Hi! I have some problem relating saving datetime variable in SQL Server from C#.net application. i use Datetime.ToShortDateString() while sending parameter to Database. now the format of resulting string depends upon the regional settings of windows and SQL server takes M/dd/yyyy format or ISO format yyyymmdd. I want my application to be independent of regional settings. so i want whatever the regional setting is i should send to DB after converting to M/dd/yyyy format. For this purpose i wanted to override DateTime.ToShortDateString() but DateTime is a sealed class. So what should i Do??? any suggestions??

HI.. i have made a small application which hides folders by renaming them by using clsids. clsids are concatenated by folder names and different attributes are added to the folder automatically. i use class id for locking folder. The big problem faced by me is that usually these clasids are not visible to user and aparently he doesn't know that clsid is used. but unfortunately in some versions of windowsXP and specifically in windowsXP server2003, when i renamed the folder its class id is fully shown along with its name?? why is it so?? i tried to use different options from Tools->Folder Options->view menu but not successfull. plz help me what to do????

i am using a combobox and a textbox control. text box behaviour depends upon selected value of combobox. These properties of combo box are assingned. AutoComplete = true; AutoCompleteMode = SuggestAppend; AutoCompleteSource = CustomSource AutoDropDown = true; Further more .net 2.0 is under usage with visual Studios 2005. in combobox_TextChanged() event i have assigned some value to textbox control. now i want that when user is typing over the combo box then as he types first letter the TextChanged() event is triggered and my textbox values changes accordingly. i want to control it some how so that when user ends typing only then my textbox values are changed. I tried to control it through combobox.selectionStart and combobox.selectionLength properties but thay always give 0 values. So how should achieve my goal?? Furthermore when user start typing over combobox and in case selection changes then no key event is trigered (i.e keyPress(), keyUp() or keyDown() events)but it selection doesn't changes only then keyUP() event is trigered. Moreover event of combobox_SelectionChangeCommitted()is also tested and it is not triggered when user types on combobox. Any suggestions?

hi! i have used this chunk of code for taking only positive decimal and interger values, it worked successfully for me. you can modify it according to your need. it is basically keypress event of textbox... private void onKeyPress(object sender, KeyPressEventArgs e) { char[] myNum = new char[12] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '\b','.' }; bool blnNumFnd = false; //for keeping track of decimal foreach (char c in myNum) { if (e.KeyChar == myNum[11]) { String txt = ((TextBox)sender).Text; if (!txt.Contains(".")) { blnNumFnd = true; //means its decimal value and user can't enter another decimal again! break; } } else if (e.KeyChar == c) { blnNumFnd = true; break; } } if (!blnNumFnd) e.KeyChar = '\0'; } hope it will work for you!

sure here it is: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ListBox1.Items.Add("good") ListBox1.Items.Add("bad") End Sub then here is 2nd chunk of code: Private Sub ListBox1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseClick DirectCast(sender, ListBox).SelectedItem.Enable = False End Sub hope you'll get to the problem.

Thanks..

The sender passed it should be the listbox. You should be able to cast the sender as a listbox and get the selectedindex. Use the selected index to get the listitem and set the enabled = false.

but its not possible because there is no class in whichi save that item further there wasn't any need to use selectedindex for selecting item but i can use selecteditem for such purpose.. so the origanl question is as it is...

Hi i am working in VB.net using .net 2.0. i have a requirment to disable a listbox control's single item ....i searched msdn which says.. "You can disable an item in a list box or combo box by adding a single backslash to the beginning of the expression. " i tied the following code ListBox1.Items.Add("good") ListBox1.Items.Add("\bad") but it didn't worked and "bad" did not appeared disabled.. dispite this my requirement is to disable an item when mouse double click event occurs... hope someone will come with solution

i am using a treeView control in which i want to display image against its every node. the images are placed in project directiory's \bin\release folder. now the tree is popupulated when the form is loaded i.e the statements of populating the tree are after calling InitializeComponent(); in the constructor of new form. at first time when i come 2 this form (calling it against the NEXT button of a prevous form) then no problems occur and the images are loaded without any complication but when i go back to a previous form and come back to this form through same path and using same NEXT button then fileNotFound exeception occurs at this line Image img = Image.FromFile("pic1.jpg"); but previously images were displayed successfully...! i am facing same problem when i rightclick and create a contextMenu against a node. images are displayed against each optin of contextMenu successfully at first but when i click some option of contextMenu then work n then rightclick same node then the same exeception fileNotFound occurs(while populating ContextMenu) at same sort of lines... further more if i am debugging the project then these fileNotFoundException occurs even for the first time when i populate the tree.but when i run the project no error comes for the first time and the images are loaded successfully....but only for first time..! i canot understand where the problem lies??

May God help u solv ur problems as well,thx in advance!!

you have to put following code behind the button against which you want to... this.hide(); NewForm nw = new NewForm(); nw.ShowDialog(); nw.Activate(); nw.Close(); it is a well experienced code and u should not face any problems.hope your question is answered! regards
