance of Class1( ie., DataLayer) for DB Operations.Now in my form, If i create Instance of Class2. But When I need user functionality in this form, I have to create an instance of Class3 to this form.
View 6 RepliesOne feature of C# compiler is that namespace declaration by default follows the folder name structure in the project. By e.g. you have MyProject1MyDrawing and inside you create a class MyPoint the namespace for MyPoint will be MyProject1.MyDrawing
In VB I cant see any namespace declaration(apparently it implicitly 'inherits' the project(MyProject1) namespace). If I create a MyPoint and MyLine clases in the MyDrawing folder I need to surround each of created classes with "Namespace MyProject1.MyDrawing"..."End Namespace".
Is it possible to automatically name the namespaces like in C# by the folder name?

I am having a namespace extension implemented, which is visible in "MY Computer". I want to write automated test cases to browse through the same. I am able to open the explorer window till the namespace extension. as -
Process.Start("explorer.exe", "shell:::{CLSID of my namespace }")
next I want to search for a particular folder name inside the window opened. For example if i give input as "temp", then my mouse should move to "temp" folder in the namespace explorer window. then I double click on the mouse's current position and enter that folder. next i give input as "doc1.doc", then my mouse should be able to locate & move to "doc1.doc" file. Also getDirectory or GetFile etc APIs won't work because I don't have a standard drive associated with my namespace & don't have a relative path either.
I work with VB6 SP6 under windows XP SP3.I' ve created a user control activeX. When I create some instance with the command : Form1. Controls. Add I have this error : "Error '50003' Unspecified error" if I create too many instances.
For Index = 0 To UBound(obj) Set obj(Index) = Form1.Controls.Add("MyUserCtrl.MyClass", "Label" & (Index)) obj(Index).Visible = True next index
I seem to be drawing a blank. I'd like to create a "shared" variable that is shared with all instances of a class but not classes that inherit from it. For example.Class A: Shared list As New List(Of String): list.Add("A")
Class B Inherits A: list.Add("B")Class C Inherits B: list.Add("C")The end result I'd like is that any instance of A has just A in the list. Any instance of B has A and B in the list. Any instance of C has A, B, and C in the list. I can accomplish it by creating Instance variables, but I have to construct the list for each instance of a class. I'd like to construct it once for a specific point in the Hierarchy and then share it accross other instances of that class.
When setting up the Ajax Control Toolkit's AutoComplete control, it creates an utoComplete.asmx and a AutoComplete.vb file. The AutoComplete.vb file automatically ends up in the App_Code folder. I was hoping to move all of these styled-classes into a separate namespace, but the compiler simply does not dig it. Is this possible, or must it be within the presentation layer to access the "Web" related namespaces?

View 4 RepliesI am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False
