问题描述

大家好，

在我的应用程序中，我执行2个任务：

[1]显示cmbrno_click上的所有值（）



[2]显示cmbfulnm_lostfocus上的所有值（）



和cmbrno样式是2下拉列表。

Hello all,
Here in my application I am performing 2 tasks:
[1]display all values on cmbrno_click()

[2]display all values on cmbfulnm_lostfocus()

and cmbrno style is 2-dropdown list.

Private Sub CmbFulNM_LostFocus()
RES.Open "student_record_database",CON,adOpenDynamic,adLockOptimistic,adCmdTable

For i = 0 To RES.RecordCount - 1              
            CmbRNO.Text = RES!ROLLNO // at this line control goes to the cmbrno_click event which is having same part of coding and executes that also.

            TxtFNM.Text = RES!FIRST_NAME  //error like: item not fount in  corresponding ordinal

            TxtMIDNM.Text = RES!MIDDLE_NAME
            TxtLNM.Text = RES!LAST_NAME
            Text5.Text = RES!CONTACT
            Text6.Text = RES!CONTACT1
            Text7.Text = RES!CONTACT2
            TxtADDR.Text = RES!ADDRESS
            COMBO1.Text = RES!GRADE
            CmbDiv.Text = RES!DIV
            CmbBG.Text = RES!BLOOD_GROUP
If CmbRNO.ListCount > 0 Then CmbRNO.ListIndex = i   
Next i
