As I want to shift from one IP address to another IP address with application the effect should take place without rebooting the system. Thanks in advance. Raju Re: using VB.Net How to Change Local Machine IP Address without rebooting the machine Dave Kreskowiak31-Oct-06 6:37 Dave Kreskowiak 31-Oct-06 6:37  You'll have to use WMI and the Win32_NetworkAdapterConfiguration[^]to change the IP Address. Also, there is no guarantee that you won't have to reboot the machine.

Christian Graus31-Oct-06 1:29 Christian Graus 31-Oct-06 1:29  You don't want a picturebox, I am often astounded at the things people expect those to do. You want to write your own control to do this. That is, no control will do what you want.

Here's the question: i have cbRestname : combobox txtResttel : textbox txtRestLoc : textbox i have a database named Restaurants on MS Access and i have a table named Restaurants_avail where i have rest_name, Rest_loc, rest_tel and rest_type I have already connected the db to my application and have been able to populate the combobox with the rest_name field. My question is this....when i scroll during runtime through the combobox, i want the textboxes to be filled with the location field and the telephone field....how am i going to do that??? I need some code pls thank you very much for your time lukis Re: combobox question ChandraRam30-Oct-06 22:45 ChandraRam 30-Oct-06 22:45  Have you tried writing code in the Click or Change event of the combo box? You could query the database based on the combo box value and set the text boxes. Hope this helps Chandra Re: combobox question lukisf30-Oct-06 23:50 lukisf 30-Oct-06 23:50  yes but my prob is this. i don't know the code to put in the selectedindexchanged i'm new to comboboxes so if you could supply me with some code it would be very helpful. thank you for your prompt response luke Re: combobox question ChandraRam31-Oct-06 0:00 ChandraRam 31-Oct-06 0:00  What version of VB are you using? Chandra Re: combobox question lukisf31-Oct-06 0:07 lukisf 31-Oct-06 0:07  2003 thanks luke Re: combobox question lukis31-Oct-06 21:19 lukis 31-Oct-06 21:19  any news luke Re: combobox question ChandraRam31-Oct-06 23:02 ChandraRam 31-Oct-06 23:02  Hi I am sorry, but I dont know the exact syntax in VB 2003. I think you will need to open a cursor (a record set?) from the database that corresponds to the selection in the combo box and fill in the text boxes from values in that cursor. Hope this helps Chandra Re: combobox question lukis1-Nov-06 2:16 lukis 1-Nov-06 2:16  i guess vb 2005 is almost the same. if you have any code regarding vb2005 i think i can manage to try something out luke Re: combobox question lukisf1-Nov-06 22:08 lukisf 1-Nov-06 22:08  guys/gals, i found this on thecodeproject but it's in C#. www.codeproject.com/csharp/combobox.asp I want something exactly the same but obviously in vb.net. if you could translate it in vb then i could use my data to arrange it but at least i get an idea of how this is thanks luke Re: combobox question lukisf3-Nov-06 4:57 lukisf 3-Nov-06 4:57  guys imagine i have this table Rest_type Rest_name Tel Location ----------- ------------ --- ---------- ala carte del pinto 2345546 Dublin pizzeria francesco's 3455667 Rome now i have a form with a combobox (cbRests), and 2 textboxes (txtType, txtTel) i have been able to include the Rest_name in the combobox but i need to fill in the textboxes with the relevant info...ex when i select del pinto from the combobox, i want the textboxes to display ala carte and 2345546....how can i do that......in code please as i have no idea on how to do that.... thank you very much...your help is very much needed here luke Re: combobox question Janani Divya30-Oct-06 23:06 Janani Divya 30-Oct-06 23:06  Use combo box selected event changed to fill the text boxes.

You can also derive your own combobox cell and return text "Loading..." in Cell.GetValue function while the SELECT statement is running at background. When it is finished, call to InvalidateCell and populate combobox with db results. ----------------- Solo hay 10 tipos de personas, las que saben binario y las que no How to add one more extra column something like "Notes" To an existing datagrid with some columns Durgamalli30-Oct-06 20:58 Durgamalli 30-Oct-06 20:58  Hi all, I need to add one more column "notes" to the datagrid which already has aound 10 columns.I know how to do it in asp.net.In asp.net we go to the property builder and add columns to the datgrid.But in vb.net is there anyway to add one more column to the existing datagrid..Please help me as its a bit urgent.

Be sure datagrid is not linked with any DataSource (add linked columns with column property --> "DataProperty". If the dg is linked, unlink, add column and link again. ----------------- Solo hay 10 tipos de personas, las que saben binario y las que no How to add one more extra column To an existing datagrid with some columns Durgamalli30-Oct-06 20:58 Durgamalli 30-Oct-06 20:58  Hi all, I need to add one more column "notes" to the datagrid which already has aound 10 columns.I know how to do it in asp.net.In asp.net we go to the property builder and add columns to the datgrid.But in vb.net is there anyway to add one more column to the existing datagrid..Please help me as its a bit urgent.
