Start and end date ???

Thread began 10/11/2010 11:44 am by nmabey414064 | Last modified 10/14/2010 3:43 pm by Dani Chankhour | 1387 views | 8 replies |


Start and end date ???

The graph is displayed but there are no bars displayed. The tootlip only says "undefined".
I am connecting to a MSAccess database. The code looks like this:

Set WADWCStats_cmd = Server.CreateObject ("ADODB.Command")
WADWCStats_cmd.ActiveConnection = MM_diagramm9_STRING
WADWCStats_cmd.CommandText = "SELECT Stats_Date AS XLABEL, Stats_Date AS YVALUE FROM Stats WHERE Stats_Date >= #07-July-2010# AND Stats_Date <= #14-July-2010#"
WADWCStats_cmd.Prepared = true

Is there any SQL Date Problem using VB and MSAccess?

Can the dates also be set dynamic? eg. the customer choose dates with a datepicker or they are forwarded through input fields?

Thanks a lot, please be patient I am new to this all!

The chart is working now with set start and end date.

Can these dates also passed dynamic? e.g. a user picks dates with datepicker and than they are passed to the chart?

Thanks a lot for all the help

yes. you can pass the dates dynamically using the date picker, you will just need to make sure it is passing the right date format.

gone dranock

Thanks you for your reply.

But how?

My Query with manually picked dates (in the wizzard) reads:
"SELECT Date AS XLABEL, Minutes AS YVALUE FROM Stats WHERE ID= ? AND Date >= #07-09-2010# AND Date <= #07-12-2010#"

Now I would like to replace #07-09-2010# and #07-12-2010# with the values(variable) in the url (mysite2.asp?ID=4&StartDate=10-14-2010&EndDate=10-23-2010)
for StartDate and EndDate. These variable are passed into the url from a form (on prevoius page (.../mysite1.asp)).

I though of something like this:

Dim WADWC__ParamStartDate
WADWC__ParamStartDate = Request.QueryString("StartDate")
Dim WADWC__ParamEndDate
WADWC__ParamEndDate = Request.QueryString("EndDate")

SELECT Date AS XLABEL, Minutes AS YVALUE FROM Stats WHERE ID = ? AND Date >= @WADWC__ParamStartDate AND Date <= @WADWC__ParamEndDate "

But It doesn't work like this. Thanks for all your help!

sorry just seen that the url doesn't show right...
url reads (.../mysite2.asp?ID=4&StartDate=10-14-2010&EndDate=10-23-2010)

I have read that the when I want to create a string, I must enclose the date in hashes so my next attempt looked like this:

Setting the variable like the wizzard is doing for the for other variables
(e.g. the ID when I filter by URL):
Dim WADWC__ParamStartDate
WADWC__ParamStartDate = "-1"
If (Request.QueryString("StartDate") <> "") Then
WADWC__ParamStartDate = Request.QueryString("StartDate")
End If
and then the query:
Set WADWC_cmd = Server.CreateObject ("ADODB.Command")
WADWC_cmd.ActiveConnection = MM_Calendar6_STRING
WADWC_cmd.CommandText = "SELECT Date AS XLABEL, Minutes AS YVALUE FROM Stats WHERE Site_ID = ? AND Date = #" & WADWC__ParamStartDate & "#"
WADWC_cmd.Prepared = true
WADWC_cmd.Parameters.Append WADWC_cmd.CreateParameter("param1", 5, 1, -1, WADWC__ParamSite_ID)

Sadly this doesn't work? WHy? Where am I doing the mistake?

Thanks for the help

The chart works when I wether send an ID or a date but not both...

The URL reads:

and I get the error:

for some reason I have the feeling the graph should receive both ID and StartDate and not only the ID as the error message suggests.

The object that is created by the wizzard is:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase=",0,28,0" width="940" height="300">
<param name="movie" value="DynamicWebCharts/open-flash-chart.swf?data=DynamicWebCharts/Data/page2_dataparser1.asp?<%=Request.QueryString()%>" />
<param name="quality" value="high" />
<embed src="DynamicWebCharts/open-flash-chart.swf?data=DynamicWebCharts/Data/page2_dataparser1.asp?<%=Request.QueryString()%>" quality="high" pluginspage="" type="application/x-shockwave-flash" width="940" height="300"></embed>

and I think here is the mistake.

When I replace <%=Request.Querystring()%>
the chart receives the ID and displays.

When I replace <%=Request.Querystring()%>
the chart receives the StartDate and displays.

But how do I pass both variables to the chart?
Do I have to change something in the <object> bid? What?

Thanks a lot and sorry that I put more and more questions up here but I thought it might be better to understand my problem.

the mistake was in the <object> bid.

I tried to connect the different variables with an "&" sign. But when passing variables from html to flash via Query String I need to use "%26" istead of the "&". How should you know that :).

I am sorry for posting and posting my thoughts here, but maybe it will also help somebody else.

I'm glad you got it to work.

sorry i was not able to help you out with this issue since I'm not that familiar with ASP.

Again, thanks for posting your solution.
