View 1 RepliesThere is a varchar column in the database table in this format of military time 1230 or 1750 or 1320 and that field get populated into a gridview in asp. I need to convert that string to standard time. I have tried the DateFormatString and nothing seems to work.
the asp is
<asp:BoundColumn DataField="ScanTime" SortExpression="ScanTime" ReadOnly="True"
HeaderText="Scan Time" DataFormatString="{0:hh}:{0:mm} {tt}">
<ItemStyle Width="80px"></ItemStyle>
</asp:BoundColumn>
that DateFormatString causes Input string was not in a correct format. error.
I have tried combinations of hh:mm and things like that but since its a varchar I think its failing

View 1 RepliesI usually use standard button and do the settings like causevalidation etc if required.
i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.
so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.
I'm new but will most certainly be hanging around and maybe even answer some posts in other sections. I have the following issue: I have a vb.net web page that places data into an access database. If I leave one of the fieldS blank, (even though Access has a default value of '0' instead of null) when I click to view the results in another page, the page fails with an error.
"System.InvalidOperationException: The provider could not determine the String value. For example, the row was just created, the default for the String column was not available, and the consumer had not yet set a new String value. etc etc" IF I put any figure in the blank field, even if it's 0, the page functions and works. Baffling. So, the data input page really needs to check, 'if nothing has been entered, automatically append the database with 0. Here's some of the page code: (Standard Record Insertion Wizard within DW cs3, plus Validation)

I am trying to add a TabPage containing a UserControl to a TabControl at runtime, because the number of TabPages to add are determined at runtime.
The UserControl (objDataInfo) is just two Textboxes, two labels and two Radiobuttons, nothing too exciting...
The TextBoxes have their Anchor properties set to Left, Up, Right so they scale with the width of the usercontrol.
The TabPages are added in the constructor of the form, which takes the number of tabpages to create (n) as an argument:
vb.net
Dim cList As List(Of objDataInfo)
Public Sub New(ByVal n As Integer)
[Code]....
So... How can I get the standard BackColor of a standard TabPage?
(I tried leaving out the usercontrol all-together, but the TabPage still has a gray background...)

What is the standard method for accessing back end data, which logon should you use? For example we have applications that require the user to login but then use an admin account to access the data from the backend.But there are also applications that require the user to login and use those credentials to access the backend data.We are in the process of creating an application that will require the user to login and would like to implement the more common method(standard practice) of accessing data.If there are alternatives those are also welcome.This will be made in ASP.Net 3.5 or higher and may include Windows Applications(VB.Net) as well.I dont want to have two sets of credentials. What I am asking is which credentials are normally used to access the Database. For example one one application may access 2 or more database's. Now would you use the same credentials they used to login to the application or would you use the admin account to access the data?Maybe this should be a seperate question but if I ended up using integrated security to access the database would the user be able to simply connect to the database using his AD account? Either through an ODBC connection and MS Access or equiv.
View 2 RepliesI haven't done any VB coding since school (15 years ago) but currently have a need to run what "sounds" a fairly simple app at work. I'm hoping some of you might be able to give me some pointers as to whether or not my idea is possible, and if it is, how best to approach it.
I work for a company where we send a number of standard emails to potential clients asking them to contribute to our magazine . if no response we then send a number of follow up emails. each and every time I send a new email to a new prospect I'm editing one of our template emails, putting their name and email address into outlook and manually sending emails. Then for every reminder I'm going back into outlook, clicking reply all and then c&p'ing our second or third reminder emails in each and every time. needless to say at least 2-3 hours of my day are spent editing and resending the same emails on outlook.

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

I have the following code to open a webpage:
Dim IE As Object
Dim x As Integer
Dim c As Variant
[code]....
The page that opens is in xml and in that xml there is the "page_count" that I need to pick out so I can tell my macro when to stop looping. I have dimmed it as "c" in the code above. Following is the XML.
<search>
<total_items>360</total_items>
<page_size>100</page_size>
<page_count>4</page_count>
Somehow I need c = "4", which is the "page_count". Does anyone know how I can pick out the "4" from the xml on my page?

I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work.

The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.
