Hi,
I have a ASP.NET page, in which I have to compare two Dates. One comes from Database, and other one is selected from Calendar Control, assigned to textbox. When I code...
If CDate(txtDespDate.Text) < CDate(MasterDispDt) Then
LabelMsg.Text = "Invalid Date Selection"
Exit Sub
End If
This is the Error I am getting,
Error Message: Conversion from string "21-04-2009" to type 'Date' is not valid.

use DateTime.ParseExact to convert your date in "dd/mm/yyyy" fromat to "mm/dd/yyyy" format, since sql only recognises the latter format.
eg:
<br />
Dim invoicedate As DateTime = DateTime.ParseExact(Inv_Date.Text, "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentCulture)
Hope it helps...
When you fail to plan, you are planning to fail.

To convert a string to date, the date format should be MM/DD/YYYY OR MM/DD/YY.
The date "21-04-2009" is in the format dd-mm-yyyy.
This is the reason for the error.
Convert the string to correct format and your will get the result.

You need to understand what happens on the server and what happens on the client. OnClientClick is what you want to call. Return false to stop a postback.

You can also do like this:
YoubtnID.Attributes.Add("onclick","return btnGetDetails()");
Then put the code in Page_Load Event

????????????????

n is a letter, not a word.
What do you mean by client caching ? How does the client cache something you've not sent yet ?

sorry to write 'n' actually that means "and"
and i mean that is it possible that once we send all data from a table to a client system that using caching autocomplete extender will work inspite of using server database again and again..
so that autocomplete extender will work more quickly...
i m having near about 4000 records in a table..

You can achieve this using the css properties define these styles and inherit them in the autocompleteextender control
//This is for complete list
.CompletionListCssClass
{
background-repeat: repeat-x;
background-color: #FFFFFF;
z-index: 10000;
width: 245px !important;
max-height: 210px;
text-align: inherit;
text-indent: -1;
list-style: none;
overflow-y: scroll;
scrollbar-arrow-color: #B89020;
scrollbar-base-color: #8E6E1C;
scrollbar-face-color: #B6C5D4;
scrollbar-3dlight-color: #8E6E1C;
scrollbar-highlight-color: #EED47D;
scrollbar-shadow-color: #959595;
scrollbar-darkshadow-color: #00337E;
margin-left: 0px;
border-bottom: 1px solid #B5C6D4;
border-left: 1px solid #B5C6D4;
margin-top: 0px;
}
//This is for complete list with items
.CompletionListItemCssClass
{
background: none;
border-collapse: collapse;
color: #00337E;
white-space: nowrap;
text-align: inherit left;
}
//This is for highlighted item
.CompletionListHighlightedItemCssClass
{
background-repeat: repeat-x;
background-color: #EED47D;
color: #00337E;
border-top: 1px solid #FFF8E8;
border-left: 1px solid #FFF8E8;
border-bottom: 1px solid #00337E;
border-right: 1px solid #00337E;
}

Hi,
when i debug my site it is giving "unable to connect to the asp.net Development server" msg box.
what is this problem, how it will come. and what is the solution for this problem.
plz help me friends.How to solve this problme. if I reinstal the vs 2008 then the problem is solving..
but i need alternate solution for this.
Thanq,
|

Sometimes before you post, go to google and check how the other people solved the problem, you might find that there are a lot of people who had a problem and solution.
check this
Go to the Solution Explorer in Visual Studio, click on the web site application, hit 'F4' key to bring up the application's property window. In this property window, set 'Use Dynamic Port' to 'False', and you will be able to set the Port number to a number other than 1277.
See this MSDN document:
http://msdn.microsoft.com/en-us/library/ms178109(VS.80).aspx[^]
or
Step 1: Select the “Tools->External Tools” menu option in VS or Visual Web Developer. This will allow you to configure and add new menu items to your Tools menu.
Step 2: Click the “Add” button to add a new external tool menu item. Name it “WebServer on Port 8010” (or anything else you want).
Step 3: For the “Command” textbox setting enter this value: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\WebD ev.WebServer.EXE (note: this points to the web-server that VS usually automatically runs).
Step 4: For the “Arguments” textbox setting enter this value: /port:8010 /path:$(ProjectDir) (or any port you like)
Step 5: Select the “Use Output Window” checkbox (this will prevent the command-shell window from popping up.
Once you hit apply and ok you will now have a new menu item in your “Tools” menu called “WebServer on Port 8010”. You can now select any web project in your solution and then choose this menu option to launch a web-server that has a root site on port 8010 (or whatever other port you want) for the project.
You can then connect to this site in a browser by simply saying http://localhost:8010/. All root based references will work fine.
Step 6: The last step is to configure your web project to automatically reference this web-server when you run or debug a site instead of launching the built-in web-server itself. To-do this, select your web-project in the solution explorer, right click and select “property pages”. Select the “start options” setting on the left, and under server change the radio button value from the default (which is use built-in webserver) to instead be “Use custom server”. Then set the Base URL value to be: http://localhost:8010/
Obviously I don't know if this is the problem you had but definitely it is something similar, essentially the problem should be that the same port used by your Development Server is not available because it is already used by another web server.

Hi, thanks for looking
Im using ntier datasets in vs2008: Windows client - webservice - DAL with dataset
I have a save method in webservice as well as in DAL, they take a dataset as a parameter byref
The problem is with new rows, the primary key is an autoincrement column
When i send the changes to the webservice, i cant merge the result with my client dataset because ill get duplicated rows for the added rows
I know i could do something like this once i get a response from the save method in the windows client:
Find all added rows in client dataset for each datatable, delete them, merge the client dataset with the dataset returned from the webservice and call acceptchanges. Tha works fine, the thing is that ill be using this in many forms and also the dataset contains like 6 tables that are being updated in the webservice, there must be any other way to do it.
If i use the individual tableadapters and set the acceptchangesduringupdate=false, IT WORKS, since the dataset will keep the original autogenerated id and the real autogenerated id by the DB
I wouldnt like to use individual tableadapter, since i am updating like 6 tables at once with the tableadaptermanager, and saving them with individual tableadapter will be a real pain
I already tryed sing something like this (but doesnt work):
Dim ta As New dsXTableAdapters.TableAdapterManager
ta.XTableAdapter = New dsXTableAdapters.XTableAdapter
ta.XTableAdapter.Adapter.AcceptChangesDuringUpdate = False
Also tryed capturing the rowupdated event of the adapter (And didnt work either):
Private Sub _adapter_RowUpdated(ByVal sender As Object, ByVal e As System.Data.SqlClient.SqlRowUpdatedEventArgs) Handles _adapter.RowUpdated
If e.StatementType = StatementType.Insert Then
e.Status = UpdateStatus.SkipCurrentRow
End If
End Sub
Any suggestions??

Do you know anything about ASP.NET ? What is it ? What does it do ? What are it's limitations ? This is a question that tells me you don't know much and need a basic book. Perhaps I will change my mind if you ask something more specific, but that's what I think right now.

Hi
I am creating a social community & for that i need help in two things:
1)I have database containing questions. I want these question to appear dynamically on pop-up window(like MSN Messenger pop-up window appears "ABC is online now"). And then save user selectable answer in database.
2)chatting with friends on community as on happens facebook and orkut.
Thanx in advance.
Waiting for sample code OR video illustrating answers of post.

chatting requires AJAX. Questions and answers require a database.
