Databases :: User Validation In Xlsx File Error "Data Type Mismatch In Criteria Expression".?
Dec 9, 2010
I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names. So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

I am importing data from an Excel worksheet. The columns are labelled aa, ab, ac .... in row1 and the rows are labelled with integers in col aa. Although I can import the entire worksheet (so long as it isn't too big), when I add a WHERE clause to import only a single row I get a type mismatch which I have not been able to isolate. How can I make progress.

In the access database the date field is of datetime type. The dates are in european DD.MM.YYYY format which i transform using datetime variable and convert function. The sql query runs fine in access database but when i run it thru my oledb connection in my asp.net page it gives me errors. How should i modify my query, or make adjustments to my code, to not get this error? Do i need to send the datetime as a parameter? And how do i do that? Here is the code for the search event:

there is an upgrade to my infimacs server and my web application encounter this error after the infimacs is upgraded.
Below is the information on the server before/after the upgrade.
Before After
--------- -----------
Solaris 8 Solaris 10
IDS 9.40 IDS 11.50
The web server where the web application hosted is running IBM Informix Connect 2.81. There is no such error before the upgrade is done.
As a developer, i have IBM Informix Client-SDK 2.90 installed on my local pc and debug the page where the read is needed from infimacs but no such error found.
The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.
I have gone through many articles and it suggest me to set the environement variable in the server : DB_LOCALE=en_us.819.
I haven't try this solution but i think that this might not be the best solution.
Is it possible to to to have this setting in the web application ?Does anyone has idea on this?Is it true that there is no other solution than setting the environemetn variable DB_LOCALE?
Below is my connection string
"Host=192.168.100.xx;Server=infimac;Service=1527;Protocol=onsoctcp;Timeout=120;Database=abc;uid=userid;pwd=password"

I am using C# windows based GUI and MS-Access as my database. Unfortunately, I cannot insert a record with a numeric value, this means that one of my field is a number data type. Below is my code;
Code:
strItemCode = lvProducts.Items[i].SubItems[0].Text.Trim();
iQty = int.Parse(lvProducts.Items[i].SubItems[2].Text);
cmAdjustedItems.CommandText = "INSERT INTO tblAdjustedItems VALUES(@itemcode, @adjustmentid, @qty)";
cmAdjustedItems.Parameters.AddWithValue("@itemcode", strItemCode);
cmAdjustedItems.Parameters.AddWithValue("@adjustmentid", strAdjustmentID);
cmAdjustedItems.Parameters.AddWithValue("@qty", iQty);
cmAdjustedItems.ExecuteNonQuery();
All the variables in my code were properly declared.

I get the following error message:
Could not find file 'C:CHURCHROOF - CRIME live 150110.xlsx'.
When running the following code:
if (FileUpLoad1.HasFile)
{
string serverpath = "\\server1\Temp\ ";
//top.window.close();
string filepath = FileUpLoad1.PostedFile.FileName;
string filename = FileUpLoad1.FileName;
string destination = serverpath + filename;
//File.Delete(destination);
string[] existingFilesArray = System.IO.Directory.GetFiles(serverpath, "*.xlsx");
foreach (string existingFile in existingFilesArray)
{
System.IO.File.Delete(existingFile);
}
File.Copy(filepath, destination);
}
The code looks for a file and uploads the file to another location.
it fails at the last section
It works for me on my machine. but not the users
File.Copy(filepath, destination);
NO matter were the users put the file it fails.

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should. There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.

I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.

Using the Interop for Excel 2003 I had a nice little link that saved or opened the repeater content as .xls. Now we are using Excel 2007 and I get file format error messages. When I click the OK button on the error pop-up Excel closes. Does anyone out there know how to convert my code to handle the .xlsx format? I've been reading up on Interop for 2007 but none of the examples seem to work for this particular simple task. Here is my code from the "Export to Excel" button click:
Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
' Send HTTP headers that specify Excel filename, MIME type, and character set
Dim sTemp As String = "attachment;filename=CoverageCase" & Session("OpenCase").casekey.ToString & ".xlsx"
Response.AddHeader("content-disposition", sTemp)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
' Create objects used to render the controls
Dim strw As New System.IO.StringWriter........
I found a thread from a couple of years ago dealing with this but there was no solution [URL]. There were a couple of tortureous work arounds but neither work for me.
