I need to run an If Statement that will check a few conditions.
Basically I want to get it to check a value held in a variable "Temperature" and if the value is within "1" eaither way i.e. +-1 of the value held within the variable to then to output a text string to Label200.Text Else if the condition is not met then out put another text string to Label200.Text.
Example:
Say if Temperature value held in the variable Temperature is 8.5 the if statement checks to see if the DewPoint value is "between" +-1 of the temperature value. i.e. 7.5 to 9.5 as well as the value in Humidity is equal to or greater than 90 and Pressure is Less than or Equal to 1013.25 then the conditon is met, else the conditon is not met.
I have put some code together below in NotePad++ to see if what I am trying to do is the correct way to go about it (note I have not yet tried this code in VB.NET as I don't have it at work).
pass comment on the code and if it is wrong explain what I should do to get it to work.
Dim DewPoint as Single
Dim Temperature as Single
Dim Humidity as Single

I am a C# programmer but dabbling in VB.Net because everybody else in my team uses it. In the interests of professional development I would like to shrink the following If... Else... statement.

item.WhenUpdated = Nothing
Else
item.WhenUpdated = cmd.Parameters("@whenUpdated").Value
End If
my program is "live" and my customer has troubles because it doesn't functioning as well as it should.I don't know what happen, did I changed something or not but suddenly data won't save to database from newly created forms. Beside this form I have additional 20 forms and everything is working like a charm and I use same code logic to save data to database. I tried to find myself what could be the reason, check by entering data directly to database table (works fine), check insert statement of dataset table (seems fine, too) and everything I could imagine. But now I ran out of ideas and I had to ask here.
Also, I added 3 fields to database table (nvarchar, int and decimal). All 3 of them allow nulls. I changed dataset and data entry form and now data won't insert if I dont enter values to int and decimal fields. Also, this decimal field doesn't accept 0 value if enter but if I assign value 0 from the code than it is ok. I'm not sure if I somehow changed concurrency and somewhere. I tried to find where I can change it but I couldn't find it. I use Visual Studio 2008 and Sql Server 2005 Express. Language vb.net.
How would I go about writing an IF statement that would check for letters? Something like:
IF field IS NOT Int THEN
Response.Write "WRONG!"
ELSE
Response.Write "OK"
END IF

View 1 RepliesIs it possible to define my list of strings like in 'good old' VB60, to use only on ebyte of memory for each character? .NET always seems to store any string as unicode, which doubles the required memory. The case is that I have a huge list of strings, all of the same size. It is about 50.000.000 items, 12 characters each. You can imagine I am running out of memory in no time. I tried converting them to arrays-of-bytes but in that case I loose the possibility to perform a "LIKE" statement in a FOR-EACH loop to check for a specific item.

View 2 RepliesI am practicing abit with For Loops. My code works fine which i am very happy about. I have now moved on to inserting an IF statement. I want the IF statement to check if my textbox1 and textbox2 are blank and if they are to notify the user that they must insert a value. I thought this would be quite easy to do however i think i was again ignorant to the coding! See below.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim answer As Integer

I want to concentrate on the IF statement only as the For loop is working just as it should. When i run the program and leave both textboxes blank and hit the button i receive an error saying 'Conversion from string "" to type 'Integer' is not valid.'
