VS 2010 Error : Execute Is A Type In Ffmpeg Not An Expression
Oct 10, 2009
I am making a GUI for ffmpeg. And i want a own namespace for it. So you can ex. write in Form1.vb:
ffmpeg.Execute("The command to execute")
or
ffmpeg.SetType.CBR
But i can't get it to work.This is what i have:
Imports System.IO
Namespace ffmpeg
Public Class Execute
[code]....
In the execute option, it gives me an error of Execute is a type in ffmpeg, not an expression.In the SetType thing, the two subs doesn't even come up when i call it.
I am working on an application in Visual Basic Express using an Access 2000 database.I am trying to get athe following SQL query to work but get an error in Access.
The query is:
SELECT [ID], [Title], [Author], [Series], [YearPublished], [ISBN], [CoverPrice], [Style], [Condition], [Signed], [Comments], Count([Title]) AS CountOfBooks, Sum([CoverPrice]) AS TotalCoverPrice FROM tblBooks WHERE ID=[@ID];
The error is:"You have tried to execute a query that does not include the spec ified expression 'ID' as a part of the aggragate function."
The query works fine without the 'Count' and 'CoverPrice' count and sum to the query.
basically i have 16 checkboxes that indicate the status of digital inputs, either checked or unchecked, but rather than adress each and every one of them with a pile of repetative code, i set up a for-next loop and tried to change the status of the checkboxes with - is for index = 0 to 15, if blah=true then checkbox(index) = checked else checkbox(index) = uncheckedBut i get error- checkbox is a type and cannot be used as an expression.
i already converting to integer, but why still got the error when create new record?Data type mismatch in criteria expression.
red section error
table (da) field itemcode(integer),description(text),Quantity(integer) my Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I have looked at this for hours and can't seem to figure out what is causing the datatype mismatch. I am trying to insert from asp.net to a access database
insert statement:(ignore the poor practice with the concat parameters)
Dim BSSQL As String = "insert into bodyshop (startdate, enddate, frontbump, rearbump, touchup, other, vehicleid)" & _ "values('" & StartDateBodyShopTXT.Text & "','" & FinishDateBodyShopTXT.Text & "','" &
[code]....
here is a snapshot of the table:the format of the yes/no fields is "true/false"
I have written an application for my family business. It works fine when I try it on my computer, which I've used to write the app. But it gets the "Data type mismatch in criteria expression" error when I try to save data on the computer where the app is installed and will be used on.I don't get it. Is it because of the operating system?
Dim edit1 As OleDbCommand = New OleDbCommand("select * from [exporter] where exp_id='" & t1.Text & "'", con1)
now:-
t1 is a textbox
and in my table exp_id is "Number" now when i run this i get an error at the time executing reader (Data type mismatch in criteria expression.) but when i change exp_id properties to "Text" it run's properly
So that error doesn't really make since. I mean I know what the error means but my query looks good and is what I expected.Is there any way to see the final outcome from SQLInsert. Parameters.AddWithValue..Before it gets to "SQLInsert.ExecuteNonQuery()" ??
I've got the following code to search for data from my database, but when I run the code its giving me a 'Data type mismatch in criteria expression.' but I cant for the life of me work out why
To fill my table I use: OleDbDataAdapter1.Fill(TAS_DataDataSet)
Then use the following to try and search for data by the employee ID;
Private Sub comboEmployee_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles comboEmployee.SelectedIndexChanged Dim EmployeeID, SQLString As String
(Not really sure if I phrased the question correctly...) I want to create a lambda expression that would take an Object, attempt to convert it to a passed-in Type, and print to the console whether it was successful or not. At a glance, the lambda expression may seem a pretty silly way to accomplish this task, but I'd really like to know what I'm doing wrong, so I can better grow my skill set.
VS gives me a designer error about the second "T" in the expression below, telling me it isn't defined) This is where I left off:
I've just finished installing VS2010 on my computer. I have a project I built in 2003 that I'm trying to open in 2010. It went through the conversion process and generated this error: System.SystemException - The type library importer encountered an error during type verification. Try importing without class members. : System.MissingMethodException - Method not found: 'Void
I work with C# 99% of the time. However, I'm having to update some legacy VB.Net code and encountering an issue with VB.Net code syntax. The error that I get is "ByRef" is underlined and "Expected Expression" tag shows up when you hover over "ByRef". The "FooDetail.Load" function is written in C# and expects a List object passed as reference. Don't have any trouble using the same function in other C# classes. Can someone indicate what is wrong with below VB.Net code.
Dim FooDetail As New clsFooDetail() FooDetail.FooID = FooID Dim lstFooDetail As New List(Of clsFooDetail) FooDetail.Load(ConnectionString, "Stored Procedure", ByRef lstFooDetail as System.Collection.List(Of(clsFooDetail))
I have an error ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. and I've been trying to solve this but unfortunately I couldn't get the hack of this error. I'm a newbie in dotNet.
Public Sub LogInContinue(ByVal senter As Object, ByVal e As EventArgs) Dim LibDS As DataSet = New DataSet Dim LibDA As OdbcDataAdapter = New OdbcDataAdapter("SELECT * FROM tblUserAccount WHERE Uname='" & txtUserName.Text & "'", LibConn)
I want to pass an optional parameter to a function of type System.Drawing.Color. The problem I am having is that when I declare the function it says "Constant expression is required" but I have tried variations of the following, including integers, full qualified indentifiers, even old vbWhite constants to no avail.
I dont get this. I use code from one project that works and paste into anther and now its full of errors.
I have no clue how to solve this (See attached image).All of the errors have to do with Excel and Outlook applications.The info for "Imports" section is the same as my other project and all the "Dims" are the same as well. (These are two separate projects).Basically, I copied a form from one app and made a stand alone app for that form.
I'm trying to create a dynamic html page from vb.net. Here is my code. I get the error "'DataTable' is a type and cannot be used as an expression" ' Create a new XML document.
Dim xmlDoc As XmlDocument = New XmlDocument ' Create the html tag. Dim xmlRoot As XmlElement = xmlDoc.CreateElement("html") xmlDoc.AppendChild(xmlRoot)
I'm using FFMPEG for the first time. The upload works. The *.avi file is uploaded to the virtual path just fine. When it runs through and attempts the conversion to an FLV file, it doesn't error out - but it doesn't convert the file either. The ffmpeg.exe and pthreadGC2.dllare in the same folder ({virtual_path}uploadvideo). I do see a cmd window flash when the process starts but can make out anything displayed.
Here's my code: File Upload Protected Sub Submit1_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit1.ServerClick If Not File1.PostedFile Is Nothing And File1.PostedFile.ContentLength > 0 Then Dim GetFileName As String = File1.PostedFile.FileName Dim fn As String = System.IO.Path.GetFileName(File1.PostedFile.FileName) [Code] .....
Its been a while since I posted here as i've moved away from VB for the last few months. Anyway, seen as the support is so good here, i'm having with ripping MP3 files out of a MP4 video using ffmpeg.
Here's my code so far, but for some reason it doesn't want to work for me
Imports System.IO Public Class Form1 Dim process As New Process
how to convert videos files using vb.net and ffmpeg. But as far as i know we cannot use multiple threads to run same exe file to convert files. Do you know how i can convert multiple videos using one external exe file (ffmpeg)?
I have not tried because my computer time was over. So iam just asking a general doubt whether if we attach it to one process then wouldn't the process get locked? Then can we multi-thread this application or not ?
