Has anyone had any trouble with concatenation with the new 2.0 framework. Here is the scenerio. We are migrating our site from 1.1 to 2.0 and I am working out some bugs and found this to really funny.
UnitStr += sdr("UnitID")
UnitStr is defined a string and sdr("UnitID") is pulled from the database as an integer. In the 1.1 framework(VS2003) it allows it to conncatenate but the 2.0(VS2005) it gives me a "input string is invalid", "Conversion from string "" to type 'Double' is not valid.". The funny thing it shows as an integer in the table and when you watch the variable.
Any one have any ideas?
Keep putting the pieces of the puzze together. Thats a programmer!@

try using &= instead of +=

I'd say not to use EITHER....look for String concatenation memory c# in google.
The suggestion is to use the StringBuilder class....

Request.InputStream.

Here is my code
Stream receiveStream = Request.InputStream;
PdfConverter pdfConverter = new PdfConverter();
pdfConverter.PdfDocumentOptions.PdfPageSize = PdfPageSize.A4;
pdfConverter.PdfDocumentOptions.PdfPageOrientation = PDFPageOrientation.Portrait;
pdfConverter.PdfDocumentOptions.PdfCompressionLevel = PdfCompressionLevel.Normal;
pdfConverter.PdfDocumentOptions.UseMetafileFormat = true;
pdfConverter.PdfDocumentOptions.ShowFooter = false;
pdfConverter.PdfDocumentOptions.ShowHeader = false;
pdfConverter.LicenseFilePath = Server.MapPath(@"~/Bin");
byte[] downloadBytes = pdfConverter.GetPdfBytesFromHtmlStream(receiveStream, Encoding.UTF8);
System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Type", "binary/octet-stream");
response.AddHeader("Content-Disposition", "attachment; filename=" + "Rendered.pdf" + "; size=" + downloadBytes.Length.ToString());
response.Flush();
response.BinaryWrite(downloadBytes);
response.Flush();
response.End();
I am getting this error
Message = "Could not get the HTML file from the string. A generic error occurred in GDI+.."
if I use the uri to create the request and get the stream and pass it to the pdfconverter
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
byte[] downloadBytes = pdfConverter.GetPdfBytesFromHtmlStream(receiveStream, Encoding.UTF8);
It works fine but not when I pass the HttpRequest Page.Request inputstream.Could anyone please correct me and help resolve this.
Thanks

I try to loop through the controls in the page and to identify certain controls, but I can't locate them.
Here is my code:
Protected Sub submitBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitBtn.Click
Dim errMsg As String = ""
For Each ctrl As Control In Me.Controls
If TypeOf ctrl Is TextBox Then
errMsg &= "Found it!"
Else
errMsg &= "Nothing Found!"
End If
msgText.Text = errMsg
Next
End Sub
When I trace the ctrl as String output I get ASP.masterpage_master
|
|
|
|
|
Try by the Page.control

Didn't work either, tried that before! (using Masterpage!!!!)
|
|
|
|

Found the solution:
Protected Sub submitBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitBtn.Click
Dim errMsg As String = ""
Dim ctHolder As ContentPlaceHolder
ctHolder = CType(Master.FindControl("ContentPlaceHolder1"), ContentPlaceHolder)
For Each ctrl As Control In ctHolder.Controls
If TypeOf ctrl Is TextBox Then
errMsg &= "Found it!" & ctrl.ID.ToString() & "<br />"
End If
Next
msgText.Text = errMsg
End Sub
Thanks so for the suggestion!

I am trying to desn dynamic pages in visual studio. When I go to style and set a background image for the web pages I am designing, my images are not showing up. Whether it is a table cell, layer, or a page background property, its not showing up through the browser only during design mode. anybody know why this is?? I am puzzled. I know it can be done becuase MS has starter templates that look nice but I am trying to desgn my own template.
Any suggestions?

I'm having a problem. I have put 2 images on the page and was able to see them but but when i run the project I'm unable to see/view my images.

I would guess you forgot to include the images into your project. It is common to in the project create an images directory. Then right click the images dir and add existing items. Once the images are included in your project I would guess they will show up.
hope that helps.

Hello
VS 2005
I am using the code below to get and save the connection string in the web.config file. However on the webConfig.Save() line it throws an error:
An error occurred loading a configuration file: Access to the path 'c:\inetpub\wwwroot\Incidents_WS\oa48wsfg.tmp' is denied. (c:\inetpub\wwwroot\Incidents_WS\web.config)
I am not sure what this file is "oa48wsfg.tmp" and why I have access denied.
<br />
Dim cnnString As String<br />
'Get the current connection string<br />
cnnString = WebConfigurationManager.ConnectionStrings("serviceMasterConnectionString").ConnectionString()<br />
cnn.ConnectionString = cnnString<br />
<br />
'Save a new connection string<br />
Dim WebConfig As Configuration<br />
WebConfig = WebConfigurationManager.OpenWebConfiguration("~")<br />
WebConfig.ConnectionStrings.ConnectionStrings("serviceMasterConnectionString").ConnectionString = "data source=steve01\ssd01; database=serviceMaster; user id=sa; pwd=a123"<br />
WebConfig.Save()'Error on this line.<br />
I have gone into the IIS and right click web.config and given read and write permissions. but still get the same error message.
Can anyone please help me with this problem.
Many thanks,
Steve
