C# - Compare Datetime.Now With A Datetime Variable
Dec 27, 2010I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?

Extract Time Value From DateTime Variable?
Oct 22, 2009I need to obtain time values from a SQL DB. However, I was able to set the datatype for the respective column in the SQL table only to "datetime" as there is no "time" option in the dropdown list in the Visual Web Developer. Namely, I want to bind a Listbox control only to the time data (i.e. not to "dd-mm-yyyy hh:mm:ss"). I tried to convert the datetime values to string and then extract the last 9 chars that refer to time.Unfortunately, my attempts to do that with SubString have failed:
weekDays.DataTextField=Convert.ToString("Start").SubString(length("Start")-10,9)
where:
weekDays - ListBox

Use CType To Change An Object Variable "obj" To Custom Class That Reference Using A String Variable Like Obj.GetType.Name?
Feb 9, 2011The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

View 3 RepliesMatch A Certain DateTime Value With Current System DateTime
May 7, 2010I'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

View 3 Replies.net - Value Of Global Variable Won't Change
Dec 22, 2011I have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.
[code]....
Here is the entire source code:
Module Module1
Public strDataValue = frmTest.txtDataValue.Text
End Module
[code]....
Note: This is just a demonstration of a problem I'm having in a much larger program so the variable does have to be global.

Dynamically Change Variable Types?
May 10, 2010I'm trying to make an application to do mathematical equations, but I also want to implement error checking. So that if someone doesn't put anything in one of the fields the output textbox will say "Error".
But the problem is that I already declared the variables I used as a numeric value, in my case decimal.
So, when I make an if statement that says if inputbox1="" then outputbox1="Error" it doesn't work.
I think that in order to get this to work I would have to have it setup so that the variable that is exported to the text property of outputbox1 could switch between being declared as a decimal or string value based on what the user put into the textboxes. But I'm not sure how to go about this. Declaring the variables inside the if/elseif statements won't work because the variables need to be declared before they are calculated within my if/elseif statements.

During this 10 sexond pause I would like to change the value of Y. It needs to be changed only for this run, not a permanent change which can be done in the declaration.
