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 made a form in ASP.NET with VB background code.my problem is I want to make that the file which is been uploaded to by the form to change to "Resemey.doc" instead for example "012 MaraCSD.doc"did a bit of research and found out I need to add some code to my vb code.but couldn't find what, and where to put it.
this is my code:
'Add the namespace for the email-related classes Imports System.Net.Mail Partial Class SendAttachment
I need a snippet to check file for validity (I'm allowing users to upload xml files). So I need to check whether uploaded file is XML. The best I can think of is just check if extension is ".xml". What if its replaced?
I'm trying to get a specific error message posted when a user tries to upload a file that exceeds the maxrequestlength of 10MB for my asp:fileupload object. However, adding the onError attribute to my fileupload object, the user does not get the error I want displayed; the page just crashes. Setting customerrors mode to on and setting up a redirect page doesn't work either; the page still crashes. How am I supposed to get the page to display a specific error without crashing?
I am developing an application that will do 2 things:
- connect to a webservice
- Upload/download files through WebDAV.
Seems to work fine, but I am having an issue with debugging. Since WebDAV is installed on the server, i have to publish the webservices there aswell, as the webservice is going to access the file locally (serverside) after upload to the server. This makes it impossible for me to debug the webservices. When i switch to the local services for debug, they cannot reach the file that was uploaded to a remote location (the server). Is it possible to install a local WebDAV server, even if i do not have IIS set up? Just for testing purposes?
I am writing a code that downloads alot of information from different servers. Puts the information in an excel spreadsheet, saves the sheet, and uploads it to an FTP page for each server. The code is running into an OutOfMemoryException. Is there a way to clear the memory after each servers file is uploaded to the FTP?Or is there another way to fix the problem with out adding memory to the server the code is running on?
I have recently programmed a site that enables a user to upload and download files to and from an FTP site.
I now wish to take it further by having an email sent out to a specific email account (Outlook 2010) confirming that a file has been uploaded or downloaded along with the file name.[code]...
Having no real experience with updater-style applications, basically I want a secondary EXE to be bundled with my application which will update the program file. Its a one file application - so its a simple process. Its just for the PC's inside the business.Currently, I think it will be easiest to get the updater to check a text file uploaded onto our server, and determine whether the running version number is above or below that. The new application will then be downloaded from a simple http link.
-I have an interface designed, so that will be attached to my request.
-Is it possible for the updater to update itself? How could I request that?
-Is there any way I can ask that the link which the updated file will be downloaded from is definitely hidden from the user?
-Will the developer incorporate error handling for if the program is running when the updater runs? How do I ask for that?
Is there a better way for the updating process to run? What other things should I ask the developer to include?

What I'm trying to do is get the bytes already uploaded. I cannot seem to do this.Another problem: When uploading, the form will not move or change Label1.text. When pbUpload.value == 100, THEN it changes to a different number than label3.text.
Has anyone found a way to view it numerically?Im sure that for a multithreaded program that a seperate user stack is maintained for each thread?Inevtably. there will be the dunderhead who asks what I am doing. Im in the last stages of developing a multithreaded filescanning program. The program uses a fairly tight loop.
I'm working on a project that requires that I programmatically examine the ServiceAccount of all services installed on a machine (regardless of status) to determine Logon Type which will be used as an indicator of which passwords need to be changed on a machine for maintaining security.
If possible I would like to keep the entire project in VB.Net and Ive been looking through the API to find namespaces that contain classes to allow me to do this. Ive come across System.ServiceProcess which does allow me to get quite a bit of information about services installed, but I cant seem to find a way to get the Logon Type (I would guess that it would be returned as a System.ServiceProcess.ServiceAccount object).Ive also tried System.Management using ManagementObjectSearcher and ManagementObject, but Im not sure if theres a way to get that information with a WQL statement (I know next to nothing about WQL, unfortunately).
I am using ExecuteReader commands to read records in large external databases. Part of my program logic requires that a condition of the database be examined without reading another record - for instance, I want to know if the database has reached the end without reading an additional record.
I need to get data from a web application. I dont have access to database or the source of the app(.net).The web app works like this -- enter values in fields, click submit button, and the data associated with these fields are returned in a modal popup. I need to do the same programatically, without actually opening the browser.I need to know the name of the fields that need to be posted, and the URL. And then store the response.
I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
I have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?
I have a textbox on a form that is set to allow dragdrop operations from txt files.Basically you drag a .txt file onto the txtbox, the content of the text file is displayed in the textbox.All is working fine, however after the textfile is displayed in the textbox, the text box text is for some reason is highlighted.I don't want the text to be highlighted (or selected) after it's being displayed on the textbox.Second issue, after I close the file that I dragged, for some reason even if I didn't make any changes to the file, it is acting as if the file has changed.In another words, if I open a text file using my MenuItem Open item, and if I do not change the file, If I close the file it's fine it closes.However, if I close a file that I draged into the text box and then close the file without changing anything in it, the stringcompare function is telling me that the file has changed... I can't understand why.
I have a sample app here I could use a hand with Basically I'm trying to update the TextBlock on the main page using MVVM when the content the frame updates the the property. Please find the code attached below:[URL]..How do i get the button inside the frame to change the variable and update the TextBlock on the parent control?
If you were to upload a project to any site but are concerned about the large file size, what are the only files you need to zip up for your project to work for either VB 2008 or VB 2010? So far I know you don't need the exe's, the pdbs, and xml files.
1)This is my code.. (below)what i am trying to do here is to insert username and confirmed password into a sql table called login via a pre created form.I have 1 textbox, 2 Maskedtextboxes and a button.
what i would like is if the passwords do not match in both maskedtextboxes for the system to throw out a message saying passwords do not match please try again..which then clears previous content and requires the user to enter details again. once details are correct and system commits the new user details to the table and throws up a confirmation message.
I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim myFtpWebRequest As FtpWebRequest Dim myFtpWebResponse As FtpWebResponse
i would like to create a fixed size frame for user photos uploaded. I've tought: i, can create a fixed sized image (200 width x 600 height for example), with my personal frame (top, left, bottom, right element graphics) , and in the center a transparency.
Ok, but i don't know how to merge the photo into the frame and save the new photo format.
I'm using the code below to send large strings (500kB) to a server. I'd like to show the upload speed and in order to do that, I need to calculate the amount uploaded every second.
In a Timer that fires every second I get the BytesUploaded, divide it by 1024 in order to get KiloBytes (kB/s) and show it to the user. Then I set BytesUploaded to 0 and one second later do the same process.
The uploading is done asynchronously and the size of the data is added to BytesUploaded at once. This means that BytesUploaded is not being updated in a constant flow and has a totally different value almost every second.
