Addition problems

I am creating a currency converter that not only converts the currency it also adds the total amount converted together and displays it in US$. My problem is that when I enter an amount to be converted it adds it to my total converted box, but when I add another amount to be converted it replaces the first amount instead of adding them together. How can I fix this? Also, when I close the application I lose all the previous data. How can I save this? I've have heard "SaveSetting" but I don't know how to use it.
Thanks!!!

Post some code...

SaveSetting is easy

SaveSetting "AppName","SomeName","DataDescription", Data

ex:

Data = txtTotal.text

SaveSetting "ConverterApp","Settings","TotalConverted",Data

to get it back

Data = Getsetting("ConverterApp","Settings","TotalConverted","")

in getsetting the last entry is the 'Default' meaning if the field is not there in the registry..it will set it to this value...in this case nothing

I tried it, but it gives me an "invalid outside procedure" error.
Keep in mind that I don't really know what I am doing, and the book I have mentions nothing of "SaveSetting"
here is my code below if anyone wants to look.

Data = lblAmountSpent.Caption
SaveSetting "Currency Converter", "Settings", "TotalConverted", Data
Data = GetSetting("Currency Converter", "Settings", "TotalConverted", "")
Dim rate As Currency


Private Sub Command1_Click()
Text3.Text = Val(Text2.Text * rate)
Option6.Value = 0
lblAmountSpent.Caption = Format$(Text2.Text, "currency")
End Sub


Private Sub Option1_Click()
rate = 2170
If Option1.Value = 1 Then Text3.Text = rate * Text3.Text
cboLog.AddItem Option1.Caption & Text3.Text
End Sub
Private Sub Option2_Click()
rate = 2.19
If Option2.Value = 1 Then Text3.Text = rate * Text3.Text
End Sub

Private Sub Option3_Click()
rate = 7.35
If Option3.Value = 1 Then Text3.Text = rate * Text3.Text


End Sub

Private Sub Option4_Click()
rate = 0.68
If Option4.Value = 1 Then Text3.Text = rate * Text3.Text

End Sub

Private Sub Option5_Click()
rate = 1.12
If Option5.Value = 1 Then Text3.Text = rate * Text3.Text
End Sub

hmmm.. are you using VB6?

is it erroring on the Savesetting?

also...Dont use SaveSetting...then GetSetting right after that..

When you close the app (Form_unload) use the
SaveSetting to store the value

then in the Form_Load() event use the GetSetting to retrieve it.



try this...
start a new project...
add a command button

paste this code in

VB Code:

Private Sub Command1_Click()
MsgBox GetSetting("MyApp", "Startup", "Left", "")
 
End Sub
 
Private Sub Form_Load()
SaveSetting "MyApp", "Startup", "Left", 50
End Sub

then run it..and click the button..does it show 50?

It does say 50...I am using VB 6.
So what does "Left" mean?
Can I change "Left" to what I want it to save and return? Like if I want it to save and return the value of lblAmountSpent?
Thanks

i think i got your problem....

try this

VB Code:

Dim Data As String
Data = Cstr(lblAmountSpent.Caption ) 'use the Cstr() to make sure its a string
SaveSetting "Currency Converter", "Settings", "TotalConverted", Data

savesetting only allows a string to be entered...so that may be why it broke before...

I still get the same error message...Do you think I am putting the code in the wrong place? Also, If I use the SaveSetting will it help me keep a running total of amount converted. Now if I put in $600 dollars and convert it and then convert another $300 it will not add the two, it just replaces the first number. I attached my program files if you want to take a look...
Thanks for all you help so far!!!

add it to the combo box?

(I found the first problem...you have the code in the general declarations section)

Where should I put the code? Under the Command button or the AmountSpent label?

hang on..I see what your doing...

ok here... all fixed..and a few tweaks

a delete button to clear the total

and a formatted textbox to display the converted amounts nicley


you still have to finish adding to the combo box

thank you, I see what's happening now. Thanks for leaving the comments in there. I got the Converted amount and type to add in the combo box but there is no space between them. (ie Euro2436 instead of Euro 2436.
the i wrote is
cboLog.Additem Option1.Caption + text2.text

i tried to do it this way but i keep getting errors.
cboLog.Additem Option1.Caption + & " " & text2.text

I thought the &" "& would be a space.

But anyway thank you very much!!!

you were close.
never use + to concantinate (spelling?) (add) 2 strings together always use &

cboLog.Additem Option1.Caption & " " & text2.text

I removed the + from that line..that should work fine

Thanks, How would I set an error message to appear if the user does not have a currency type selected?
