Hello,
VS 2005
I have a combo box that is bounded to a combo box.
The combo box will load orders into it.
I want to be able to insert "All" into the first element:
Me.cboOrdersCompleted.Items.Insert(0, "All")
However, as the combo box is bound to a binding source it won't all me to insert this word.
The method I have used to fill the combo box is as follows:
Me.cboOrdersCompleted.DataSource = Me.bsOrders<br />
Me.cboOrdersCompleted.DisplayMember = "OrderID"<br />
Me.cboOrdersCompleted.ValueMember = "OrderID"
My problem is when I insert the word it does this without any errors, but doesn't show. If I insert the word after the combo has been filled, then it will give me the error that the "Items cannot be modified once the combo is bound to a datasource"
Is there anything I can do to add this "All" into the combo box?
Many thanks for any suggestions,
Steve

Manage the bindng yourself. I have never used MS's binding due to its limitations.

Hi,
I am using an html input box to populate a variable, which is in turn used as a date in a query that interrogates my database.
The problem I am having is that the date needs to be in the format "yyyy/mm/dd hh:mm:ss" for the sql query to work and I cannot find any way of converting the date into this format (I can only seem to convert it to dd/mm/yyyy or mm/dd/yyyy).
can anyone help??
thanks

|

Why do you have to have the hours/minutes/seconds for the query to work? Is it used later on?

You can specify exact formatting for a datetime by using
Dim formattedDate as string = myDate.ToString("yyyy/MM/dd hh:mm:ss")
|
|
|
|

In reply to both the posts so far:
1) I do not neeed the time - it's just the date in the correct format.
2) using the .ToString has come up with the following error:
Microsoft VBScript compilation error '800a0401'
Expected end of statement
/Home/Act_report_packs_in.asp, line 19
Dim formattedDate as string = DateTo.ToString("yyyy/MM/dd hh:mm:ss")
------------------^
Is this .net specific??
I have managed to work around it by using the left(), mid() and Right() functions on the string and then re-arranging them, but it would still be nice to have a 'neater' way of doing it??!
thanks

Normal rules apply: for values that can change, particularly ones supplied by the user, you should use a parameterized query. You should only break this rule if your database provider doesn't support parameterized queries.
In classic ADO, use the Command object's Parameters collection. See your provider's documentation for how to indicate a parameter (for SQL Server, you can use named parameters by using an @ symbol followed by a name). Some providers only support positional parameters.
For a date/time value, you probably want the adDBTimeStamp data type for your parameter. You'll have to convert the value in your input box into a VBScript Date value. For that you probably need the DateSerial function.

I am creating an advanced search page.in that I have 11 fields.i wrote a stored procedure which has all 11 parameters.
If I don’t enter any value for the parameters I am not getting the result and it goes to exception handling.
Now what I want is even I enter one value this must be excute………….i think some validations must applied to Stored procedure's where clause.but I don’t know how …………….can anyone help me regarding this
would be thankful if you send the code for this
Thanks

These type of queries can get messy quick. Normally you need one table that will always be returned no matter what is being searched on. So that is the first table in the statement. All other tables that are optional need to be left joins to that first table other wise you won't get any rows returned. Then in your where clause you have to do some stuff like:
where (@param1 = null || table2.column = @param1)
It can be a real mess. The only other option is to dynamically create your query in your stored procedure and then call Exec on that sql statement.
Hope that helps.

I want to enter the date in my mysql table so that when I read from the database, I can read only the entries entered on that day or the latest. How do I do this. which datatype should I enter.
I tried with unix_timestamp() but it saves in seconds, so wont it result in lots of arithmetic calculation?

Hi,
I am having a stored procedure whose output directly binds to the datagrid. The procedure is having a select query as follows:
SELECT P. Project_id as ID, P.Project_Name as Name , P.Project_version as Version , P.Project_Description as Description ,Convert (VarChar(15), P.projected_start_date,106) as ProjectedStartDate , Convert(VarChar(15),P.projected_end_date,106) as ProjectedEndDate,P.actual_start_date as ActualStartDate, P.actual_completion_date as ActualCompletionDate
FROM tblProjects P
INNER JOIN tblProjectType PT ON P.Project_Type_Id = PT.Project_Type_Id
/*ORDER BY P. project_type_id*/
WHERE P.is_active=1
Here the ActualStartDate and ActualCompletionDate can have some mininum date value like '11/09/1753' or the actual dates entered by the user. If the ActualStartDate is '11/09/1753' then i want the to get it as null or empty string and then bind it to the datagrid. so in the datagrid under the ActualStartDate where '11/09/1753' is present, it will actually display null or empty.
Thanks,
Riz

Compare ActualStartDate with DateTime.MinValue. if its same treat as null or empty...
|
|
|
|
|
ya...i knw that i have to compare the ActualStartDate with DateTime.MinValue But how exactly to do it in the stored procedure?
Let me knw if u have got any solution.
Thanks,
riz

I am in the same boat on a project. It is said to be "bad design" to allow nulls and you should avoid doing so at all cost. Visual Basic shows the actual dates in the database so I have many fields with the date 12/31/9999 11:59:59 PM which is the max date. It seems that if something is such bad practice they would accommodate it better than they do. I will be watching this topic for answers, also if I find an answer I will be sure to post it here.

Hello everybody!
I have a small question.
I don't know how to insert a null DateTime value into database.
In my form, I have a textbox-based field named OrderDate. If the user doesn't set value of this textbox, when inserting, I consider the value 1/1/1900 is added to database unexpectedly. I don't like this, I like empty. How should I do to get empty in Database.
Thanks in advance !
It seem to be a solution or an answer.

There is a sqlDataTime object that has a null property. I would suggest passing that into the parameter.
Hope that helps.

hi i have installed SQL7 on my Machine. but when i try to register a Server it gives me this error.
"The Application has Failed to start because VNSAPI32 was not Found.Reinstalling the Application may Fix this Problem"
i try to goggle this Problem , i only found one Answer but its in Arabic , cant read. So i tried to reinstall it again it gives me the same Error
Please Help

Why are you using SQL Server 7.0??  It's older than dirt itself!
|
|
|
|
|
VNSAPI32 is the Banyan Vines network protocol library. Try using the Server Network Utility or Client Network Utility to disable this very rare protocol and try again.
I think that's how you do it, anyway - it's been years since I've used SQL Server 7.0 (I'm struggling to recall if I've ever used SQL Server 7.0).

Hi all,
I need a way out of this sql server querry. I have a database wich stores username with space in-between. the porblem am having is that when I run a search query using like operator it returns no value. e.g
in my table I have a username stored their called "acod man" but i want to search by entering acod since i am using like operator I want it to locate "acod man" for me but it returns nothing
select username from tbl_names
where username like'%acod%'
I will appreciate your responses.
thanks in advance.
|
|
|
|
|
It should work perfectly. I dont see any reason for this query not working.
I have tried a similar query as:
select c1, c5 from t1 where c5 like 'R%'
and this returns all the records for which c5 columns has values starting with 'R'.
Juz try it again. Otherwise provide table records and structure...
Letz see whats the probs??

Tell me what is the type of column for which you are doing pattern-matching??
If the datatype of the column is nchar then it will return 0 records.
Bcoz then its Unicode pattern - matching...
