sorry my bad, errorprovider pala gamit mo.

  For Each objControl In Me.Controls
            If TypeOf objControl Is TextBox Then
                Dim objTextbox As TextBox = objControl

                If objTextbox.Text = Nothing Then
                    ErrorProvider1.SetError(objTextbox, "Fatal Error")
                Else
                    ErrorProvider1.SetError(objTextbox, Nothing)
                End If
            End If
        Next

replace this For Each objControl In Me.Controls with For Each objControl In Group2.Controls

lagay mo sa dalawang loop

for each objControl as control in me.controls
  if typeof objControl is groupbox then
    dim objGroup as groupbox = objControl
     for each objTextbox as control in objGroup.controls
       'yung code kanina resumes here
     next
  end if
next

 

[Gamecore]

thanks talaga sir


ito lang ayaw ko , katakot takot na validations

ehhe

 

[maskio]

thanks talaga sir


ito lang ayaw ko , katakot takot na validations

ehhe

gumawa ka ng function for validation, tapos e add mo lang yung mga items na kelangan mo e validate. tapos yung function mo na ang mag hahandle.

lagi mo tandaan: we need to make our lives easy. hehehe.

mga sir help naman po about getting random data without duplication...penge naman po ng codes for vb.net... salamat in advance

 

[ericgmejia]

mga sir help naman po about getting random data without duplication...penge naman po ng codes for vb.net... salamat in advance

ang logic lang po nyan ay

1, generate random, add to list
2, generate next random,
3, check if exist on the list,
4, add if not exist
5, return to 2


ganyan lang po, just check if the number exists on the list of generated numbers
add to the list if new number is not there pa

 

[maskio]

mga sir help naman po about getting random data without duplication...penge naman po ng codes for vb.net... salamat in advance

[mrteejay]

mga sir help naman po about getting random data without duplication...penge naman po ng codes for vb.net... salamat in advance

Try using GUID (Global Unique ID).

Cnu po may alam ng codes for Barcode Scanning sa vb.net. help nmn po thanks.

may device ka na ba?
kasi kung may device ka na malalaman mo na parang keyboard lang yan
wala ka gagawin kundi ilagay lang sa textbox ang focus at mag scan

no need ng sample

dont look for sample sa bawat code na gagawin nyo

ganito lang yan

display sa listview, alam mo na ba gawin?
meron samples sa page1 yata

meron event sa listview na click at double click

pag click or dbl click
get the key na gagamitin, usually yung TAG ng listviewitem or yung first column
run a function to read the database with this kind of query

"SELECT * FROM Table WHERE KeyField = '" & ListView1.SelectedItem.Tag & "'"

then makukuha mo yung record na merong ganun na text or tag

then pag nakuha mo pwede mo na ilagay maski saan

try mo i code using codes sa page1

Pano ko po magagawang dalawang klase ang mapipili dito

"SELECT * FROM tblInventory WHERE ProductID LIKE '%RBCO%' AND Quantity <= 300"

sa productID po may madaming pag pipilian like RBCA,RBBR,RBTA gusto ko po sana makasama si RBCO at RBCA tsaka po sa Quantity ni RBCA is 30
