Edit functionalities in Combobox atulagarwal5615-Jul-07 19:34 atulagarwal56 15-Jul-07 19:34  Hello there, Can anyone guide how to implement the regular cut/copy/paste functionalities in the windows forms combobox control? I am surprised to note that these are not present by default! I have been able to implement copy and cut for the selected text, but Paste still remains an issue as I am not able to know the position on the combobox where I should paste from the clipboard. Any help is greatly appreciated.

Even I am surprised, why didnt you find that? FYI, it is there. Re: Edit functionalities in Combobox atulagarwal5617-Jul-07 8:24 atulagarwal56 17-Jul-07 8:24  HI, I agree that its present. But guess I forgot to mention that I am using MDI forms and the same functionality is missing the moment you add a combobox to a child form. How do we solve this? Thanks and regards, ATUL Re: Edit functionalities in Combobox Mike Dimmick16-Jul-07 6:11 Mike Dimmick 16-Jul-07 6:11  I'm assuming that you're using a DropDownList-style combo box, because the edit box of the DropDown style already implements cut/copy/paste. To select a particular string, use the FindString/FindStringExact methods to find the string, and set the SelectedIndex property to the returned value to select it. Stability. What an interesting concept. -- Chris Maunder Master Detail Brady Kelly13-Jul-07 5:09 Brady Kelly 13-Jul-07 5:09  How do I link data bound detail fields on a form to data bound master fields? I'm using the default setup produced by dragging fields onto the form from the Data Sources window, so I have two BindingSource objects, one for detail and one for master. The two tables are linked by a relation in the DataSet. Datagridview phantanagu12-Jul-07 23:39 phantanagu 12-Jul-07 23:39  Hello eveybody! I have a small question need your help. My datagridview is bound with a dataset contains tblProduct table. A combox allows users choose a Product(B3700, NAPPLE 3'1, NAPPLE 3'2,...) If I filter like this tblProductBingdingSource.Filter = "Product = 'B3700'" . It works well If I repeat tblProductBingdingSource.Filter = "Product = 'NAPPLE 3'2'" , it fails to work because of existence of the quote mark. If I replace string "Product = 'NAPPLE 3'2'" with string "Product like 'NAPPLE 3%'", my grid will have this list of unexpected products such as NAPPLE 3'1, NAPPEL 3'2, NAPPLE 3'3,so on. When the users choose a value from combobox such as NAPPLE 3'2, I only have an only product, NAPPLE 3'2. Please help me correct the filtering string. I know the filtering string "Product like 'NAPPLE 3%2'" but the string is not general for all. Thanks in advance Sorry about my English. It seem to be a solution or an answer. Re: Datagridview SHatchard13-Jul-07 1:21 SHatchard 13-Jul-07 1:21  You can replace the single quote with two of them which means that it will work, so the search term would be "Product='NAPPLE 3''2'''" Give it a try and post back if you need any help how i can make that cursor will not show at all in read only text box? tomertro11-Jul-07 20:00 tomertro 11-Jul-07 20:00  Hi I have a text box with the following properties: Enabled=true,readonly=true.

Luc Pattyn12-Jul-07 0:23 Luc Pattyn 12-Jul-07 0:23  if you want to read it, you may also want to be able to copy (part of) its contents, so having a cursor may be good.

Tomer Trojman. Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue. varshavmane11-Jul-07 19:40 varshavmane 11-Jul-07 19:40  Hi All, I am getting this error when I am adding user control in the form, Please me in solving this problem. Thanks in advance. Re: Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue. RepliCrux11-Jul-07 19:48 RepliCrux 11-Jul-07 19:48  In your user control there is a variable called emSize, -- Either you are setting the value as 0 (and it should not be) -- OR there is some calculation going on in the code, which is resulting the value of emSize to be 0 (which ofcourse should not be) If that does not help, post it the usercontrol code. Cheers. Re: Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue. varshavmane11-Jul-07 20:16 varshavmane 11-Jul-07 20:16  No I have not use emSize variable anywhere. The user controls is date control and code is: Me.BackColor = g_FormBackColor Dim obj As Object For Each obj In Me.Controls If TypeOf obj Is TextBox Then obj.backcolor = g_TxtBackColor 'clrtxtbackcolor 'color.lightgray obj.forecolor = g_TxtForeColor 'clrtxtforecolor 'color.blue obj.font = New Font(g_strTxtFontName, g_intTxtFontSize, FontStyle.Regular) '"courier new" 'obj.borderstyle = borderstyle.fixedsingle End If If TypeOf obj Is Label Then obj.font = New Font("", g_intLblFontSize, FontStyle.Bold) End If Next My code is working fine if I comment this code. Please help me...Thanks in advance... Re: Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue. RepliCrux11-Jul-07 20:36 RepliCrux 11-Jul-07 20:36  Hi, I did a quick search, looks like emSize has to do with System.Single, U are right. don't know the exact reason why the code is falling over, but you can find a way out for sure. may be 'obj.borderstyle = borderstyle.fixedsingle is the reason. goodluck Re: Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue. Luc Pattyn12-Jul-07 0:27 Luc Pattyn 12-Jul-07 0:27  Hi, in your Font constructor the second parameter (your g_intTxtFontSize) specifies the "emSize" of the font. Give it a reasonable value before instantiating a font with it.
