It's been requested of me to create an application to allow uploading a text file.
I've created the app using the FileUpload control and then was told that I need to check that there is specific data, in specific columns, to verify that the correct text file was uploaded.
i.e.; date in column 5, a number in column 6, an email address in column 15, etc...
- I used a StreamReader with the saved path of the file as the file to a string variable called sCurrentRow.
- Now, because my file does not have column headings, I had to use 'LastName_tx = Strip(Trim(Mid(sCurrentRow, 3, 25)))'
- I'm using VS 2013
I found a site which indicates they can export a GridView as Word, Excel, PDF, and CSV. The PDF uses an external library (iTEXT), and I have not tested that. [URL] ....
The CSV worked for me as specified. But I am having trouble with the Word and Excel portions. The code for the Word sub is
Code: Protected Sub btnExportToWord_Click(sender As Object, e As EventArgs) Handles btnExportToWord.Click Dim s As String Response.Clear() Response.Buffer = True Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.doc")
[Code] ....
The marked line above triggers an error which states
Code: Control 'MainContent_GridView1' of type 'GridView' must be placed inside a form tag with runat=server.
Note, that the code never gets the Response.Output.Write line, but the file is downloaded, and looks correct.
My real need is to download the excel file, but it has the some behaviour. It fails at a similar RenderControl statement, but does download the file, although Excel indicates it is in a non-standard format (but looks fine when opened. I can upload that code too, but the Word one above is simpler.
I would like to use HTML input file type in my aspx page to allow user to browse for a excel file and then read the content of the excel sheet programmatically.If I want to read the excel sheet I need the full path of the file to connect to the excel sheet using asp.net.I do not understand how can I get the full path of the file.I know I can get the filename using postedFile.FileName property.But I need the full path of the file.

I want to keep the uploaded file name to make it possible to users to download the file under the same name. But how can I implement it? The one option I see is to store each file to folder with unique name (GUID, for example).
I have a web form that uploads files by <asp:FileUpload> control. It uploads files to any folder on the disk (path to uploads can change in web.config, for example "c:UploadedFiles"). After file has been uploaded I need to show a link on the WebPage to download this file.
How it's possible create a link to this file (or what is another solution) on the web page if my website is in completely different place!?
I need to create a custom web control which will be a part of a class library. This custom web control implements the upload functionality. I have implemented this with a web user control where I have a fixed path to a page in the web project where the upload of files take place and it works just fine.
The created control in this class library is used in the web project. How do I post the uploaded file to a page, say SomeClass.cs, in the class library.
Actually i am trying to storing the uploaded file into database but when i run this codes:
[Code]....
I got this error: " Incorrect syntax near the keyword 'File'.Incorrect syntax near the keyword 'File'. " can anybody tell me why this error came out?I tried toi change my connection string in web config,but it still showing the same error each time i run it in my local.
I am building a user control for other programmers that I work with. It will be used to interface with our Authorize.Net accout. Is there a way in code to verify that the connection is SSL? If it isn't I'm going to disable the code to keep any of our programmers from accidentally trying to use the user control on a page that isn't SSL.

I want to upload csv file and import the data into sql. but I cant do the import thing. The file is uploaded but it cannot be imported into sql. This is my code. Hope that someone can tell me what is the problem.
I wanted to customize/Restrict the File Uploader control as follows:
1. To restrict Users to not to upload some type of file like.exe
2. To restrict the user to a specific size limit.
I also wanted to be able to display appropriate messages to the user if the abover restrictions are violated.
Can I use the validations control to achieve the above goals. As I am already using these controls to display appropriate messages to the user in case of wrong/invalid data.
I have made a document uploading page, In which use can upload their document. I am saving three fields in the database,
Document Name [NVarchar] File [Image] DocumentType [NVarchar]
Now, I am able to add records in the database, successfully. Now I want to show it in the gridview, like DocumentName, DocumentType and a link to download the file.
I have tried by retrieving the records and assigning them to the gridview but I am getting only two columns.
I have an ASP.NET FileUpload control, which allows only image type. I used RegularExpressionValidator like below.
<asp:FileUpload ID="fuPhoto" runat="server" TabIndex="40" /> <asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ControlToValidate="fuPhoto" Display="Dynamic" ErrorMessage="* You can only upload .jpg, .gif or .png image types." ValidationExpression="^.*.(jpg|JPG|jpeg|JPEG|gif|GIF|png|PNG)$">* You can only upload .jpg, .gif or .png image types.</asp:RegularExpressionValidator>
This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.
I have a page set up that allows users to upload files to the server, and then uses a database entry to attach the file to a project. When the project opens, I load a gridview with the list of files, and create a hyperlink to the file like this:
Code: Protected Sub gvFiles_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvFiles.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then ' Dim oLinkButton As LinkButton = e.Row.FindControl("lbDescription") Dim oSQL As New clsSQL
[Code] .....
When I try to click on the link, and select Open file, I get the following error:
I notice the type is right here, but on the open screen it isn't:
It says Type compressed Zip Folder for some reason. What I am doing incorrectly?
I'm testing a site that serves up some binary (i.e. non-HTML) content. Some links directly deliver custom images, other links custom PDF's.
I'm building test cases in WatiN and NUnit. Wondering if there's a way, using WatiN to get it load a page and then get the byte[] contents of that page.
Currently, I'm just launching a WebClient to grab the content, rather than through WatiN but that's more untested code in my test suite.
I want to execute following lines only if user has selected "Other" from dropdownlist. Could you please tell me how to do this?
<%: Html.TextBoxFor(model => model.Category) %> <% Html.RenderPartial("ImagePicker", new ImagePickerViewModel() %>
Moreover, I want to make sure that when user clicks Save button(available on view), he has inserted the valid image name and selected the Image otherwise display error.
