• Visual Studio Reporting Services, Reportviewer control & browser compatibility.

  We are planing on using the reportviewer control that comes with the standard edition of visual studio 2005. I have noticed that the rendering is not the same in Firefox and I.E. Event the tool bar is wrong. Is this control supposed to work non MS-Browsers Can I fix it by editing some css files, or do I need to derive my own control from the supplied control, to tweack the html it produces. It would be nice if it worked for most browser out of the box. Fred. Watch the way you word your question. Very compatible, you just don't get any features! http://msdn2.microsoft.com/en-us/library/ms156511(SQL.90).aspx ...Show All

• SQL Server yyyymmdd text data into a datetime field in SQL Server?

  Hello, I have an Excel spreadsheet that contains 100,000 + rows of data. Two of the columns in the spreadsheet are date fields that are sent over in the yyyymmdd format (no separators such as "-" or "/"). I tried converting these fields into dates using the Data Conversion task in SSIS. This doesn't work as it appears that SSIS cannot map a string in the format of yyyymmdd to a valid date. In lieu of this, I have added a Script Component to my transformation which can take the string and convert it to a date value using some Substring() calls on the source yyyymmdd string. A few questions for the group ... 1. Is ...Show All

• .NET Development POST fails on larger messages/slower connection

  I have a webservice receiving encoded strings of a size usually between 1k and 20MB which will be sent by a special application. When the application is started, it sends about 1000 of these strings to to the server, checking response and sending again, if necessary. Im using Framework 1.1, no additional stuff (like WSE) installed. Only known users are allowed to access the webservice. The server is configured to handle these bigger requests by adding maxRequestLength="40960" and executionTimeout="3600" to its web.config httpRuntime-Node. To reduce the number of requests sent by the client, i set the PreAuthenticate-prope ...Show All

• .NET Development Question following "Why Soap not RPC"

  thanks for all your replies. I heard that RPC can transfer the binary stream but SOAP can transfer the text stream. But the data during transferring are both 0 or 1 bits, what part will differentiate the two kinds of streams How the SOAP protocol deal with the stream Hi Xudeutsh. First, RPC is a style rather than an actual protocol. Examples of protocols which implements RPC style can be DCOM or RMI. DCOM and RMI are binary protocols, that is to say that their payloads are expressed in binary terms. SOAP and XML in general, on the other hand, are expressed in text. The moment in whi ...Show All

• Visual Studio Team System URL Encode option for QueryParameter does not work

  In a webtest's QueryString Parameter, there is an option to specify whether you want to URL encode the value or not. However, this option seems to be ignored by the webtest engine. Let's say that I want to send a > symbol as it is - not as %3E but as >. (yes, I know RFC 1738, but this is a TEST for my app). So I specify > as value in the UI and say "False" for URL Encoding. However, when the webtest engine sends the request, it ignores that user's specification and still sends the encoded version. In IE, it works - I can specify this in the browser's address and IE will actually send out that character. Is th ...Show All

• SQL Server Oddball SQL calculation query - any Gurus up to this??

  OK, so I have a situation where the Client gets money from activites based on mileage. The further from 'home', the greater the mileage rate is. The distance per stopover is measured from wither home, or the last stopover, making it a continuous interval. Dependinig on the load size, the rates will increase or decrease as well. Assume the following are skeleton table structures. Table structures assume that appropriate keys are in place as 'Keyfields': Table1Fields: <Table one holds the actual user-entered data per Size> Key Keyfield(s), <keys to Table2's Keyfields> Size Varchar, DistanceFrom Number, (all ...Show All

• Visual FoxPro checking RTF control for EMPTY ()

  I have trouble checking programmatically that RTF.textRTF is empty. If it is visually empty to the viewer the function EMPTY (RTF.textRTF) returns .F. If I use an assignment m.memVar = RTF.textRTF I can print it out as a set of strings (about 3) of formatting characters. It is after the control was filled with some text and subsequently that text was deleted (manually) in the control window. How can a test be done to verify that the control is empty Thanks. The presence of additional formatting characters also creates another problem. If I want to encrypt the content of RTF.textRTF those characters get in the encryption and when ...Show All

Does anyone have any good information regarding this Using SQL express database is really simple, if you are already used SQL Server. There is only difference in connection string where instead of Setting Data Initial Catalog, you should set AttachDbFilename with file path to your database mdf file.
